In early June 2025, Definely, the UK-based legal tech innovator, secured a $30 million Series B funding round, propelling its mission to infuse AI into legal drafting and contract review workflows. The round was led by growth investor Revaia, with participation from Alumni Ventures, Beacon Capital, Clio, and existing backers including Octopus Ventures and The Raine Group
The Founders’ Origin Story
The catalyst for Definely emerged in 2017 when co-founders Nnamdi Emelifeonwu and Feargus MacDaeid—then colleagues at Freshfields—addressed a practical challenge: how to help a visually impaired lawyer navigate dense legal contracts efficiently. Feargus, registered blind, struggled to jump between terms and clauses without losing context. Nnamdi recalled asking himself: Could a simple interface feature help lawyers retain their place while exploring definitions? This question led them to build a tool that improved accessibility and served the entire legal profession.
The Rise of Definely’s Productivity Suite
Today, Definely offers a suite of four integrated tools designed to streamline the pre-publication stages of contract creation:
- Draft: Allows lawyers to explore definitions and clauses inline, without disrupting their reading flow.
- Vault: A one-click clause library to insert precedents directly into documents.
- Proof: Automates consistency checks—pinpointing cross-references, grammar, and logical inconsistencies.
- PDF: Enables extraction and analysis of terms from scanned contracts
Definely recently debuted an “agentic AI” system named Enhance. This feature integrates with Microsoft Word and co-ordinates multiple AI tools to draft, proofread, and optimize documents—effectively acting as an intelligent assistant.
Growth by the Numbers
Definely has experienced rapid expansion: its Annual Recurring Revenue (ARR) nearly tripled in 2024, and today it serves over 100 law firms and corporate legal teams, including Magic Circle and White Shoe firms along with multinational corporations like BT Group and Deloitte . Notably, the United States now accounts for 30% of the company’s revenue. The company has grown from its 2020 launch to 84 employees, with expectations to surpass 100 staff by late 2025
Why the $30 Million Series B Matters
This new funding brings Definely’s total capital raised to $40 million, marking a major escalation from its $7 million Series A in May 2024. The fresh investment will support:
- Accelerated AI product development, including enhancements to the Enhance system.
- Geographic expansion into the U.S., including hiring local leadership and relocating key employees to the East Coast
- Investment in capital-efficient growth, with CEO Emelifeonwu emphasizing a disciplined approach rather than reckless scaling.
Revaia’s Partner Morgan Kessous praised Definely’s leadership in vertical AI for legal workflows and noted that this Series B marks Revaia’s first UK investment—a key milestone in their European strategy
A Vision Rooted in Accessibility and Efficiency
For Emelifeonwu, the funding also represents breaking barriers: “From a two-bedroom council flat to $30 million Series B,” he said, reflecting on challenges facing underrepresented founders in Europe. But more than capital, this raise validates Definely’s core mission: human-first AI tools built to solve deep workflow problems, not to experiment with trendy buzzwords.
Reimagining Legal Workflows with Agentic AI
In interviews, co-founders describe Enhance as part of a broader shift toward “agentic AI” — software agents that handle specialized tasks in concert, freeing human professionals to act as orchestrators. Feargus compares this to Ford’s assembly line model: “Agentic AI will be our workforce,” handling research, proofs, drafting, and review, while lawyers oversee quality and final judgment
What Comes Next
Alongside its new funding, Definely is increasing its presence in the U.S., with a newly appointed General Manager and plans for a physical presence in both the U.K. and East Coast. The company also has a clear roadmap for future product releases—each building on the agentic system to drive even greater efficiency and accuracy for legal professionals
Conclusion: Transformation Through Focused Innovation
Definely’s journey—driven by a problem first identified through a friendship—now reflects a powerful story of lateral thinking and strategic scaling. With its latest funding, the company is poised to redefine legal productivity globally. In an industry often slow to embrace change, Nnamdi Emelifeonwu and Feargus MacDaeid have not only introduced breakthrough tools, they’ve proven that purpose-built AI, rooted in real user challenges, can accelerate transformation at scale.
