Manchester digital contract management specialist Summize has successfully closed a $50 million investment round to accelerate its next phase of growth.
The new investment included participation from existing investors Maven Capital Partners and YFM Equity Partners, and also welcomed new specialist tech investment firm Kennet Partners and global investor, Federated Hermes Private Equity. The funding will enable further expansion of product capabilities, team, and customers globally.
The new funds follow five consecutive years of more than 100% ARR growth as Summize has scaled globally. In the last six months, from July to December 2025, it grew customer bookings by 92% and increased ARR by 97% YoY for the same period. It also expanded its US footprint with a new office in San Diego, announced in late 2025 to support the 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 benefiting from Summize’s CLM solution include Revolut, AMC Networks, SHL Medical, Clearscore, Sigma, Matillion, Modern Milkman and Groq, as well as numerous U.S. professional sports teams in the NBA, MLB and NFL.
Summize helps in-house legal teams manage contracts within popular software applications, including Microsoft Word, Outlook, Microsoft Teams, Slack, Salesforce, and HubSpot, enabling maximum efficiency, accuracy, and speed.
Built on its own CLM platform and using agentic AI, its technology applies legal context to ensure accuracy and trust in the contracting process. It also leverages AI to extract insights and knowledge from financial documents, compliance materials, handbooks, and regulatory content, surfacing important information in the right tools at the right time.
Tom Dunlop, CEO and co-founder of Summize (pictured), said: “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.”
Mike Clarke, partner at Leeds-based YFM Equity, added: “The Summize AI-powered experience offers a sophisticated approach to contracting that legal teams are easily adopting and using daily. Customers experience an incredible ROI in a short amount of time and benefit from the embedded experience of Summize within their existing collaboration tools. In addition, Summize’s strong foundation in AI and its ability to contextualize knowledge are designed to scale beyond core CLM use cases and into other areas of a company’s business, making this a strategic AI investment that scales beyond legal.”
Jeremy Thompson, partner at fellow long-term investor Maven Capital, said: “The Summize approach to innovation, its strong leadership team, and impressive company culture make it a strong investment. From its roots in summarizing contracts, the company has expanded its capabilities rapidly to become a cutting-edge Contract Lifecycle Management solution that has attracted global clients. With an exciting roadmap and big, future ideas, we’re looking forward to the next phase of growth and continued success with Summize.”
