Summize (legal tech) raises $50M growth round

Today we announce a $50 million investment to accelerate our next phase of growth. The new investment included participation from our existing investors – Maven Capital Partners and YFM Equity Partners – and welcomed new specialist tech investment firm Kennet Partners and global investor, Federated Hermes Private Equity. The funding will enable further expansion of our product capabilities, team, and customers globally.

The new funding follows five consecutive years of more than 100% ARR growth as we have scaled globally. In the last six months, from July to December 2025, we grew our customer bookings by 92% and increased our ARR by 97% YoY for the same period. We also expanded our U.S. footprint with a new office in San Diego announced in late 2025 to support our West Coast customer base, and a new, larger UK office in Manchester to support our global team headcount growth of 59% in the past year. Customers benefiting from our CLM solution include Revolut, AMC Networks, SHL Medical, Clearscore, Sigma, Matillion and Groq, as well as numerous U.S. professional sports teams in the NBA, MLB and NFL.
