SignSplit emerges from stealth with a $400M 'strategic seed' commitment at $1B to let people license data to AI labs

SignSplit, a Delaware public benefit corporation founded in 2024, launched with what it calls a $400M strategic seed round at a $1B valuation from W Group, a consortium of 11 blockchain-focused fintech firms, which was the sole investor. The platform lets individuals and institutions digitally sign data, creative work and likeness rights, pool them, and get paid when AI developers license them, with a verification layer that tracks consent and usage rights. The company has not said how much of the $400M is immediately available cash versus strategic resources delivered over a multi-year partnership, so the headline figure should be read with that caveat. Consented, provenance-tracked training data is becoming its own asset class as labs face licensing pressure.
