What is a Martech Marketing Agency?

A martech marketing agency is a B2B marketing firm that markets to marketing-technology vendors, whose buyers (CMOs, VP Marketing, RevOps, and marketing-ops leaders) are themselves marketers and judge every tactic critically. The best ones tie HubSpot, Marketo, and Salesforce fluency and martech stack integration to pipeline and closed-won revenue.

Because the buyer critiques generic tactics at the first touch, fit is decided by platform certifications, named martech-vendor clients, and how attribution maps MQL to SQL to pipeline to closed-won MRR, not by channel breadth alone. Which agency fits depends on your ARR stage, your CRM of record, and whether you need demand gen, RevOps, brand, or all three.

The 13 Best Martech Marketing Agencies Compared

How We Chose These Martech Marketing Agencies?

Named clients, certifications, and pricing came from each agency’s own site and verified Clutch or FeaturedCustomers profiles, cross-checked against G2 and buyer threads in r/marketing and r/SaaS. Metadata.io was excluded as a software product with an optional managed layer, not a martech marketing agency .

For martech, two factors dominated: partner-tier certifications (HubSpot Elite, Marketo, Salesforce, Act-On) and whether named clients are actual martech vendors. Several agencies carry zero Clutch reviews, so FeaturedCustomers and on-site case studies did the verification. Full process: our research methodology .

Detailed Comparison of the Best Martech Marketing Agencies

1. Directive Consulting

Best for: $5M+ ARR martech vendors that want pipeline tied to closed-won ARR

Directive Consulting runs Customer Generation, a methodology that rejects MQL and traffic as primary KPIs in favor of pipeline contribution and closed-won ARR. They’ve worked with Cisco, ZoomInfo, Seismic, Sumo Logic, Snowflake, and Adobe.

Vendor Snapshot

The Edge: Directive treats demand gen as a revenue function, not a channel function.

The Customer Generation playbook starts from ICP, reverse-engineers paid and organic programs around that account list, and reports against pipeline rather than form fills. They claim $1B+ in client revenue generated for B2B brands.

• Google Premier Partner and LinkedIn Partner credentials
• Paid search, paid social, SEO, programmatic, and RevOps in-house
• Pipeline-first reporting is the default contract structure

On The Record

Love: Embedded operator feel A Director of Demand Generation called them “embedded in our organization” and credited their SaaS pipeline literacy on Clutch .

• Reviewers on Clutch repeatedly mention the team’s revenue language and weekly pipeline reviews.

Complain: Premium pricing floor Buyers under Series A flag that the ($8K+/mo) retainer model is overkill for ICP discovery work, per Clutch feedback.

• Pre-PMF teams report process overhead exceeds their early-stage needs.

Receipts: Directive has shipped programs for Cisco, ZoomInfo, Seismic, and Snowflake. Their public revenue claim is $1B+ generated for clients, with the full case-study library at directiveconsulting.com.

Investment Notes

Pricing isn’t published as of June 2026. Retainers run roughly $8,000 to $25,000+/mo based on scope, and engagement starts via the contact form on their site.

Where It Snags: No formal HubSpot or Marketo partner tier advertised. For martech vendors that need a platform-certified partner, Directive’s strength is methodology and channel mix, not stack implementation.

• Not built for ICP discovery or early demand-shaping work
• Pricing floor excludes most pre-Series A teams

Right Caller: $5M+ ARR martech vendor with an established sales motion and a board that asks about pipeline by source.

Wrong Caller: Pre-Series A founder still validating ICP or needing HubSpot implementation work.

Our Read: We rate Directive at the top of any martech shortlist when the buyer already has a repeatable sales motion and wants pipeline contribution made auditable.

2. PipeRocket Digital

Source: piperocket.digital · Screenshots captured May 2026

Best for: B2B SaaS and martech teams that want one pipeline number across every channel

We’re PipeRocket Digital , a B2B SaaS demand-gen pod (about 25 people) running SEO , PPC , GEO/AEO , and marketing ops for clients like LeadSquared , Storylane, GreytHR, Tredence, DevRev , and Spendflo. LeadSquared and Storylane are martech vendors themselves.

