In their own words
FlareSight
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.
