Definely Funding News -UK LegalTech Firm Definely Secures $30M In Series B Round

This brings the company’s total funding to $40 million since its launch. Co-founder MacDaeid, who is registered blind due to a degenerative eye condition diagnosed at age 11, faced lifelong challenges accessing information. His journey has been key in shaping the company’s mission and product design.

Definely integrates directly into Microsoft Word, allowing lawyers to work seamlessly without switching platforms.

Its tools help legal professionals quickly access relevant information across documents, maintaining context and improving efficiency.

The company’s latest AI product, Enhance, is designed to boost legal workflow speeds by at least 40% compared to traditional methods.

In 2024, Definely nearly tripled its annual recurring revenue (ARR), driven by strong customer growth. Today, it is trusted by over 100 legal teams and law firms, including major names like A&O Shearman, Slaughter and May, DLA Piper, and Dentons, as well as corporate legal departments at BT Group, Deloitte, and P&O Cruises.

Definely is also expanding rapidly in the US market, which now contributes 30% of its total revenue—a strong sign of its growing international footprint.

 According to Nnamdi Emelifeonwu, co-founder and CEO of Definely: “As a business, we are deeply committed to building human-first products, leveraging generative AI not for the sake of it – but to solve real and tangible problems that lawyers face today. As a former lawyer myself, I witnessed some of these problems first-hand.

This funding will allow us to invest further in developing and integrating our products. We recently launched our first agentic product, ‘Enhance’, which has been well received by our customers, and have a series of further exciting features in the pipeline.”

The funding round includes new investors such as Revaia, Alumni Ventures, Beacon Capital, and Clio. Existing investors Octopus Ventures, Zrosk Investment Management, The Raine Group, and Cornerstone VC also joined the round.

Morgan Kessous, Partner at Revaia said: “We are proud to lead Definely’s Series B and support a company that is setting the standard for AI-powered legal technology.

With enterprise-grade products already live and gaining strong traction, Definely is now accelerating both its AI roadmap and international expansion - a journey we are excited to support.

The transaction is also marking our first investment in the UK since opening our London office, which is an important milestone for Revaia.”

Definely currently has a team of 84 employees and expects to grow beyond 100 in the second half of 2025.

The recent funding will support this expansion, including the relocation of key team members to the U.S. East Coast, where Definely has recently appointed a General Manager to lead its operations.