Vendor Snapshot

The Edge We Bring: Senior pod model, not a generalist account team.

Every account gets four practitioners (SEO, paid, content, ops) plus a strategy lead. We report MQL to SQL to pipeline to closed-won MRR weekly, not monthly. No ad-spend minimums, monthly rolling contracts.

• Google and LinkedIn certifications across the senior pod
• Pipeline attribution wired into HubSpot or Salesforce on day one
• AEO/GEO work for AI search surfaces shipped before most peers picked up the brief

On The Record

Love: Strategic at our scale A founder told Clutch , “They’re strategic thinkers and work according to the scale of our business.” Our Clutch profile sits at 4.7/5 across 18 reviews.

• Buyers cite the senior pod model over the junior-AM-plus-offshore structure most agencies run.

Complain: Not built for $100K+/mo paid We’re transparent about this: at high paid spend or with a brand and PR brief, you’ll want a larger shop.

• Timezone overlap with the US East coast caps to about four hours of live collaboration per day.

Receipts: Our work for LeadSquared (marketing automation), Storylane (interactive demos), and GreytHR (HR tech) is the closest peer comparison to a martech vendor in book. Pipeline reporting examples are in case studies on piperocket.digital.

Investment Notes

Pricing starts at $3,000/mo as of June 2026. We hold monthly rolling contracts and don’t enforce ad-spend minimums.

Where It Snags: We don’t run in-house PR or brand work, and at $100K+/mo paid spend we’d hand off to a larger media specialist. Timezone friction is real for clients that need same-day US-hours response on every channel.

• No in-house creative production studio
• Brand strategy and PR are out of scope

Right Caller: B2B SaaS or martech vendor between $1M and $20M ARR that wants integrated demand gen on one pipeline target.

Wrong Caller: Consumer marketing tool, or a team that wants channel-by-channel reporting without pipeline attribution.

Our Read: We built PipeRocket for the operator who’s tired of decoupled retainers and dashboard theater, and we think it shows in how clients describe our weekly reviews.

3. Walker Sands

Best for: Growth-stage and enterprise martech vendors that want brand, demand, and PR under one roof

Walker Sands is a Chicago B2B agency that brings brand, demand generation, PR, social, and data and analytics together for growth-stage and enterprise technology companies. Founded in 2001, it is one of the longest-running B2B tech marketing shops on this list, with additional offices in Seattle and Boston.

Vendor Snapshot

The Edge: PR and brand weight most demand-gen shops don’t carry.

Walker Sands runs brand, demand, PR, social, and data and analytics inside one engagement, which lets a martech vendor pair pipeline programs with earned media and analyst relations. The bench skews senior on B2B technology positioning.

• Brand, demand, PR, social, and analytics under one roof
• 20+ years focused on B2B technology
• Growth-stage through enterprise coverage

On The Record

Love: Trusted-advisor account management A Director of Marketing at Haley & Aldrich called the team “a trusted advisor for me” on Clutch .

• An investment-firm VP said they delivered “a slick and professional site that is easy to navigate and manage,” per Clutch .

Complain: Depth thin in niche verticals Clutch reviewers flag limited depth of expertise in some complex or niche industry sectors, plus occasional design-output gripes and minor post-launch QA bugs.

• Glassdoor reviewers (4.0/5 across 95 reviews) cite compensation below industry benchmarks, which can pressure staffing continuity.

Receipts: 4.8/5 across 9 verified Clutch reviews plus a FeaturedCustomers references profile at 4.7/5. Named work includes a 15% year-over-year revenue lift at Dotcom Distribution and media-relations results for eyeSight.

Investment Notes

Walker Sands doesn’t publish pricing as of August 2026; engagement starts via the contact form on their site.

Where It Snags: No published pricing and no dedicated martech vertical page. Martech credibility comes from B2B-tech adjacency rather than a named martech practice or martech-vendor case studies.

• No public rate card
• Broad B2B-tech focus rather than martech-specific specialization

Right Caller: Growth-stage or enterprise martech vendor that wants brand, demand, and PR from one agency.

Wrong Caller: Early-stage martech team on a boutique budget that needs a single pipeline number without a brand-and-PR program.

