Definely's $30M Boost: Transforming Legal AI

The legal profession, long considered a bastion of tradition and paperwork, is undergoing a quiet revolution—one powered by artificial intelligence. At the heart of this transformation is Definely, a UK-based legaltech startup that’s rapidly carving out a reputation for innovation. On June 9, 2025, Definely announced a $30 million Series B funding round—led by Revaia and supported by Alumni Ventures, Beacon Capital, and Clio Ventures—bringing its total funding to $40 million[1][2][3]. The company’s mission? To supercharge legal workflows with advanced AI, making lawyers’ lives easier and their work more efficient. As someone who’s followed the legaltech space for years, I can say this is more than just another funding story—it’s a sign of how quickly AI is reshaping even the most time-honored professions.

Why This Matters: The Legal AI Boom

Legal AI is no longer a novelty—it’s a necessity. Law firms and corporate legal departments are under pressure to deliver results faster, reduce costs, and minimize errors. Enter Definely, whose generative AI-powered tools are designed to tackle the pain points lawyers face every day. Nnamdi Emelifeonwu, Definely’s co-founder and CEO, put it best: “We’re 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.”[2] This commitment to real-world solutions, rather than flashy tech for tech’s sake, is a big reason why Definely’s products are gaining traction—especially in the US, where 30% of the company’s revenue now comes from[2].

The Definely Story: From Startup to Legaltech Leader

Definely was founded with a clear vision: to automate and enhance the tedious, error-prone aspects of legal document review and contract management. The company’s latest product, ‘Enhance,’ is its first agentic AI offering—meaning it can perform tasks autonomously, such as suggesting edits, flagging inconsistencies, and even drafting clauses. The launch of Enhance has been met with enthusiasm from customers, who appreciate its ability to streamline workflows and reduce the risk of oversights[2][3].

Definely’s growth has been fueled by a series of strategic investments. Its Series B round included participation from both new and existing backers, such as Octopus Ventures, Zrosk Investment Management, The Raine Group, and Cornerstone VC[2]. Morgan Kessous, Partner at Revaia, highlighted the company’s potential: “We are proud to lead Definely’s Series B and support a company that is setting the standard for AI-powered legal technology.”[2]

The Technology Behind Definely

Definely’s platform combines generative AI, natural language processing (NLP), and machine learning to transform legal documents. Its tools can review contracts, suggest improvements, and even automate repetitive tasks. This isn’t just about saving time—it’s about reducing human error and improving the quality of legal work.

One of the standout features is the platform’s ability to understand context. For example, when reviewing a contract, Definely’s AI can identify ambiguous language, missing clauses, or potential risks, and suggest specific improvements. This kind of nuanced understanding is rare in legaltech—most tools focus on surface-level checks, but Definely goes deeper.

Real-World Impact and Use Cases

Definely’s technology is already making a difference in the real world. Law firms and corporate legal teams use the platform to review and redline contracts, manage due diligence, and ensure compliance. The US market, in particular, has embraced Definely’s tools—perhaps unsurprising given the country’s litigious culture and the sheer volume of legal documents generated every day.

The company’s success in the US is a testament to the universal appeal of its products. As of June 2025, Definely’s US operations account for nearly a third of its revenue—a figure that’s likely to grow as the company invests more in global expansion[2].

The Broader Legal AI Landscape

Definely isn’t the only player in the legal AI space, but it’s certainly one of the most ambitious. Other companies, such as Kira Systems, Luminance, and eBrevia, offer similar tools for contract review and due diligence. However, Definely stands out for its focus on agentic AI—systems that can act autonomously, rather than simply offering suggestions.

The People Behind the Tech

Definely’s leadership team is a mix of legal and tech expertise. Nnamdi Emelifeonwu, the CEO, is a former lawyer who understands the challenges of legal work firsthand. This blend of domain expertise and technical acumen is crucial—after all, building AI for lawyers requires more than just coding skills; it demands an understanding of how legal professionals think and work[2].

The company’s investors also bring valuable experience. Clio Ventures, for example, is the investment arm of Clio, a leading legal practice management software company. This partnership gives Definely access to a vast network of legal professionals and potential customers[4].

What’s Next: The Future of Legal AI

With $30 million in fresh funding, Definely is poised to accelerate its global expansion and product development. The company plans to roll out new features and further integrate its agentic AI capabilities into legal workflows. According to Emelifeonwu, there are “a series of further exciting features in the pipeline”[2].

Looking ahead, the legal profession is likely to see even more AI-driven innovation. As AI models become more sophisticated, they’ll be able to handle increasingly complex legal tasks—perhaps even advising on strategy or predicting case outcomes. For now, though, the focus remains on automating routine work and reducing the risk of human error.

Challenges and Considerations

Of course, the rise of legal AI isn’t without its challenges. Lawyers are understandably cautious about relying on machines for critical decisions, and questions about ethics, accountability, and data security remain. Definely, like other legaltech companies, must address these concerns head-on if it wants to win the trust of the legal community.

There’s also the issue of talent. As Vered Dassa Levy, Global VP of HR at Autobrains, notes, “Finding [AI experts] is very challenging, especially given the high demand that exceeds the existing supply.”[5] Definely’s ability to attract and retain top AI talent will be key to its long-term success.

Why You Should Care

If you’re a lawyer, legal professional, or just someone interested in the future of work, Definely’s story is worth watching. The company’s success is a reminder that AI isn’t just for tech giants—it’s for everyone, including those in the world’s oldest professions.

Conclusion: The Legal Revolution is Here

Definely’s $30 million Series B funding round is more than just a financial milestone—it’s a signal that the legal profession is ready for change. With its agentic AI approach, global ambitions, and deep understanding of legal workflows, Definely is leading the charge toward a smarter, more efficient future for lawyers everywhere.
