Luminance, the UK-based legal AI startup, has secured $75 million in a Series C funding round, marking one of the largest funding rounds for a pure-play legal AI company in the UK and European markets. Led by Point72 Private Investments, this latest round brings Luminance’s total funding in the past year to $115 million, and its overall total to $165 million. Other investors, including Forestay Capital, RPS Ventures, and Schroders Capital, also participated, alongside existing backers such as March Capital and Slaughter and May.
A Legacy Of Innovation
Luminance’s roots trace back to Cambridge, where it was founded by Adam Guthrie and Dr. Graham Sills, with seed funding from the late Dr. Mike Lynch, the renowned founder of Autonomy. Tragically, Lynch passed away in an accident last year, leaving behind a legacy of groundbreaking work in AI.

Legal-Grade AI For Contract Management
Luminance’s AI, designed specifically for the legal field, aims to automate and enhance every stage of contract management—from generation and negotiation to post-execution analysis. Its proprietary platform, Lumi Go, allows clients to send draft agreements to counterparts and have the AI auto-negotiate on their behalf.
What sets Luminance apart is its unique Legal Pre-trained Transformer (LPT), trained on over 150 million verified legal documents—many of them non-public—making it more defensible than AI models built on general-purpose, open-source data. The company believes this approach offers greater accuracy and reliability, particularly in legal settings where trust is paramount.
Expanding Global Footprint
With over 700 clients across 70 countries, including major players like AMD, Hitachi, Rolls-Royce, and Lamborghini, Luminance has rapidly expanded its presence. The company recently opened new offices in San Francisco, Dallas, and Toronto, alongside an expanded US headquarters in New York. Its headcount has reportedly tripled in North America, underscoring the growing demand for specialized legal AI solutions.
AI For Lawyers, By Lawyers
Eleanor Lightbody, CEO of Luminance, emphasizes that the platform is designed with lawyers in mind. “Our specialized AI ensures that outputs are validated and trusted, making it ideal for the legal domain,” she explained. The platform’s mixed-model approach, where different AI models verify each other’s results, is a key differentiator, providing clients with the most accurate and transparent answers.
Revolutionizing Contracting
Sri Chandrasekar, Managing Partner at Point72 Private Investments, highlighted the immense potential of next-generation AI in revolutionizing contracting processes. Luminance’s continued growth reflects a strong belief in the transformative power of AI within the legal sector, positioning the company as a leader in the rapidly evolving legal tech space.
Luminance’s ambitious journey continues in the wake of its visionary founder’s passing, promising to reshape the way contracts are managed and negotiated with the help of cutting-edge AI.
