What changes when the record becomes usable.

Leaders across market data, investing, and operations describe the difference a trusted record makes.

“The first solution truly built for market data teams.”
“PostSig doesn’t just extract information; it interprets agreements in context and highlights risks that generic legal systems overlook. For market data teams, often under-resourced and underfunded, this is the first solution truly built for them.”
Sheena Clark
Managing Director, UNA Data Group
“Performance-ready insight from what is buried in contracts.”
“PostSig is building what every enterprise will need in the AI era: a system of intelligence that activates what’s buried in contracts and turns it into performance-ready insight.”
Nick Adams
Managing Partner, Differential Ventures
“Faster, more reliable decisions.”
“PostSig surfaces the contract details we used to hunt down manually, helping us identify potential issues, make informed decisions, and stay on top of renewals and risk. It’s made our process faster and more reliable.”
Gary Glasser
Managing Director, Data Science, Birch Hill Equity Partners
“Direct, real-time visibility.”
“PostSig has fundamentally changed how we manage vendor agreements. Our clients now have direct, real-time visibility into their contracts, saving us time and improving efficiency across the board.”
Chris Petrescu
CEO, CP Capital
“Deep understanding of market data contracts.”

It is about execution that keeps rights and control aligned as things change. Investor Rights Intelligence reflects exactly where this market is going.”
Nick Adams
Managing Partner, Differential Ventures
