Our verdict on StartupDB

StartupDB is a free web and API database for researching startups, investors, funding activity, people, sectors, and technology tags. It is intended for founders, investors, operators, researchers, and developers who need searchable startup ecosystem records without a paid plan. Company profiles, founder and people records, funding data, investor relationships, and advanced search are included, with 2,487 companies displayed on the official Companies page.

Its strongest fit is API-first research and structured discovery. Users can search company, investor, and people records; examine portfolio relationships and financing activity; and ask structured questions about rounds, investors, companies, sectors, and co-investors. The public JSON API provides access to startup and investor relationships, while the MCP server supports agent-based access. This makes StartupDB more useful for programmatic workflows and research tools than for teams seeking a broad, connected software ecosystem.

StartupDB keeps its scope focused on searchable startup data rather than ongoing monitoring or workflow management. The published product positioning does not include alerts or integrations, so it is better suited to on-demand research, relationship discovery, and data access than to automated tracking across connected business tools. Database coverage is labeled public beta and may change. Choose StartupDB if free company, funding, investor, and people data with API access meets the need; choose an alternative if alerts, integrations, or a broader operating workflow are central requirements.
