CLM Summize Bags $50m, Claims 100% ARR Growth For 5 Years

Summize, a CLM company that started back in 2018 in Manchester, has raised $50m. The news comes as a number of other legal tech businesses have announced raises – or are about to – this week.

The new funding follows five consecutive years of ‘more than 100% ARR growth as the company has scaled globally’, they said.  

In the last six months, from July to December 2025, Summize grew its customer bookings by 92% and increased its ARR by 97% YoY for the same period, they added.

The company also expanded its US footprint with an office in San Diego, announced in late 2025 to support its West Coast customer base, and a new, larger UK office in Manchester to support its global team headcount growth of 59% in the past year.

Customers now include: Revolut, AMC Networks, SHL Medical, Clearscore, Sigma, Matillion, and Groq, as well as numerous US professional sports teams in the NBA, MLB, and NFL.

Tom Dunlop, CEO and Co-Founder of Summize, commented: ‘We founded Summize to make contracts easier to understand and the contracting process more efficient by complementing how modern teams work. This new $50 million investment underlines our differentiated user experience and ability to design innovative, trusted AI solutions for legal teams and the wider business. With the support of our new and existing investors, we will continue to scale the business by focusing on our intuitive user experience, ongoing AI innovation, and expanding our exceptional team to support our growing number of global customers.’
