Sentient, an open-source artificial intelligence development platform with Polygon co-founder Sandeep Nailwal as one of its core contributors, has raised $85 million in a seed funding round.

Peter Thiel's Founders Fund, Pantera Capital and Framework Ventures co-led the mega round, Sentient said Tuesday. Other investors in the round included Ethereal Ventures, Robot Ventures, Symbolic Capital, Delphi Ventures, Hack VC, Arrington Capital, HashKey Capital, Canonical Crypto and Foresight Ventures.

Sentient began raising funds for the seed round in March of this year and closed it in May, Nailwal told The Block in an interview. He declined to comment on the structure of the round and valuation.