Our Read: We think Walker Sands earns the shortlist when a martech vendor needs PR and brand weight alongside demand gen, which most performance shops on this list can’t offer in-house.

Checking references? Read our Walker Sands reviews breakdown of their Clutch, G2, and Glassdoor scores.

4. Studio Sunup

Best for: Martech vendors that need senior-led brand strategy, identity, and creative

Studio Sunup (Sunup) is a Chicago tech branding studio that turns complex technical products into market-facing brands through strategy, identity, and creative, led by senior talent. Its scope is brand and creative rather than full-funnel demand generation, so it sits narrower than most entries here.

Vendor Snapshot

The Edge: Senior-only brand and identity work for technical products.

Studio Sunup keeps strategy, identity, and creative under senior practitioners, which fits martech vendors that need positioning and visual identity for a complex product before or alongside a separate demand partner.

• Strategy, identity, and creative under senior talent
• Built for complex, technical positioning
• Brand and identity as the starting point

On The Record

Love: Strong signal on a small sample Studio Sunup holds a 5.0/5 Clutch rating across 3 reviews as of August 2026, a clean score on a thin base.

• Reviewers value the senior-led brand work, though the 3-review sample is directional rather than statistical.

Complain: Sample size and narrow scope Only 3 Clutch reviews means the signal isn’t deep, and the studio doesn’t run paid, SEO, or pipeline execution.

• No demand-gen, attribution, or martech platform integration in scope.

Receipts: 5.0/5 across 3 Clutch reviews is the verifiable evidence. Client roster and pricing are not publicly disclosed as of August 2026.

Investment Notes

Pricing is not publicly disclosed as of August 2026; engagement starts via the studio’s contact form.

Where It Snags: No demand generation, no paid or SEO execution, and no martech platform certifications. This is a brand and creative engagement only.

• Not a pipeline or attribution partner
• Client list not public

Right Caller: Martech vendor that needs a senior-led brand and identity overhaul before or alongside a separate demand partner.

Wrong Caller: Team looking for pipeline, paid, SEO, or martech stack integration in the same engagement.

Our Read: We include Studio Sunup because it surfaces in AI answers for martech branding, and we’re honest that it’s a brand-and-creative studio, so pair it with a demand partner for pipeline work.

5. G&CO

Best for: Enterprise martech and tech brands that want customer-experience, commerce, and transformation work

G&CO is a New York agency that positions as “The Customer Experience Partner,” blending strategy, digital transformation, AI and data, and commerce for enterprise brands. Named work includes Lululemon and Hims. Its center of gravity is CX and commerce rather than martech demand generation.

Vendor Snapshot

The Edge: Enterprise CX and commerce transformation.

G&CO pairs strategy with AI and data and commerce build-out for enterprise brands, which suits a martech vendor that needs customer-experience or commerce work rather than channel demand gen.

• Strategy, AI and data, and commerce in one practice
• Enterprise-scale engagements
• Named consumer and enterprise brands in book

On The Record

Love: Enterprise brand credibility G&CO’s public work with Lululemon and Hims signals enterprise-scale delivery on customer-experience and commerce programs.

• Positioning centers on measurable customer-experience outcomes.

Complain: No verified rating and off-center for martech There’s no verified Clutch or FeaturedCustomers profile to triangulate, and the practice skews CX and commerce rather than martech demand gen.

• A same-name “gco-design-studio” Clutch profile is a different Polish design studio; don’t conflate the two.

Receipts: Public client work (Lululemon, Hims) is the available evidence. No verified review-platform rating exists as of August 2026.

Investment Notes

Pricing is not publicly disclosed as of August 2026; engagement starts via a contact form.

Where It Snags: No verified review-platform rating and no dedicated martech practice. For a martech vendor, the fit is customer experience and commerce, not pipeline demand gen.

• Rating unverifiable due to a namesake collision
• Not a demand-gen or paid-media partner

Right Caller: Enterprise martech or tech brand that needs customer-experience, commerce, or transformation work.

Wrong Caller: Martech vendor that wants pipeline, paid media, or martech stack integration as the core deliverable.

Our Read: We include G&CO because it appears in AI answers for the category, and we’re upfront that its strength is enterprise CX and commerce, with no independent rating we could verify.

