How many venture rounds are never announced?
Startups file a notice when they raise, usually within weeks of the first sale. Announcing the round is optional. Across 2,294 venture-backed rounds filed since 2 January 2025 and checked on the web, 48% of those filed at least three months ago still had no public announcement.

How this was measured
Rounds are the offerings of Delaware corporations, not funds or vehicles, with a director who is named on a venture fund's filing. Each round is checked on the web for an announcement under the company's legal and brand names; a press release, news story or company or investor post about the round counts.
