ZoomInfo is a B2B go-to-market intelligence platform founded in 2007 as DiscoverOrg and listed on Nasdaq as GTM. It sells company and contact data, buying signals and conversation intelligence with no published list price for core packages, and exposes the same data to AI agents through GTM.AI, an API, CLI and MCP server with a free starter allowance.
About ZoomInfo
ZoomInfo is a go-to-market data and intelligence platform from ZoomInfo Technologies Inc., which began as DiscoverOrg in 2007. The company's about page says Henry Schuck and a co-founder started it with $25,000 on their credit cards while he was in law school. DiscoverOrg bought ZoomInfo in 2019 and took its name, the company went public in 2020, and its Nasdaq ticker moved from ZI to GTM in 2025. Schuck is still CEO and the headquarters are in Vancouver, Washington. The vendor says its database covers more than 500 million contacts and 100 million companies and that 1,921 customers spend $100,000 or more a year in fiscal 2025. Those are the vendor's own figures.
Packaging splits into surfaces that price very differently. The classic web app is sold as Professional, Copilot Advanced and Copilot Enterprise for sales, Marketing Demand, ABM Lite and ABM Enterprise for marketing, plus Talent and Operations products, none with a published price. GTM Workspace is an AI workspace on top of the data, GTM Studio builds enrichment and workflows that fire on buying signals, and GTM.AI exposes the same data to agents through an API, a command line tool and an MCP server with a free starter allowance. Its Web Research agent puts it under the web browsing filter, and the free starter credits put it under the free tier filter. Chorus, its conversation intelligence product, analyses sales conversations.
The newest layer is aimed at AI assistants. GTM.AI lists clients such as Claude Code, Codex (OpenAI's tool, see OpenAI) and Perplexity, and the Claude Code install is one plugin command for the tool from Anthropic. Search and lookup calls cost nothing; credits are spent only when a call enriches a record or runs a research agent, and the two pools are separate. The vendor's own GTM Bench v1 reports about 460K work tokens against 11.1M for Claude alone with web search across 10 research tasks run on Claude Opus 4.8. Read that as a vendor test, not an independent one.
Apollo undercuts ZoomInfo on entry cost with a free plan, and Clay assembles data from many providers inside a workflow table. ZoomInfo's own comparison names Apollo, Lusha, Cognism and Clay. For call analysis, Gong competes with Chorus. The data usually feeds a sequencer such as Reply.io and a CRM such as HubSpot, and the vendor lists a native n8n integration. For the wider field of sales-data products, a guide to the best AI SDR products compares them, and the AI SDRs directory lists more.
ZoomInfo is registered as a data broker under Texas law and runs a self-service privacy center where people can act on their data rights. The vendor names B2B companies with 100 or more employees as its audience, across sales, account management, marketing and RevOps. On compliance, the vendor reports a completed SOC 2 audit and several ISO certifications, so it appears under the SOC 2 filter, the ISO 27001 filter and the GDPR filter in the directory. It suits a small team on a fixed budget less well, because core pricing needs a sales conversation and credits are metered.
Pricing
ZoomInfo's core packages have no published list price. The vendor says cost depends on features, the number of licenses and credit usage, and its sales team sets payment frequency. The GTM.AI route is published: a new account gets 1,000 data credits and 1,000 AI credits once at signup with no credit card, and credits expire 12 months after they are granted. After that, top-up packs start at $20, AI credits cost $0.05 each with no volume tiers, and one data credit covers one company, contact or intent record. The vendor's worked example prices the enrichment of 500 CRM leads at $215, about $0.43 a record, and a limited launch offer takes 70% off the first data credit purchase. Search, lookup and find-similar calls cost nothing.
For the quote-only packages, Vendr's anonymised contract data puts the median buyer at about $33,500 a year, with contracts from roughly $7,240 to $156,042, and says buyers saved about 22% on average. Treat that as a third-party estimate read in October 2026, not a list price. Vendr also lists overage fees and paid add-ons such as intent data as common extras. For a published per-seat comparison, see Apollo, which has a free plan.

Key Features
- Contact and company database: A searchable company and contact database with 135M+ verified phone numbers, 120M+ direct dials and 200M+ verified business emails, all figures the vendor reports itself.
- Buyer intent and account signals: Buyer intent signals, website visitor identification, champion tracking, job posting changes and breaking account alerts sit on the Copilot tiers, with real-time and custom intent on Copilot Enterprise.
- GTM Studio enrichment: Queries 25+ data sources at once, returns the highest-confidence match instead of the first hit, and can start workflows when a buying signal fires; the vendor says the waterfall carries no extra charge for customers.
