Our Take
A competent product-market fit story, not a capability leap: Litera bought a working legal CRM, plugged it into Microsoft's stack, and is now counting existing users as a launch win.
Why it matters
Law firms spend heavily on client relationship intelligence. For firms already in Microsoft 365, staying within the same ecosystem reduces friction and data silos. The timing matters because Copilot integration is table stakes for enterprise software now.

General counsel or COO: audit your current CRM and data-entry friction in Outlook and Teams over the next two weeks to determine if Foundation 365's native integration saves staff time.
Litera Launches Foundation 365 Inside Microsoft 365
Litera has made Foundation 365, its AI-powered CRM platform for law firms, available across Microsoft 365, including Outlook, Teams, and Microsoft 365 Copilot. The product is built on Microsoft Dynamics 365.
Foundation 365 arrived at Litera through its acquisition of Peppermint Technology, a UK developer of legal-specific applications built on Microsoft technology. The platform was formerly called Peppermint Client Engagement.
The core function is straightforward: surface client and relationship data directly into Copilot so attorneys and business development professionals can identify which client relationships are strong, which need attention, and who within the firm is best positioned to make a given contact. Grant Hewlett, vice president of product for firm intelligence at Litera, framed it as "GrowthTech," a term the company uses to describe tools that deepen client relationships rather than simply track them.
Foundation 365 extends Litera's existing legal AI agent, Lito, which is already embedded in Outlook, Word, the web, and Apple iOS.
According to the company, five of the Global Top 10 Law Firms and more than 4,000 firms worldwide currently use Foundation 365 (company-reported). Litera also received the 2025–2026 Microsoft AI Business Solutions Inner Circle Award, which Microsoft awards to fewer than 1% of its global partner network.
The Real Story Is Distribution, Not Innovation
This is not a breakthrough in legal AI. Litera acquired a functioning product and redistributed it through Microsoft's channels. That is a sound business move, not a technical one.
The value for law firms lies in reduced context-switching. If you are already inside Outlook and Teams all day, having CRM data surface in Copilot saves the step of logging into a separate system. That saves time. It does not solve new problems or answer questions that existing legal CRMs cannot.
The Microsoft AI Business Solutions award signals that Litera is meeting Microsoft's baseline for partner quality, not that the product is singularly capable. Microsoft awards this to fewer than 1% of partners (company-reported), which sounds selective until you learn that Microsoft's partner network exceeds 700,000 members globally. Fewer than 1% of 700,000 is still thousands of companies.
The user count—5 of Global Top 10 and 4,000+ worldwide—is significant as evidence of existing traction. But these users were already using Foundation 365 (or Peppermint Client Engagement before the rebrand). The announcement is that they can now access it inside Microsoft 365, not that they are newly adopting it.
What Law Firm Leaders Should Do
If your firm uses Microsoft 365 extensively and your CRM system requires separate login workflows, Foundation 365 is worth a pilot. The integration savings are real if they eliminate redundant data entry or cut the time to look up a client relationship during a call.
If you already have a legal CRM deeply integrated with your firm's workflows (billing, matter management, document automation), the switch cost may outweigh the Outlook convenience gain. Audit your current friction points before evaluating.
The presence of five Global Top 10 law firms on the customer list is a relevant reference check. Request calls with one firm in your practice area to understand what they use Foundation 365 for and what they still handle outside Microsoft 365.
