Mattermark vs PrivCo

Mattermark helps users find, prospect, and track fast-growing companies and investors. Company profiles cover more than 80 fields, including geography, industry, revenue, personnel, funding, and employee growth; the service also monitors changes in team size, web traffic, and media mentions. Users can search, filter, and sort company information, then follow organizations with saved searches, custom lists, and news notifications. Mattermark says it draws information from millions of news articles and websites daily using machine learning, web crawlers, primary sources, and natural language processing, with in-house analysts verifying data daily. Its Salesforce integration syncs company information into leads and other objects and supports triggers and actions on data fields. Excel, Google Sheets, an iOS app, and a Chrome extension are also listed as access or integration options. The API offers REST and GraphQL access to company and investor data, including details, news, similar companies, and funding events; its trial includes 100 free API calls. Pricing includes free iOS access, paid options from $49/user/mo, and other plans with separate terms.

PrivCo provides intelligence on private companies, including financial estimates, ownership, contacts, funding and deal activity. Search filters include industry, location, revenue, EBITDA and ownership; users can save searches, create watchlists and monitor changes. Revenue, EBITDA and company-value estimates are presented with a range, update date, confidence level and supporting information. PrivCo says its main focus is U.S. private companies with annual revenue above $1 million, and that more than 85% of its coverage is bootstrapped or family-owned without outside VC or PE funding. The company describes combining licensed datasets, filings, court records, news, digital footprints and proprietary research, with automated checks and analyst review. Company information can be exported for outreach, internal review, market mapping and analysis. REST API and MCP access are documented, including connectors for Claude, ChatGPT and Microsoft Copilot; API access requires an enabled account. Free accounts provide AI-powered search but omit profiles, contacts, watchlists and exports. A seven-day List Builder trial has specified profile, search and contact-view limits and excludes exports and classic search tools.
