SignSplit Raises $400M Seed Round, Valued at $1 Billion
Data-rights startup SignSplit has closed a $400 million seed round at a $1 billion valuation, targeting the growing market for licensed human data.
SignSplit, a Wilmington, Delaware-based technology startup, has secured a $400 million strategic seed round at a $1 billion valuation, the company announced October 5, 2026. The financing ranks among the largest seed-stage raises on record, signaling strong investor appetite for platforms built around human data rights.
The company's platform allows individuals and institutions to protect, license and monetize their data, creative work and personal likeness. SignSplit positions itself as a connector between data owners and the rapidly expanding demand for verified, real-world human data from artificial intelligence developers, research organizations and media companies.

The raise comes as regulatory and public scrutiny of how AI companies source training data has intensified globally. Platforms that offer consent-based, compensated data licensing have emerged as a potential alternative to the scraping practices that have drawn legal challenges from authors, artists and public figures. SignSplit's model appears designed to capitalize directly on that shifting landscape.
The size of the seed round is notable even by the standards of a frothy AI investment environment. A $400 million raise at the earliest stage of company formation suggests institutional backers are placing early, high-conviction bets on infrastructure plays that sit between data creators and AI consumers — a layer of the market that has attracted growing strategic interest.
