ZoomInfo

ZoomInfo brings B2B contact and company data together with tools for prospecting, marketing, revenue operations, and customer success. It is most compelling for teams coordinating several stages of a go-to-market process; teams that only need occasional contact lookups may find its breadth and custom-priced plans excessive.

Overview

The platform combines prospecting, buyer intent, account insights, lead routing, CRM enrichment, and sales workflow automation. That scope can help sales and marketing teams work from shared data through to follow-up, rather than assemble a separate tool for each step. ZoomInfo describes its coverage as 500M+ contacts and 100M+ companies; its contact database size is also given as 321,000,000. Those figures express different coverage measures, so buyers should check which applies to their intended use.

Founded as DiscoverOrg in 2007, the company acquired ZoomInfo in 2019 and adopted that name. The company is headquartered in Vancouver, Washington, USA.

Key features

Direct-dial data, buyer intent, and technographic filters give prospecting teams ways to narrow searches and prioritize accounts beyond basic company and contact profiles. Account insights and intent data can guide outreach, while lead routing, CRM enrichment, and workflow automation support what happens after a prospect is identified. This is a strong fit for teams that need the data and operational steps together, but may be unnecessary overhead for a team focused only on contact lookup.

ZoomInfo describes AI tools for account research, meeting preparation, deal prioritization, and coordinated go-to-market plays. It integrates natively with Salesforce, HubSpot, and Microsoft Dynamics 365, and offers 120+ integrations. Its MCP server connects Claude, ChatGPT, and custom agents to ZoomInfo data. These options matter most to organizations already using those systems or building AI-assisted workflows; they offer less reason to choose ZoomInfo if a team does not need connected workflows.

Support is available through the Help Center and by phone, while ZoomInfo University offers role-based courses and certifications. A structured 90-day onboarding program covers planning, technical implementation, education, and adoption. That can support a substantial rollout, though the program's length suggests a larger implementation commitment than a lightweight lookup tool.

The Trust Center lists ISO 27701, ISO 27017, ISO 27001, and SOC certifications among its affiliations and certifications. ZoomInfo says it processes professional contact data under GDPR's legitimate-interest basis and honors data subject rights. These are relevant considerations for organizations evaluating privacy and security practices, though buyers should assess their own compliance requirements.

Pricing

ZoomInfo offers a permanent free plan and paid plans with custom pricing. Paid-plan prices require a request, so buyers should establish cost and terms before comparing plans against a fixed budget.

• ZoomInfo Lite: free. The permanent free plan requires no credit card and no commitment, making it a low-friction way to start. The free-plan description gives no quota, so teams should confirm whether its limits fit their regular use.
• ZoomInfo Professional: custom pricing. It includes contact and company profiles, search and exporting, mobile numbers and business email, a Chrome extension, mobile app, and standard support. It suits teams primarily seeking contact data and prospecting tools; it does not include the buyer-intent and workflow additions described for higher tiers.
• Copilot Advanced: custom pricing. It adds buyer intent, website visitors, buying group filters, and automated workflows to Professional features. These additions are useful when account prioritization and workflow automation are central needs.
• Copilot Enterprise: custom pricing. It adds real-time buyer intent, advanced workflows and reporting, a dedicated customer service manager, and white-glove onboarding to Copilot Advanced. The extra service and capabilities make it the tier for organizations needing more support and advanced execution, rather than basic prospecting.
• Marketing Demand: custom pricing. It includes 75K credits, 25 intent topics, audience targeting, CRM and MAP integrations, and a dedicated onboarding manager. Its credit and topic allowances make it a marketing-focused option, but teams should check whether those caps match their campaign needs.
• ABM Lite: custom pricing. It includes Marketing Demand features, 100 intent topics, up to 10 active campaigns, and 10K accounts on the ZoomInfo Display Network, plus a dedicated delivery and campaign manager. Those limits suit a bounded account-based marketing program; they may constrain teams running more campaigns or targeting more accounts.
• ABM Enterprise: custom pricing. It adds 150K credits, unlimited intent topics, campaigns, and accounts on the ZoomInfo Display Network, and predictive account scoring to ABM Lite features. It is the broadest ABM option for programs needing scale, but the custom price makes budget fit a key consideration.

The free trial includes core platform features with usage limits, requires no credit card, and typically lasts 7 days, with terms varying. It can help teams assess the platform, but a short, limited trial may not be enough to validate sustained usage or a larger rollout.

Platforms

ZoomInfo is available through the web, an API, and an extension. The Professional plan also includes a mobile app, giving prospecting teams a stated mobile option alongside browser and integration-based access.

Who it's for

ZoomInfo is best suited to sales, marketing, revenue operations, and customer success teams that need company and contact data connected to prospecting, intent, enrichment, routing, and workflow tools. Its upper plans are particularly relevant to teams running coordinated sales or account-based marketing programs. A small team needing only occasional contact details should weigh the custom-priced tiers and broader implementation against that narrower need.

Pros and cons

• Pro: Contact and company data sit alongside intent, enrichment, routing, and automation, which can support a connected go-to-market process.
• Pro: Native Salesforce, HubSpot, and Microsoft Dynamics 365 integrations, plus 120+ integrations and MCP connections for Claude, ChatGPT, and custom agents, give teams several ways to connect their workflows.
• Pro: The permanent free plan requires no credit card or commitment, and the trial also requires no card, so teams have a way to begin without an immediate purchase.
• Con: Paid plans use custom pricing, making it harder for buyers to judge budget fit before contacting the company.
• Con: The trial is usage-limited and typically lasts only 7 days, which can restrict evaluation of sustained or broader use.
• Con: Several paid tiers have explicit credit, topic, campaign, or account limits; teams with larger programs may need the higher-priced, custom-quoted options.

Alternatives

Consider Apollo if a self-serve free plan is important: its Free plan provides 900 credits per seat per year, granted monthly, plus two sequences, API access, and one intent topic. Choose Lusha if a smaller free allowance and a single included seat suit your needs; its Free plan provides 40 credits a month and requires no credit card.

People Data Labs is an alternative to consider when an API-centered product is the priority. Seamless.AI offers a free plan with one user and 50 credits. For a free plan with one user and 50 credits, consider LeadIQ; its Pro plan is $200 a month billed annually.

Lead411 offers a 7-day free trial with 50 free exports, while ContactOut has a free plan with 10 free credits and a Team / API option. Wiza is another option, with a free plan that includes 20 valid emails and five phone numbers.

Verdict

Choose ZoomInfo if your organization needs B2B contact and company data connected to sales, marketing, or account-based workflows, and can justify a custom-priced platform. Its breadth, integrations, and role-specific plans are the main reasons to pick it; the short, usage-limited trial and opaque paid pricing are the reasons to look elsewhere if you need a predictable cost or a simple contact lookup tool.