6. Refine Labs

Best for: $50M+ ARR martech vendors buying the demand-creation thesis

Refine Labs reframed B2B demand gen around dark-social and intent signals, building the “Brand, Demand, and Expand” framework. They’ve worked with Clari, Cognism, FirstUp, and EveryoneSocial.

Vendor Snapshot

The Edge: Methodology-led, not platform-led.

Refine Labs distinguishes demand capture (chasing in-market buyers) from demand creation (building preference before buyers enter active evaluation). Their book is heavy with martech and sales-tech vendors that fit that thesis.

• Paid social and podcast distribution sit at the core of execution
• Pipeline attribution model rejects MQL as the primary contract metric
• Public pricing on the site, rare among premium agencies

On The Record

Love: Pipeline lift over baseline FirstUp publicly reported a 46% increase in hand raisers and 59% growth in HIRO pipeline year over year, sourced via refinelabs.com .

• Buyer reviews on b2bsaasreviews.com flag the dark-social attribution work as the strongest differentiator.

Complain: Leadership transition Chris Walker exited as CEO in July 2025 (Megan Bowen now leads), and buyers on b2bsaasreviews.com ask whether the methodology survives founder departure.

• Pricing floor at $20K/mo excludes capture-focused teams.

Receipts: Public Firstup outcome (46%/59% lift) and the named martech-heavy client list (Clari, Cognism, FirstUp) are the strongest evidence base. Full pricing is published at refinelabs.com/pricing.

Investment Notes

Refine Labs publishes pricing as of June 2026, which is unusual. Engagement starts with a $35,000 one-time assessment.

Where It Snags: No SEO, no RevOps execution, no ABM ops. Service set is narrower than the integrated shops, and post-Walker leadership continuity is an open question for new buyers.

• Zero verified Clutch reviews (profile exists, 0 reviews)
• Pricing floor excludes anything below $50M ARR

Right Caller: $50M+ ARR martech or B2B SaaS company with $50K+/mo paid budget that wants demand creation, not lead capture.

Wrong Caller: Sub-Series B team that needs SEO, RevOps execution, or full-funnel ABM operations.

Our Read: We think Refine Labs is the cleanest expression of the demand-creation thesis, and the right fit when the buyer already believes the thesis before the first call.

7. SmartBug Media

Best for: Martech vendors built on HubSpot needing RevOps and lifecycle automation

SmartBug Media is the 2025 HubSpot North American Partner of the Year and a HubSpot Elite Solutions Partner. They’ve worked with Ashling Partners, TestMonitor, and Access.

Vendor Snapshot

The Edge: Deepest HubSpot bench in the listicle.

SmartBug’s HubSpot certifications go to the top tier, and their 2025 NA Partner of the Year status is the highest single accolade in this space. RevOps, lifecycle automation, inbound, content, SEO, and paid all sit under one roof.

• HubSpot Elite Solutions Partner (highest tier)
• Seven verticals served (SaaS is one of them)
• Web design, technical CMS, and lifecycle automation in-house

On The Record

Love: Indispensable extension of the team A senior director called them “an indispensable extension of our team” handling technical HubSpot work on Clutch .

• An industrial distributor on Clutch praised their ability to “adapt to our needs.”

Complain: Industry sprawl Healthcare, senior living, manufacturing, franchise, finance, and education all sit in the verticals list, which buyers on Clutch note can dilute pure-martech credibility.

• Not a fit if your CRM-of-record is Salesforce or anything outside HubSpot.

Receipts: 2025 HubSpot NA Partner of the Year is the headline. Case studies for Ashling Partners (intelligent automation) and TestMonitor (IT software) are on smartbugmedia.com.

Investment Notes

SmartBug bills at $150 to $199/hr as of June 2026, with no public minimum project size disclosed. CTAs route through “Let’s Talk” rather than a published rate card.

Where It Snags: HubSpot-first means HubSpot-only depth. If your martech product competes with HubSpot or sits primarily in the Salesforce stack, the platform skew works against you.

• No equivalent Marketo or Salesforce partner tier
• SaaS sits in a seven-vertical portfolio, not the flagship vertical

Right Caller: Martech vendor whose product complements or integrates with HubSpot, with an existing HubSpot CRM-of-record.

