In this episode, we speak with Nnamdi Emelifeonwu, a former Freshfields associate and now co-founder of Definely - one of the UK’s most exciting legal tech companies.

Nnamdi traces his journey building a legal career at a Magic Circle firm and ultimately leaving it all behind to solve a problem he first encountered while working alongside his visually impaired colleague Feargus MacDaeid who would become his co-founder.

Nnamdi shares the story of how he and Feargus turned an initial prototype into a Microsoft Word plug-in - and eventually a fast-growing platform now used by over 100 corporate customers like BT and JPMorgan, and law firm giants including A&O Shearman, Cravath and Milbank.

He discusses the steep learning curve of becoming a founder without a technical background, the early product iterations and how the startup found its first champions at firms like A&O and clients like Deloitte.

He also opens up about the realities of startup life: fundraising, cash flow pressure, making hiring mistakes, and learning to let go of perfectionism - particularly as a lawyer-turned-founder.

With Definely now backed by $7 million in Series A funding from Octopus Ventures and expanding into the US, Nnamdi reflects on the changing role of lawyers in the age of AI and why the future of the profession depends on embracing legal tech.

He also offers candid advice for lawyers considering a move into entrepreneurship, including the importance of resilience, self-belief and maintaining a growth mindset.
