Seamless.AI vs ZoomInfo

The short answer

Seamless.AI and ZoomInfo both sell B2B contact data, but they solve different problems at different price points. Seamless.AI is a real-time, credit-based contact finder (Chrome extension plus web app) built for a rep to look up one person’s email or phone number on the spot, priced accessibly enough for individual reps and small teams. ZoomInfo is a full go-to-market intelligence platform (SalesOS, MarketingOS, OperationsOS) combining a much larger database with intent data, org charts, and workflow tooling, sold through a sales-led annual contract aimed at mid-market and enterprise revenue teams.

Choose Seamless.AI Fast, affordable single-contact lookups for individual reps

If you want a self-serve tool for finding one person’s direct contact info right now, work solo or on a small team, and want the lowest entry price (reported street pricing around $79 to $150 per user per month on paid tiers), Seamless.AI is the more accessible pick. Its free plan includes 50 lifetime credits.

Choose ZoomInfo Full GTM data platform with intent data and org charts

If you need intent data, detailed org charts, and a multi-product suite that spans sales, marketing, and operations, and you have budget for a sales-led annual contract (realistic mid-market spend commonly runs $25,000 to $50,000 a year), ZoomInfo is the stronger fit for a full revenue team.

Vendor profile

Seamless.AI

Real-time contact finder · Chrome extension + web app · credit-based pricing

Seamless.AI is a real-time, credit-based contact-finding tool built around a Chrome extension and web app that lets a rep search for a specific person’s email or phone number and get a result immediately, rather than working from bulk exports. Founded in 2015 by Brandon Bornancin and headquartered in Columbus, Ohio, the company markets itself heavily on scale claims (1M+ sales leaders, 2B+ leads researched) that are self-reported and not independently verified. It has no intent-data product and limited org-chart depth, and its public case studies are individual-reviewer testimonials rather than named enterprise logos. Paid tiers are quote-based, and reviewers repeatedly flag billing and cancellation friction on the annual, pay-upfront plans.

ZoomInfo

Enterprise GTM data platform · web app · sales-led annual contract

ZoomInfo is a full go-to-market intelligence platform spanning SalesOS, MarketingOS, and OperationsOS, built around a large B2B database, intent data (branded “Scoops”), detailed org charts, and Data-as-a-Service delivery including Snowflake-native feeds. Originally founded in 2007 as DiscoverOrg by Henry Schuck, the company acquired Zoom Information Inc. in 2019 and took the ZoomInfo name; it is headquartered in Vancouver, Washington and employs roughly 4,100+ people per LinkedIn. It claims 30,000+ customers company-wide and publishes named case studies with recognizable brands (Snowflake, monday.com, Seismic, OUTFRONT Media). The tradeoff is price and commitment: pricing is sales-led and quote-only, and realistic mid-market spend is commonly cited at $25,000 to $50,000 a year on an annual contract.

Capability comparison

Both tools help a sales team find and reach B2B contacts, but the depth and delivery model differ sharply. Seamless.AI is built for fast, single-contact, real-time lookups; ZoomInfo is built as a broader data and intent platform that most teams layer other tools on top of.

Service Seamless.AI ZoomInfo
Core product Real-time contact/email/phone finder + Chrome extension Full GTM platform: SalesOS, MarketingOS, OperationsOS
Data delivery model Credit-based, real-time “search now” lookups Bulk credits + platform search + Data-as-a-Service / Data Cubes
Intent data ✕ Not a core capability ✓ Core differentiator (Scoops, buyer intent signals)
Org charts / account mapping Partial (limited) ✓ Detailed org charts, account intelligence
Chrome extension ✓ Central to the product ✓ Companion to the full platform
API / bulk enrichment Partial (basic) ✓ Enterprise-grade APIs, Data Cubes, Snowflake native
Free tier ✓ (50 lifetime credits) ✕
Named enterprise case studies ✕ Individual-reviewer testimonials only ✓ Snowflake, monday.com, Seismic, OUTFRONT Media
Best-fit buyer Individual reps, SMBs, self-serve teams Mid-market to enterprise GTM/RevOps teams

Strengths & tradeoffs

Both tools do the core job (surface a contact’s details), and each side wins rows the other does not. The honest differences are scope, data depth, and price.

