Supio

What It Does

Supio is a Seattle-based AI platform for personal injury and mass-tort litigation. It helps plaintiff firms organise, analyse, and prepare cases — ingesting and structuring large volumes of case data such as medical and billing records to support case preparation. It integrates with case-management systems including Litify and SmartAdvocate, and with Westlaw.

What We Found

Supio raised a $25M Series A (led by Sapphire Ventures, announced August 2024) and a $60M Series B in May 2025, again led by Sapphire with Mayfield and Thomson Reuters Ventures participating — bringing total funding to roughly $91M. It reports 4x ARR growth since emerging from stealth and was about a 100-person company at the Series B, with plans to roughly double headcount. Thomson Reuters has a published partnership with Supio for personal injury firms. Coverage appears in LawSites, GeekWire, and Maginative.