- GTM.AI for agents: API, CLI and MCP access that works with Claude Code, Codex, Perplexity and other MCP clients; search and lookup are free, enrichment spends data credits and research spends AI credits.
- Context agents: Account Research, Contact Research, Conversation Intelligence and Signals agents return briefings for one account or contact, and most research calls cost 5 to 15 AI credits.
- Chorus conversation intelligence: Analyses calls, meetings and email alongside CRM and intent data to surface requirements, objections, commitments and next steps.
- Marketing audiences and ads: Marketing Demand and ABM packages add dynamic audiences, retargeting and the ZoomInfo Display Network, with 25 intent topics at Demand, 100 at ABM Lite and unlimited at ABM Enterprise.
- CRM and workflow integrations: The package pages list Salesforce, HubSpot, Marketo, Eloqua, Outreach and Salesloft, and press releases add native n8n and ClickUp links through GTM.AI.
Pros
- G2 shows 4.5 out of 5 across 9,188 reviews of its GTM Workspace listing, read on 19 October 2026.
- The vendor security page reports SOC 2 Type II coverage plus four ISO certifications, including ISO/IEC 42001 for AI management.
- Search and lookup stay free on GTM.AI even when credits run out, so an agent can explore the database without spending anything and pay only when it enriches or researches.
- One vendor covers contacts, buying signals, conversation analysis and an agent-facing API, which can replace several smaller subscriptions.
Cons
- Core packages have no published price, so the real cost cannot be checked on the vendor site and the only outside figure here is a third-party estimate.
- Credits are metered, and Vendr describes overage fees as a common extra, so heavy exporters can overshoot a contracted allowance.
- MCP cannot draw on the recurring monthly credits that some older subscriptions carry; it needs bulk data credits, so an existing customer may have to ask an admin to enable them.
- Vendor pages disagree on scale: the pricing page says 35,000+ companies, its own FAQ says over 30,000 customers, and a banner says 250 million users.
- Texas treats ZoomInfo as a data broker, and the privacy rules of each market still apply to anyone who contacts people from its data.
Data Handling
- Compliance
- SOC 2 Type II; ISO 27001; ISO 27701; ISO 27017; ISO/IEC 42001:2023 (all from the vendor security page); a TRUSTe GDPR practices validation letter and an independent CCPA readiness validation letter (from the vendor privacy page)
Frequently Asked Questions
How much do you pay for ZoomInfo?
The main platform cannot be priced from the website, because ZoomInfo publishes no price for its Professional, Copilot or marketing packages and builds the quote from licenses, features and credits. Vendr reports a median of about $33,500 a year across contracts it has seen, which is an outside estimate. The only published rates are on GTM.AI: $20 minimum top-ups, $0.05 per AI credit and a $215 example for a CRM enrichment batch.
What do you get on ZoomInfo's free tier?
GTM.AI gives a new account a one-time grant of 1,000 credits of each type, data and AI, with MCP, API and CLI access for up to 5 apps. Search, lookup and find-similar stay free afterwards, but enrichment and AI research pause until you top up. The no-recharge guarantee for re-enriching a record, called Records Under Management, is an Enterprise benefit and not part of the free allowance. The vendor's about page lists a free ZoomInfo Lite plan, and the pricing page offers a free trial request for the main packages, but neither states its limits.
Which tools compete with ZoomInfo in 2026?
ZoomInfo names Apollo, Cognism, Lusha, Clay, 6sense, Demandbase, Dun & Bradstreet and Gong. On HokAI, Apollo is the cheaper starting point with a free plan, and Clay is a workflow table that pulls from many providers. Gong is the comparison for Chorus call analysis, not for the contact data.
Is ZoomInfo better than Apollo?
ZoomInfo publishes no list price for its main packages while Apollo publishes per-seat prices that start with a free plan. Apollo bundles sequencing and a dialer in the same subscription; ZoomInfo leans on intent signals, conversation intelligence and an agent-facing API. ZoomInfo claims a larger database on its own about page, but that comparison is the vendor's. Pick ZoomInfo for enterprise data depth and buying signals, and Apollo when budget decides.
How long does it take to get going with ZoomInfo?
The quickest start is GTM.AI: sign up without a card, connect a client such as Claude Code with the plugin command, and ask for an account briefing, which usually costs 5 to 15 AI credits per the docs. For the full platform, the vendor describes a 90-day onboarding in four phases with a dedicated onboarding manager. Its pricing FAQ adds that CRM integrations typically carry a base cost and a minimum bulk credit purchase.
