In early June 2025, Definely, the UK-based legal tech innovator, secured a $30 million Series B funding round. This significant investment is set to drive Definely’s mission to integrate artificial intelligence (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 investors including Octopus Ventures and The Raine Group.
The Founders’ Origin Story
Definely’s story began in 2017 when co-founders Nnamdi Emelifeonwu and Feargus MacDaeid—then colleagues at Freshfields—faced a unique challenge. Feargus, who is registered blind, struggled to navigate complex legal contracts without losing his place.
Nnamdi asked himself: Could a simple interface help lawyers stay anchored while exploring definitions and clauses? This question sparked the creation of a tool that not only improved accessibility for visually impaired lawyers but also enhanced efficiency for the entire legal profession.
Building Definely’s Productivity Suite
Today, Definely offers a powerful suite of four integrated tools designed to streamline contract creation before publication:
- Draft: Enables lawyers to explore definitions and clauses inline, without breaking their reading flow.
- Vault: Provides a one-click clause library for easy insertion of precedents.
- Proof: Automates checks for cross-references, grammar, and logical consistency.
- PDF: Extracts and analyzes terms from scanned contracts.
Definely has also introduced an “agentic AI” system called Enhance, which integrates directly with Microsoft Word. This system coordinates multiple AI tools to draft, proofread, and optimize documents, serving as an intelligent legal assistant.
Rapid Growth and Expansion
Definely’s growth has been impressive. The company’s Annual Recurring Revenue (ARR) nearly tripled in 2024, and it now serves over 100 law firms and corporate legal teams. Its clientele includes top-tier Magic Circle and White Shoe firms, as well as major corporations like BT Group and Deloitte.
The United States now contributes 30% of Definely’s revenue. Since launching in 2020, the company has grown to 84 employees and expects to surpass 100 team members by late 2025.
Why the $30 Million Series B Matters
The Series B funding brings Definely’s total capital raised to $40 million, building on its previous $7 million Series A in May 2024.
This investment will support:
- Accelerated AI product development, including improvements to the Enhance system.
- Geographic expansion into the U.S., with new leadership and key relocations to the East Coast.
- Disciplined, capital-efficient growth, with a focus on sustainable scaling.
Revaia’s Partner Morgan Kessous praised Definely’s leadership in vertical AI for legal workflows and noted this is Revaia’s first UK investment, marking a key milestone in their European strategy.
A Vision Rooted in Accessibility and Efficiency
For Emelifeonwu, this funding is also a personal milestone.
“From a two-bedroom council flat to a $30 million Series B,” he said, reflecting on the barriers faced by underrepresented founders in Europe.
Beyond the funding, the raise validates Definely’s core purpose: building human-first AI tools to solve real legal workflow problems—not just riding the wave of AI trends.
Agentic AI: Reimagining Legal Workflows
Definely’s co-founders see the Enhance system as part of a broader industry shift toward agentic AI—software agents that manage specialized tasks in tandem, freeing legal professionals to oversee and make final decisions.
Feargus compares this to the Ford assembly line model:
“Agentic AI will be our workforce,” he explained, managing research, proofing, drafting, and review tasks, while lawyers maintain quality control.
What’s Next for Definely
With fresh funding in place, Definely is expanding its U.S. operations, appointing a new General Manager and planning to establish a physical presence in the U.K. and on the U.S. East Coast.
The company is also preparing new product releases that will further develop its agentic AI system, aiming to deliver even greater efficiency and accuracy to legal teams worldwide.
Conclusion: Focused Innovation Driving Transformation
Definely’s journey, born from a problem-solving partnership, now represents a global effort to transform legal productivity. In an industry traditionally resistant to change, Nnamdi Emelifeonwu and Feargus MacDaeid have proven that purpose-driven AI, designed to solve specific user challenges, can accelerate meaningful transformation at scale.
