FlareSight vs StartupDB

FlareSight turns SEC filings into startup funding information for investors, sales teams, recruiters and founders. The site says it tracks more than 127,000 startups and updates daily; most companies appear within 24 hours of filing, after prior-day filings are processed at 6am UTC. Funding amounts and filing details come directly from SEC filings, and each record links to its Form D. Users can filter activity by sector, stage and geography. Company profiles can include founder names, roles and LinkedIn profiles, while metadata such as sector and description is enriched from additional sources and verified where possible. Free accounts include all search filters, five profile views per day, one view-only watchlist and a weekly email digest. Starter costs $24 a month, billed $288 annually, and includes 30 monthly contact reveal credits, three watchlists, daily digests and AI-drafted email openers. Pro costs $80 a month, billed $960 annually, with 250 monthly contact reveals and API access. Contacts revealed on any plan can be exported to CSV.

StartupDB is a free database of startups, investors and people, organized around investment relationships and funding rounds. Company records can include funding dates, amounts, investor roles and source URLs, and facts link to sources for checking. Its data draws on reviewed public investor portfolio pages, public news, company and investor websites, and edits by staff, founders and investors. The database is available through a read-only MCP server and REST API, without an account or API key. The MCP server has six tools for searching investors, startups and people and retrieving individual records. The REST API provides GET endpoints for searches, individual records, investor portfolios and company funding activity, returning JSON. Both interfaces allow 120 requests per minute per IP address, with no daily cap. StartupDB says coverage is not complete, so a missing round or investor means only that the information is absent from the database. Dataset facts and compilation are licensed under CC BY 4.0 for commercial reuse with attribution; third-party logos, photos and site text are excluded. Founders and investors can claim and correct pages, and staff review reported issues. StartupDB says it was built at Workshop.
