Summize
Embedded contract lifecycle management that puts legal intelligence inside Word, Outlook, Teams, and Slack.
About
Summize is a Manchester-based AI contract lifecycle management platform built for in-house legal teams. Instead of asking the business to adopt a new tool, it embeds contract intelligence into the tools people already use: Microsoft Word, Outlook, Teams, SharePoint, Slack, Gmail, Salesforce, and HubSpot. Its architecture has three layers: a Knowledge Base that accumulates the legal team's knowledge, an Operations layer running the full contract lifecycle, and Summize Intelligence Agents (SIA) that surface answers across the business. The vendor says implementation runs in 3-4 week sprints with full rollout in 12 weeks or less.
The company secured a $50 million investment in January 2026 from Kennet Partners and Federated Hermes Private Equity alongside existing backers Maven Capital Partners and YFM Equity Partners, after what it describes as five consecutive years of ARR growth above 100 percent. Customers named by the company include Revolut, AMC Networks, Groq, SHL Medical, and Kroenke Sports & Entertainment. Pricing is quote-based for legal teams, so smaller companies should confirm fit before the demo process.
