UnannouncedVC

Companies that just raised money, before they announce it. A newly funded company is hiring and buying; once the round is out, everyone is calling them. UnannouncedVC follows venture-backed startups through the notices they file when they sell shares. A notice is due within weeks of a round's first sale, so it often comes out before the round is announced, or is the only public record of it. Every raise here has an investor from a venture firm on the company's board, and every one filed since 2025 is checked on the web for an announcement.