Wrong Caller: Salesforce-primary martech vendor or any team where HubSpot fluency isn’t a buying criterion.

Our Read: We think SmartBug is the obvious call for any martech vendor whose own product or buyer base lives inside HubSpot. (In January 2026, SmartBug rebranded its digital advertising division as Point Success Media; the core HubSpot RevOps practice is unchanged.)

Rating picture: our SmartBug Media reviews page collects their client and employer scores.

8. 42DM

Best for: Martech vendors that want the only agency with an explicit /martech/ vertical page

42DM runs an explicit /martech/ vertical practice covering MarTech and GenAI. They’ve worked with Payoneer, Roland Berger, Lumin, Reface.ai, and MentionMe.

Vendor Snapshot

The Edge: Only agency in this set with a dedicated /martech/ landing page .

42DM’s martech practice covers ABM , marketing analytics, attribution, automation, and AI-driven campaign execution. PPC is half of services delivered, which signals where the bench is deepest.

• HubSpot certified partner and Google Partner
• AI-driven execution baked into the campaign operating model
• Industries: IT (30%), financial services, business services, e-commerce

On The Record

Love: Structured client service A former CEO told Clutch , “Their well-structured approach to client service and delivery really made a difference.”

• A marketing manager on Clutch called their scalability and cost-efficiency “unmatched.”

Complain: Offshore signal in pricing $50 to $99/hr is meaningfully below US peers, which buyers on Clutch read as a global delivery model.

• Named client roster leans general B2B and e-commerce more than pure martech.

Receipts: The /martech/ vertical page lists Payoneer (fintech SaaS), Zeeto, and Lumin as the martech-adjacent case studies. 18 verified Clutch reviews, 4.8/5 aggregate.

Investment Notes

42DM bills $50 to $99/hr with a $1,000+ minimum project as of June 2026. Engagement is time-and-materials for pilots and retainer for ongoing work.

Where It Snags: The hourly rate and team distribution suggest offshore delivery, which can mismatch a US martech CMO’s expectation of stateside platform depth. PPC-heavy mix means less SEO and content bench than the integrated shops.

• Named clients (Payoneer, Reface.ai) are martech-adjacent, not pure martech
• No formal Marketo or Salesforce certification advertised

Right Caller: Martech vendor that wants paid-heavy demand gen with an agency that names martech as a practice area.

Wrong Caller: Buyer who needs US-stateside delivery or deep content and SEO benches.

Our Read: We rate 42DM as the cleanest “they actually claim martech” pick, with the caveat that the named-client roster runs lighter on pure martech than the positioning suggests. (CEO Kate Vasylenko presented at NY Tech Week 2026 in June on scaling B2B revenue with AI, reinforcing the agency’s push into AI-driven GTM.)

9. New Breed

Best for: Martech teams that need HubSpot and Salesforce alignment as the demand-gen foundation

New Breed is a three-time HubSpot North American Top Partner and a HubSpot Elite Solutions Partner positioned as a “revenue performance management firm.” Talmundo (employee onboarding SaaS) is named on the homepage.

Vendor Snapshot

The Edge: Strongest dual-platform fluency in the list.

New Breed is HubSpot Elite (top tier) and runs Salesforce integration work, which is the rarest combination in the martech-agency space. RevOps is the entry point; demand gen and content sit downstream.

• HubSpot Elite + 3x NA Top Partner
• Salesforce integration capability (no formal partner tier advertised)
• RevOps-first contract structure

On The Record

Love: RevOps before campaigns Buyer feedback on newbreedrevenue.com case studies (Talmundo) credits the RevOps-first sequencing for fixing attribution before adding spend.

• Reviewers value the dual HubSpot/Salesforce fluency they don’t find elsewhere.

Complain: Thin named-client roster Only Talmundo surfaces publicly on the homepage, and there are no Clutch reviews to triangulate, per Clutch .

• Slower time-to-pipeline than direct-response shops because RevOps work front-loads the engagement.

Receipts: HubSpot Elite + 3x NA Top Partner is the headline. Talmundo case study on newbreedrevenue.com shows the RevOps-first sequencing in practice.

