Frontrun helps venture investors, analysts and scouts find startups before their funding rounds are public. It continuously watches the follow lists of more than 5,000 tracked investors, analysts and operators on X, and surfaces a company when several of them start following it within a short window. Each signal is dated, so users can see how early a company was spotted. A second layer detects founders building in stealth from profile changes, career moves and investor attention. Users get a live feed, a daily report, sector filters, watchlists with founder and funding enrichment, and outreach lists for X and LinkedIn. A REST API and an MCP server let AI agents run deal sourcing workflows on the same data.
