SignSplit raises $400 million at $1 billion valuation to monetize personal data for AI

SignSplit PBC launched in October 2026 after securing a $400 million Series Seed funding round from sole investor W Group, valuing the startup at $1 billion. Led by CEO Alessandro Monterosso, SignSplit PBC provides infrastructure for 'signed data,' allowing individuals to protect, license, and monetize their personal data, likeness, and voices for AI training. The platform addresses growing regulatory demands for explicit consent under the EU AI Act and U.S. privacy laws, shifting the industry standard from data availability to verifiable user permission.
