About this site
UnannouncedVC Companies that just raised money and have not said so. A newly funded startup is hiring and buying; while the round is still quiet, nobody else is calling them. 73 of the 101 rounds filed in the last 30 days have no announcement anywhere: no press release, no news story, no funding database. The rounds that are announced show up here a median of 23 days before the news. 48% are still unannounced three months after the filing. 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.
