All of Dealroom’s data, over an API.
Dealroom maps the world's startups, investors, founders and funding. The API puts all of it — companies, people, rounds, valuations and signals — straight into your sourcing, scoring and product workflows.
Pull it over a REST API, query it in plain language through a hosted MCP server, or take it as a bulk data feed into your warehouse and CRM.