Investment Notes

Pricing isn’t public as of June 2026; engagement is “Request a Quote” only. Industry expectation for HubSpot Elite shops with Salesforce integration is upper-quartile retainer.

Where It Snags: Zero verified Clutch reviews despite 20+ years operating, and only one named martech-adjacent client public-facing. Buyers should ask for direct references during evaluation.

• No public retainer floor
• Salesforce work is integration, not formal partner-tier

Right Caller: Martech vendor with fragmented HubSpot and Salesforce data that needs the operational layer fixed before adding spend.

Wrong Caller: Buyer that needs fast direct-response paid pipeline without RevOps foundation work.

Our Read: We think New Breed is the strongest platform-fluency pitch on the list, and the zero-Clutch-reviews gap is the only thing keeping it out of the top three.

10. Ironpaper

Source: ironpaper.com · Screenshots captured May 2026

Best for: B2B martech with existing inbound traffic that isn’t converting cleanly to pipeline

Ironpaper is a HubSpot Diamond Certified Agency Partner focused on lead quality improvement and funnel optimization. Named clients include Solartis, SiteX, Steelcase, Mobilewalla, and Sparks Group.

Vendor Snapshot

The Edge: Funnel-first diagnostic before adding acquisition spend.

Ironpaper’s model starts with diagnosing where qualified buyers drop out of the funnel, then builds content, nurture, and conversion programs to recapture pipeline before scaling top-of-funnel spend.

• HubSpot Diamond Partner (one tier below Elite)
• Dedicated “HubSpot for ABM” offering
• Web design, UX/UI, and dev capability in-house

On The Record

Love: Funnel diagnostic depth On-site testimonials on ironpaper.com cite the funnel diagnostic as the work that justified the retainer.

• Buyers value the focus on conversion before acquisition spend.

Complain: Industry mix isn’t martech Per Clutch , industry mix is Media (30%), Telecom (15%), Hospitality (15%), with martech not surfaced as a vertical.

• Zero Clutch reviews despite a 20+ year history.

Receipts: HubSpot Diamond certification and 20+ year operating history are the structural credibility. Case studies for Solartis, SiteX, and Steelcase are on ironpaper.com, but none are pure martech.

Investment Notes

Ironpaper bills $200 to $300/hr with a $25,000+ minimum project as of June 2026. No public retainer page.

Where It Snags: Zero verified Clutch reviews and an industry mix dominated by media, telecom, and hospitality. Martech credibility is structural (HubSpot Diamond) rather than client-evidenced.

• $25K+ project minimum is premium for diagnostic work
• No martech-named clients on public case studies

Right Caller: B2B martech vendor with $50K+/mo existing inbound traffic that isn’t converting at the rate the funnel suggests it should.

Wrong Caller: Pre-revenue martech vendor with no traffic to optimize, or a team needing demand creation from scratch.

Our Read: We think Ironpaper earns a place when the buyer can articulate a specific funnel break, and loses ground when they’re scanning for net-new pipeline.

Checking references? Read our Ironpaper reviews breakdown of their Clutch, G2, and Glassdoor scores.

11. Powered by Search

Source: poweredbysearch.com · Screenshots captured May 2026

Best for: Enterprise SaaS with long sales cycles, especially security-adjacent martech

Powered by Search runs B2B SaaS demand gen via their “SaaS Demand Gen Pyramid” framework. Named clients include Fortra, ThreatX, PointClickCare, iWave, TouchBistro, and Cyera, a cybersecurity-heavy roster.

Vendor Snapshot

The Edge: Buying-committee marketing for long sales cycles.

The SaaS Demand Gen Pyramid structures campaign investment around pipeline stage rather than channel budgets. Methodology fits enterprise martech buying with procurement, IT, and CMO involvement, even though the named-client roster leans security.

• HubSpot partner and Google Partner credentials
• Integrated paid + SEO + ABM under one team
• $100M+ in pipeline reported annually across clients

On The Record

Love: Strategic paid media transformation A client on poweredbysearch.com said the team “completely transformed our paid media strategy .”

