Definely Raises $30m Series B to Transform Legal AI Workflows
In June 2025, UK-based legal tech company Definely secured $30 million in a Series B funding round. This capital injection will accelerate the integration of AI into legal drafting and contract review. The round was led by growth investor Revaia, with contributions 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 real challenge. Feargus, who is registered blind, found it difficult to move between terms and clauses in legal contracts without losing context. Nnamdi asked a simple question: Could an interface feature help lawyers keep their place while exploring definitions? This question led to building a tool that not only improved accessibility but also aimed to support all legal professionals.
The Rise of Definely’s Productivity Suite
Definely now provides four integrated tools designed to streamline contract creation before publication:
- Draft: Enables lawyers to explore definitions and clauses inline without breaking reading flow.
- Vault: A one-click clause library to insert precedents directly into documents.
- Proof: Automates consistency checks by identifying cross-references, grammar, and logical issues.
- PDF: Extracts and analyses terms from scanned contracts.
Recently, Definely launched “Enhance,” an “agentic AI” system that integrates with Microsoft Word. Enhance coordinates multiple AI tools to draft, proofread, and optimize documents, acting as an intelligent assistant for legal professionals.
Growth by the Numbers
Definely’s Annual Recurring Revenue (ARR) nearly tripled in 2024. The company now serves over 100 law firms and corporate legal teams, including Magic Circle firms, White Shoe firms, and multinational corporations such as BT Group and Deloitte. The U.S. market accounts for 30% of the company’s revenue. Since its 2020 launch, Definely has grown to 84 employees and expects to surpass 100 by late 2025.
Why the $30 Million Series B Matters
This funding brings Definely’s total capital raised to $40 million, a significant jump from its $7 million Series A in May 2024. The new investment will support:
- Faster AI product development, including improvements to Enhance.
- Expansion into the U.S., with local leadership hires and relocating key staff to the East Coast.
- Capital-efficient growth, with CEO Emelifeonwu highlighting a measured and disciplined approach.
Morgan Kessous, Partner at Revaia, praised Definely as a leader in vertical AI for legal workflows. This Series B is also Revaia’s first UK investment, marking an important step in their European strategy.
A Vision Rooted in Accessibility and Efficiency
For Emelifeonwu, the funding is more than capital—it represents breaking barriers. “From a two-bedroom council flat to $30 million Series B,” he reflected, pointing to challenges faced by underrepresented founders in Europe. The raise confirms Definely’s mission: to build AI tools that address real workflow problems with a human-first approach, rather than chasing buzzwords.
Reimagining Legal Workflows with Agentic AI
The co-founders describe Enhance as part of a shift toward “agentic AI” — software agents that manage specialized tasks together, allowing legal professionals to focus on oversight and decision-making. Feargus likens it to Ford’s assembly line: “Agentic AI will be our workforce,” handling research, proofreading, drafting, and review, while lawyers ensure quality and final judgment.
What Comes Next
Alongside the new funding, Definely is expanding its U.S. presence, appointing a General Manager and planning physical offices in both the U.K. and East Coast. The company has a clear roadmap to enhance its agentic AI system with future product releases aimed at boosting efficiency and accuracy for legal teams.
Conclusion: Transformation Through Focused Innovation
Definely’s evolution started with a simple accessibility challenge and now delivers practical AI solutions for legal professionals. With fresh funding and a focused growth plan, it is set to redefine legal productivity globally. In an industry often slow to adopt new technologies, Definely proves that AI built around genuine user needs can drive meaningful change.
