Belkins Client Reviews
Clutch, G2, GoodFirms, and DesignRush all point to a strongly positive client picture built on outbound delivery against KPI targets, with a specific zero-leads complaint independently confirmed on G2 (verified September 2026).
Clutch: 4.9/5 (233 reviews)
Clutch’s profile spans reviews dated through at least early 2024, describing appointment-setting and outbound-sales engagements across IT services, medical technology, and adtech clients.
What clients praise:
- Deep outbound-sales and appointment-booking expertise, with one reviewer citing 23 booked appointments and a 100% KPI hit in the first month
- Responsive, collaborative process, repeated across multiple reviewers
- Proactive problem-scoping beyond the original brief
- Consistent deadline adherence and fast feedback turnaround
Where clients push back:
- A slower initial ramp-up, noted by one reviewer even while praising eventual lead quality
“They deeply understand outbound sales and are experts in generating leads and booking appointments.”
- Marketing Lead, IT Services Company, Clutch (Clutch )
G2: 4.7/5 (93 reviews)
G2’s star distribution is bimodal: 88 five-star reviews and 1 four-star against 4 one-star, with reviews running through July 2026. Reviewers cite specific pipeline figures alongside end-to-end outbound ownership.
What clients praise:
- End-to-end outbound ownership, from ICP definition and messaging through testing, booking, and reporting
- Measurable pipeline outcomes, including 78 meetings booked at a 45% open rate and 12% reply rate resulting in 6 closed deals, and a separate 57 qualified appointments booked
- Professionalism and responsiveness, repeated near-verbatim across several 2025 reviews
- Transparent reporting cadence on open rates, replies, and booked meetings
Where clients push back:
- A zero-leads complaint pattern confirmed by two separate reviewers, one reporting zero leads over a 2-month engagement with over two weeks to execute campaign tweaks, another reporting messaging errors and zero leads after four months
- Cost flagged as steep by at least one otherwise-positive reviewer
- Onboarding time flagged as longer than expected by one reviewer
“They are supposed to help with pipeline generation, they have had 0 leads / appointments in 2 months, we will be breaking the contract and dropping them, follow up seems to be slow and non-existent. They take over 2 weeks to make any tweaks or execute on a new campaign.”
- Verified User, Information Technology and Services, Mid-Market, 7/23/2026 (G2 )
GoodFirms: 5.0/5 (22 reviews)
GoodFirms shows a perfect score across sub-scores for quality, communication, and schedule, but with no negative reviews visible in the sample, this is a low-volume, skewed-positive profile rather than a fully representative one.
What clients praise:
- Lead-quality and conversion-rate improvement, including one reviewer citing a tripled ROI over six months
- Effective lead research and qualification feeding an improved sales pipeline
- Multi-channel execution across lead gen, appointment setting, email outreach, and LinkedIn
“Our engagement with Belkins over the last six months has been nothing short of transformative… Our lead quality improved dramatically, resulting in a higher conversion rate and a tripling of our ROI.”
- Serhii Ivanov, Owner, Komanda (GoodFirms )
DesignRush: 4.9/5 (16 reviews)
DesignRush’s own client-submitted score is 4.9/5 across 16 reviews. The same profile also displays a separate “Google Rating: 4.5/5 (16 reviews)” line, which is a syndicated mirror of Google Maps read through DesignRush, not an independent Google Reviews source, so it is not reported here as its own row.
What clients praise:
- Fast initial deal closure and strong reported ROI, with one reviewer citing roughly $10 returned per $1 invested
- Responsive communication and data-driven project management
Where clients push back:
- One reviewer described an unusually negative experience and cautioned mid-market and larger companies specifically, though no further checkable detail was visible on the page
“Belkins exceeded expectations by securing contracts right off the bat. Their ability to deliver quick results was impressive.”
- Patrick Benasillo, CCO/Co-Founder, Visual Graphic Systems (DesignRush )
Trustpilot: 4.4/5 (14 reviews)
Trustpilot’s 14 reviews are a non-statistical sample. Reviews describe demand-generation and outreach engagements running alongside in-house marketing teams.
What clients praise:
- Multi-campaign outreach management aligned with in-house marketing, described as communicative and easy to work with
Where clients push back:
- Lead quality paired with a claim of high-pressure sales tactics during the buying process
“The pressure to join was intense. I have yet to see one lead that has been any good.”
- Joyce Ventre, Trustpilot (Trustpilot )
UpCity and Comparably remain unresolved rather than absent: UpCity’s domain would not load on repeated attempts, and its status as a discontinued public-profile platform is plausible but unconfirmed. FeaturedCustomers publishes 17 case-study references on its own page and separately states a platform-wide pool of 1,267 reference ratings at 4.8/5; those are two different samples, so no single FeaturedCustomers rating is reported here.
Clients across four platforms converge on the same strength: Clutch, G2, GoodFirms, and DesignRush all independently surface responsiveness and delivery of qualified appointments against KPI targets, each with specific numbers cited by reviewers.
G2 independently confirms a zero-leads complaint pattern that Clutch’s higher volume only hints at: two separate G2 reviewers, on 2-month and 4-month engagements, report zero leads or appointments, one adding slow campaign-adjustment turnaround. That is a specific, checkable tension sitting against a 4.9 Clutch score across 233 reviews.
Onboarding pace and cost surface as secondary friction on two platforms: both Clutch and G2 reviewers independently flagged a longer-than-expected ramp-up, and one G2 reviewer flagged cost as steep even while remaining otherwise satisfied.
Belkins Employer Reviews
Glassdoor is the only directly-read employer platform, showing a 4.2/5 across 41 reviews with 71% recommending the company and 84% approving of CEO Vlad Podolyako (verified September 2026).
Glassdoor: 4.2/5 (41 reviews)
Glassdoor’s profile is identity-confirmed to belkins.io via its structured data, and reviews run through late August 2026.
What employees praise:
- Flexibility and schedule autonomy, cited across multiple reviews including one from a 4-year employee
- Variety of industries and projects keeping the work engaging
- Strong team camaraderie among peers
Where employees push back:
- A fast-changing environment, with one 4-year employee describing constant adaptation to new directions, processes, and tech stacks as a genuine adjustment cost
“I’ve been working with Belkins for 4 years now, and one of the things I appreciate most is the flexibility… The day-off policy is another huge plus.”
- Senior Content Strategist, current employee, more than 3 years (Glassdoor )
Indeed, AmbitionBox, and Comparably: Indeed carries a live profile with zero reviews, AmbitionBox has no listing for this US/Ukraine-headquartered agency, and Comparably returned a hard access denial on three separate attempts, so its status could not be verified.
Clients and employees describe process from opposite directions: clients on G2 and Clutch praise structured, well-documented delivery, while Glassdoor’s most common internal theme is a fast-changing environment employees must keep adapting to. These are separately sourced observations from two different audiences, not cause and effect.
High approval numbers sit alongside that adaptation complaint: 84% approve of the CEO and 71% would recommend the company, figures that stand even as the fast-changing-environment theme recurs from a long-tenured reviewer.
Looking for a Belkins Alternative?
Belkins’ G2 reviews surface a specific tension: strong appointment-booking delivery for most clients against a confirmed zero-leads pattern on 2-4 month engagements for a minority.