• Buyer signal on FeaturedCustomers (4.8 score) reinforces the methodology.

Complain: Cybersecurity-heavy in book Named clients on poweredbysearch.com skew cybersecurity (Fortra, ThreatX, Cyera), so martech depth is by methodology, not client adjacency.

• Zero verified Clutch reviews, despite the strong on-site testimonial set.

Receipts: Fortra, ThreatX, PointClickCare, and Cyera are public clients. Pipeline figure ($100M+ annual across clients) is on the site, framed around the Pyramid methodology.

Investment Notes

Powered by Search bills $200 to $300/hr with a $5,000+ minimum project as of June 2026. No published retainer floor.

Where It Snags: Named-client roster is cybersecurity-heavy, so martech credibility comes from methodology rather than client list. Zero verified Clutch reviews despite a 16+ year history.

• Hourly rate is upper-quartile
• Martech is by methodology adjacency, not vertical specialization

Right Caller: Enterprise martech vendor with committee-driven buying, especially in security-adjacent categories.

Wrong Caller: PLG or self-serve martech product where the buying motion is individual and low-friction.

Our Read: We think Powered by Search earns the shortlist for enterprise martech buyers but should be honest with you: their best work is cybersecurity-shaped, not martech-shaped.

Also weighing Powered by Search? See our roundup of the best Powered by Search alternatives .

12. Kalungi

Source: kalungi.com · Screenshots captured May 2026

Best for: VC-backed Series A to C martech founders needing fractional CMO plus execution

Kalungi runs Growth-as-a-Service: fractional CMO leadership plus full GTM execution built on the T2D3 playbook. Named clients include CPGvision, BPLogix, BotDojo, HopSkip, Aware360, and SocialLadder.

Vendor Snapshot

The Edge: Senior leadership without the full-time hire.

A fractional CMO plus an execution team across SEO, paid, content, brand, RevOps, and web sits inside one engagement. The T2D3 playbook gives founders a structured growth model from $1M to $5M ARR .

• HubSpot partner credentials
• Fractional CMO is shared across accounts, not dedicated
• T2D3 playbook templates the engagement from intake

On The Record

Love: Strategic partner energy A client on FeaturedCustomers said the team “really felt like a partner and someone that cared about our business.”

• FeaturedCustomers carries 906 reference ratings triangulating the positioning work.

Complain: Fractional means shared The CMO model is shared across accounts (not dedicated), which buyers on FeaturedCustomers flag for fast-moving founders.

• Zero Clutch reviews, despite the strong FeaturedCustomers footprint.

Receipts: 906 reference ratings on FeaturedCustomers and a published client list (CPGvision, BPLogix, SocialLadder) cover the case. None of the named clients are pure martech.

Investment Notes

Kalungi bills $100 to $149/hr with a $25,000+ minimum project as of June 2026. Retainers cluster around $8,000 to $20,000/mo for full Growth-as-a-Service.

Where It Snags: Fractional means shared, so capacity caps at the enterprise tier. No Marketo or Salesforce partner-tier certification, and no pure-martech named clients on the public list.

• $25K+ project minimum
• Caps enterprise capacity at the fractional model

Right Caller: Series A to C martech founder ($1M to $5M ARR) post-PMF that needs senior leadership and execution under one engagement.

Wrong Caller: Martech company with an existing CMO, or any team that needs dedicated rather than shared senior leadership.

Our Read: We rate Kalungi as the cleanest fractional-CMO option for early-stage SaaS founders, and the right call only when the buyer accepts the shared-leadership trade-off (Antoine Vial named CEO in March 2026, with founder Stijn Hendrikse moving to Chairman).

If Kalungi isn’t quite the fit, check our Kalungi alternatives shortlist.

13. Cremarc

Best for: UK-based or UK-adjacent martech vendors that want Act-On and HubSpot fluency

Cremarc is the only agency in this set with a dedicated “Marketing technology” service page, explicitly positioning as a “B2B technology marketing agency.” Clients include SilverCloud (by Amwell), Plentific, Quantum, NAK, and Liquid Voice.

Vendor Snapshot

The Edge: The only Act-On partner in the listicle.

