SignSplit launches from stealth with $400M seed at $1B valuation

A single fintech backer funded the entire round, betting that data consent and provenance becomes core AI infrastructure.

• SignSplit PBC emerged from stealth with a $400 million strategic seed financing from W Group that values the company at $1 billion.
• SignSplit runs a 'signed data' platform letting people and institutions license their data, creative work and likeness to AI, robotics and media companies in exchange for compensation.
• W Group, a fintech ecosystem serving more than 40 million users across 150 countries, is the sole investor and becomes SignSplit's anchor strategic partner.
• The financing blends cash with a multi-year package of strategic resources for global rollout, though the companies have not disclosed the cash-versus-resources split or funding timeline.
• Founded in 2024 as a Delaware public benefit corporation by CEO Alessandro Monterosso, previously co-founder of clinical-data startup PatchAi, and CPO Glib Denisov, SignSplit has not disclosed customers, revenue or deployments.
• The deal signals a strategic investor is willing to make one of the largest seed-stage bets on record that consent and provenance, not just raw data volume, will become a priced layer of the AI supply chain.
