PostSig, an AI platform that turns static business contracts into real-time intelligence, has raised $4.1M in a seed round led by Differential Ventures with participation from Tandem Ventures, Denver Ventures, Frontier VC, Unbound Ventures, and SaaS Ventures. The platform ingests agreements such as licensing and vendor contracts, interprets clauses, and builds a live network of obligations, rights, risks, and costs—helping firms spot billing issues, manage compliance, and prepare for renewals. In its first two sales quarters, PostSig has supported over $50M in contract value across hedge funds, private equity firms, and asset managers. The new funding will be used to expand product capabilities, target additional verticals, and scale go-to-market operations.
