Definely raises $30m Series B

June, 2025 – AI-powered legal tech company, Definely, has raised $30 million in Series B funding to accelerate its global expansion and AI product roadmap.

• Definely is headquartered in London with over 80 employees globally
• The company has gained strong traction in the US, which now accounts for 30% of its revenue
• This new investment follows their $7m Series A round 12 months ago

The round is led by growth investor Revaia, alongside Alumni Ventures, Beacon Capital, and legal tech giant, Clio. Early investors, including Cornerstone VC, Octopus Ventures, Zrosk, The Raine Group have also participated in the round.

Launched in 2020 by Nnamdi Emelifeonwu and Feargus MacDaeid – who worked together at Freshfields – Definely was born from lived experience, including that of co-founder MacDaeid, who is registered blind after being diagnosed with a degenerative eye condition at age 11. Throughout his life, he consistently faced challenges in accessing information efficiently, overcoming these through the use of different types of technology. His unique professional experience has fundamentally shaped Definely’s product.

Definely almost tripled its annual recurring revenue (ARR) in 2024, following a rapid increase in customer growth. Now trusted by over 100 in-house legal teams and private practice firms, with a high degree of engagement from all users, thanks to the interoperability of the products with existing workflows. Its customers include top Magic Circle and White Shoe firms, including A&O Shearman, Slaughter and May, DLA Piper, and Dentons, and in-house corporate counsel for blue-chip companies such as BT Group, Deloitte, and P&O Cruises.

Definely has gained strong traction in the US market, which now accounts for 30% of its revenue.

The latest fundraise will support further expansion, with key employees moving to the East Coast and where Definely has recently appointed a US-based General Manager. The funding will also be used to further develop new and existing products with a goal of superpowering legal workflows. Last month, Definely announced the launch of its multi-agent AI system, ‘Enhance’.

Definely is built for lawyers working under pressure on complex, high-stakes deals. It meets lawyers where they are by integrating within Microsoft Word, rather than operating on a separate system or platform. The products allow lawyers to retain contextual understanding of legal documents by instantly surfacing relevant information within and across contracts. Overall, Definely expects customers to see at least a 40% speed improvement in their workflows using its latest AI product, Enhance, versus a traditional manual approach.

Nnamdi Emelifeonwu, Co-Founder & CEO of Definely commented

This latest investment round is a testament to the hard work of an incredible team and the trust our customers have placed in us.

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.

Edwin Appiah, Partner at Cornerstone VC, said

Definely is well on its way to becoming the preferred legal tool for magic circle lawyers and in house legal teams.

This new capital injection will help to further embed their consequential reasoning engine across their product suite, helping legal teams understand how edits impact entire contracts.

This is a bold step toward redefining the legal workflow and we’re proud to back a team that’s building a truly automated legal companion.