Axis Seamless.AI ZoomInfo
Core model Real-time, credit-based contact finder Full GTM data platform (Sales/Marketing/Operations OS)
Pricing floor Reported ~$79 to $150/user/mo, quote-based Reported ~$14,995+/yr entry, sales-led quote
Intent data None; not a core capability Core differentiator (Scoops, buyer intent signals)
Org charts / account mapping Limited Detailed, with account intelligence
Customer proof Individual-reviewer testimonials only, no named enterprise logos found Named case studies: Snowflake, monday.com, Seismic, OUTFRONT Media
Integrations Broader but shallower list, largely Zapier-dependent for the long tail Fewer but deeper native integrations, with signal-triggered automation (Salesloft Rhythm)
Contract terms Annual, paid upfront; recurring reviewer complaints about cancellation friction Annual only, auto-renewal; high price floor cited as a recurring complaint
Capterra satisfaction 4.5/5 (570 verified reviews) 4.1/5 (321 verified reviews)
Recurring accuracy complaints Outdated emails/phone numbers, especially outside North America Some reviewers report intent data as inconsistently accurate

Ratings & track record

Metric Seamless.AI ZoomInfo
G2 rating 4.4/5 (~5,000 to 5,300 reviews, verify live) 4.5/5 (~9,000 to 12,800+ reviews, range varies by page, verify live)
Capterra rating 4.5/5 (570 reviews) 4.1/5 (321 reviews)
Category Real-time contact finder Enterprise GTM data platform
Notable signal Higher Capterra satisfaction, lower price floor Larger review base; claims #1 in 142 G2 category reports (self-reported, unverified)

On the one review platform both vendors’ figures were directly confirmed live (Capterra), Seamless.AI scores higher: 4.5/5 across 570 reviews versus ZoomInfo’s 4.1/5 across 321 reviews. G2 is messier for both: G2 blocks automated fetch for each product page, so the numbers above are search-indexed snapshots, not confirmed live pulls, and should be re-checked before publishing anywhere that treats them as current. ZoomInfo’s claim of ranking #1 in 142 G2 Spring 2026 category reports comes from its own investor-relations press release, which could not be independently confirmed (the release and its BusinessWire mirror both failed to load during research); treat that specific claim as self-reported until verified. Review volume aside, the two platforms serve different buyers, so a rating gap is not the same as one tool being objectively better for every use case.

Both vendors’ data is sourced from publicly available information and third-party pricing/review aggregators as of July 2026. Several figures, including live G2 ratings, exact review counts, and both vendors’ paid-tier pricing, could not be fully confirmed via automated fetch; verify directly with each vendor before buying. This comparison is independent; we take no affiliate or referral fees from either vendor.

Frequently asked questions

What is the difference between Seamless.AI and ZoomInfo?
Seamless.AI is a real-time, credit-based contact finder built around a Chrome extension and web app, aimed at individual reps and small teams who need to find one person’s email or phone number quickly. ZoomInfo is a much larger go-to-market data platform combining a bigger database, intent data, org charts, and multi-product tooling (SalesOS, MarketingOS, OperationsOS) sold via a negotiated annual contract to mid-market and enterprise revenue teams. Seamless.AI is a lightweight prospecting tool; ZoomInfo is a full GTM data platform, at materially higher cost.
Is Seamless.AI cheaper than ZoomInfo?
Yes, by a wide margin, based on third-party pricing estimates (neither vendor publishes official paid-tier prices). Seamless.AI’s paid tiers are reported at roughly $79 to $150 per user per month, with a 5-seat team commonly landing at $4,740 to $9,000 a year. ZoomInfo has no public price list; reported entry tiers start around $14,995 a year, and realistic mid-market spend commonly runs $25,000 to $50,000 a year once seats and add-ons are included.
Does Seamless.AI include intent data?
No. Seamless.AI is built around real-time contact lookups, not intent data or org-chart depth, and the dossier found no standalone intent-data product on its site. Teams that need account-level buying signals will need to look elsewhere, including ZoomInfo, which publishes intent data (Scoops) as a core differentiator.
Which has better reviews, Seamless.AI or ZoomInfo?
It depends on the platform. On Capterra, Seamless.AI scores higher (4.5/5 across 570 verified reviews) than ZoomInfo Sales (4.1/5 across 321 verified reviews), confirmed directly from each vendor’s live Capterra page. On G2, both tools report ratings in the 4.4 to 4.5 range, but exact review counts vary by which G2 product page is cited (G2 blocks automated fetch for both, so treat any specific figure as needing a live check). ZoomInfo has a far larger overall review volume and market footprint.
Is Seamless.AI better than ZoomInfo?
Neither is better in the abstract; they serve different buyers. Seamless.AI is the better fit for a solo rep or small team that wants a fast, affordable, self-serve way to find a specific contact’s details. ZoomInfo is the better fit for a mid-market or enterprise revenue team that needs intent data, org charts, and a broader GTM data platform, and has budget for an annual sales-led contract. Reviewers on both sides also flag real weaknesses: Seamless.AI on data accuracy outside North America and cancellation friction, ZoomInfo on price floor and, per some reviewers, intent-data reliability.
When should a team choose ZoomInfo over Seamless.AI?
Choose ZoomInfo when the buying decision depends on more than a single contact record, for example when a team needs company-level intent signals, detailed org charts for account mapping, bulk enrichment via API or Data Cubes, or a platform that spans sales, marketing, and operations. ZoomInfo also publishes named enterprise case studies (Snowflake, monday.com, Seismic) that Seamless.AI does not have an equivalent for. The cost is a materially higher, sales-led annual contract with no public pricing.