Cremarc holds HubSpot Solutions Partner, Act-On partner (unusual and meaningful for a martech-focused shop), and Google Partner credentials. Their “Marketing technology” service page is the most explicit positioning of any agency in this set.

• Dedicated “Marketing technology” service page
• Branding, content, automation, and attribution under one roof
• Act-On partnership is a martech-vendor signal in itself

On The Record

Love: Tech-native positioning On-site case studies on cremarc.com reinforce the B2B-tech-only framing buyers say they want.

• Reviewers cite the dedicated automation and attribution practice as the differentiator.

Complain: Thin third-party signal Zero Clutch reviews on Clutch , and named clients are broad B2B tech (industrial, recruitment, telecoms) rather than pure martech vendors.

• UK timezone (about 5 hours ahead of US East) creates async friction.

Receipts: Act-On partnership and the dedicated Marketing technology page are the structural credibility. SilverCloud (by Amwell, health tech) and Plentific (proptech) are the strongest case studies on cremarc.com.

Investment Notes

Cremarc bills $150 to $199/hr as of June 2026. No public retainer floor or minimum project size.

Where It Snags: Zero verified Clutch reviews, small team (21-30), and a named-client roster that’s broad B2B tech rather than concentrated in martech vendors. UK base adds timezone friction for US buyers.

• Team size caps enterprise scale
• No pure-martech named clients on case-study pages

Right Caller: UK-based or UK-adjacent martech vendor that wants explicit tech-marketing positioning and Act-On platform depth.

Wrong Caller: US enterprise martech buyer that needs same-timezone account management or a large delivery team.

Our Read: We think Cremarc earns the shortlist on positioning honesty, and the credibility gap is the named-client roster, not the methodology.

When to Hire a Martech Marketing Agency?

Hire a martech marketing agency when:

• You have product-market fit and a repeatable sales motion, and in-house bandwidth can’t scale pipeline
• Your team lacks deep HubSpot, Marketo, or Salesforce fluency to wire martech stack integration and attribution
• You can’t trace marketing spend to pipeline and closed-won revenue, and generic B2B tactics stall with your marketer-buyers

Not ready yet? A martech vendor without a clear value proposition, a defined ICP , or budget and patience for a genuine three-month test won’t get pipeline from an agency, only an expensive lesson. Sort positioning first if generic messaging is the real gap.

What to expect: Retainers run $3,000/mo at the boutique end to $31,000/mo for full-service demand gen, with most $1M-$20M ARR vendors in the $5,000-$15,000/mo band. Paid programs show pipeline contribution in 60-90 days; SEO, content, and demand creation compound over 3-12 months. The partners worth keeping report in SQLs, pipeline, and closed-won MRR, not impressions.

2. When should you hire a martech marketing agency?

Hire a martech marketing agency once you have product-market fit, a repeatable sales motion, and budget for a genuine three-month test. The trigger is when in-house bandwidth or HubSpot/Salesforce fluency can’t scale pipeline. Expect retainers of $3,000 to $31,000/mo and 60-180 days to real pipeline impact.

3. What’s the difference between a martech marketing agency and a B2B SaaS marketing agency?

A martech agency markets to marketers, the toughest audience because they critique every tactic. B2B SaaS agencies cover a wider buyer set.

4. How much should a martech vendor budget for a marketing agency in 2026?

Retainers range $3,000/mo (boutique) to $31,000/mo (full-service). Most martech vendors at $1M-$20M ARR sit in the $5,000-$15,000/mo band.

5. Which agencies have explicit martech vertical pages?

Only two: 42DM (/martech/) and Cremarc (Marketing technology service page). Most others serve martech as part of broader B2B SaaS work.

6. Should I prioritize HubSpot Elite status when shortlisting?

If HubSpot is your CRM or your product integrates with it, yes. SmartBug Media and New Breed are HubSpot Elite Partners here; Ironpaper is Diamond.

7. What’s the most common mistake martech vendors make hiring agencies?

Buying generic B2B demand gen without checking whether the agency has named martech-vendor clients. Methodology fit and platform fluency beat channel coverage.

Paid programs show pipeline contribution in 60-90 days. SEO and content take 3-6 months. Demand creation compounds over 6-12 months as authority accrues.
