PostSig Raises $4.1 Million to Power AI-Native Intelligence Layer for Business Documents
Summary
PostSig raised $4.1 million in seed funding led by Differential Ventures, with several other venture firms participating. The company builds an AI-native platform that turns signed business agreements into live intelligence about obligations, risks, rights, costs, and renewals. PostSig focuses first on capital markets, where firms need tighter control over vendor risk, compliance, and contract value. The company says it has already managed more than $50 million in contract value across hedge funds, private equity firms, and asset managers. It plans to expand product capabilities, enter adjacent verticals, and scale go-to-market efforts.
