SignSplit, a startup that wants people to be paid when AI companies use their data, came out of stealth on October 5, 2026 with a $400 million seed round. The round comes from one backer, W Group, and values the two-year-old company at $1 billion, according to its announcement. The pitch is aimed at two groups: AI and robotics firms that need real-world human data, and the people who supply it.
What SignSplit sells
SignSplit lets people and institutions "protect, license and contribute their data, work and likeness," the company says. Likeness means a person's face, voice or appearance. Every contribution is meant to carry consent and a clear record of where it came from, known as provenance.
Forbes Italia describes the product as data infrastructure for licensing real-world human data to AI companies. It is built around what the company calls Data Pools and Research Pools, each shaped around a buyer's specific needs. Contributors supply real-world data, knowledge and skills.
AI and robotics companies, researchers and other organizations pay to use these pools. The people who contribute get paid in return. Forbes Italia says the system manages consent, provenance, rights and payment in one place. Neither source gives prices, contributor numbers or customer names.
What the $400 million actually is
This is not a typical cash round. W Group's commitment combines capital with a multi-year package of strategic resources for SignSplit's global rollout, the press release says. The announcement does not break down how much of that is cash.
W Group describes itself as a global fintech and technology group with more than 40 million users. Its founder and president, Volodymyr Nosov, explained the size of the deal. "The scale of our commitment reflects both how early we believe we are, and how important we believe these solutions are," he said in the release.
Who runs SignSplit
The company was founded in 2024 and is registered as a Delaware public benefit corporation, based in Wilmington. A public benefit corporation is a for-profit company that also commits in its charter to a stated social goal.
| Founder | Role |
|---|---|
| Alessandro Monterosso | Co-founder and CEO |
| Glib Denisov | Co-founder, executive chairman and chief product officer |
Monterosso began his career as a hospital ward nurse, Forbes Italia reports. He later founded PatchAI, which collected health data through an AI assistant. Alira Health acquired PatchAI in 2021.
"SignSplit provides solutions for a world where the boundary between human experience and technology is becoming increasingly fluid," Monterosso said in the announcement.
What this means for developers
If your team trains models on human data, consented sources are becoming a product category of their own. When you evaluate any data vendor, SignSplit included, ask for three things in writing. You need proof of consent for each record, a provenance trail you can audit, and license terms that cover your intended use.
Budget for paid data. A marketplace that pays contributors will charge buyers more than scraped data costs. In return, documented consent gives you an answer when regulators or rights holders ask where your training data came from.
Treat the headline number with care. A seed round that mixes cash with unnamed "strategic resources" from one backer says less about demand than a priced round led by several investors would. Watch for the first named customers, published prices and contributor numbers before you plan around the platform.
