Summize, a provider of AI Contract Lifecycle Management (CLM) software, has announced it secured a $50 million investment to accelerate its next phase of global growth, product development, and team expansion.
The funding round saw participation from existing investors Maven Capital Partners and YFM Equity Partners, alongside new specialist tech investor Kennet Partners and global investor Federated Hermes Private Equity. This capital infusion is intended to support the company’s ongoing expansion of its product capabilities, team, and customer base worldwide.
The investment follows a period of consistent growth for Summize, which has achieved over 100% annual recurring revenue (ARR) growth for five consecutive years. In the latter half of 2025, from July to December, the company reported a 92% increase in customer bookings and a 97% year-over-year ARR growth for the same period.
Summize has also expanded its physical footprint, opening a new office in San Diego in late 2025 to support its West Coast clientele, and a larger office in Manchester, U.
K., to accommodate a 59% increase in its global team headcount over the past year. The company’s customer portfolio includes organizations such as Revolut, AMC Networks, SHL Medical, Clearscore, Sigma, Matillion, Groq, and several U.
S. professional sports teams in the NBA, MLB, and NFL.
Alex Taylor-Harris, Director at Kennet Partners, commented on the investment, stating, “Summize’s proven performance, clear market differentiation, and long-term vision for AI-powered contract management make it a disruptive CLM player in a crowded market.” He added that customers value Summize’s embedded approach, which integrates AI and CLM capabilities directly into tools they use daily.
Summize’s platform assists in-house legal teams by managing contracts within popular business applications like Microsoft Word, Outlook, Microsoft Teams, Slack, Salesforce, and HubSpot. Utilizing its CLM platform and agentic AI, Summize applies legal context to enhance accuracy in contracting. The software also leverages AI to extract insights from financial documents, compliance materials, handbooks, and regulatory content, delivering relevant information at appropriate times.
Jeremy Thompson, Partner at Maven Capital, highlighted Summize’s innovative approach and leadership, noting, “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.” Mike Clarke, Partner at YFM Equity, further emphasized the platform’s ability to provide significant return on investment quickly due to its embedded experience within existing collaboration tools.
Tom Dunlop, CEO and Co-Founder of Summize, articulated the company’s mission: “We founded Summize to make contracts easier to understand and the contracting process more efficient by complementing how modern teams work.” He stated that the new $50 million investment validates their distinct user experience and capacity to develop innovative AI solutions for legal and wider business functions, enabling continued scaling through focus on user experience, AI innovation, and team expansion.
Summize engaged Canaccord Genuity as its exclusive financial advisor for the transaction, with Squire Patton Boggs providing legal counsel and BDO offering finance and tax advice. The company, founded in 2018, is headquartered in Manchester, U.
K., with U.
S. offices in Boston and San Diego.
