Robin AI's legal-AI bet ends: failed $50M round, Scissero split, Microsoft hires team

A London legal-tech company that fine-tuned Anthropic's Claude on legal text to draft, review and negotiate contracts, selling software (a Microsoft Word copilot) plus human-in-the-loop managed legal services.

That lawyers would pay for a Claude-powered contract copilot plus managed services, and that fast global scaling could outrun rivals before capital turned scarce.

Over $13M by Feb 2023 (seed in 2021, then a £8.8M Series A), a $26M Series B in Jan 2024 led by Temasek, and $25M more raised outside a traditional round in 2024 — roughly $64M by end-2024.

Richard Robinson, a former Clifford Chance and Boies Schiller Flexner lawyer, and machine-learning researcher James Clough founded Robin AI in London in 2019, betting generative AI could automate contract work. In February 2023 Robin became the first commercial startup to integrate Anthropic's Claude models, fine-tuning them on legal text for drafting and negotiation and selling a 'lawyer-in-the-loop' product. TechCrunch reported it had raised over $13M from investors including Plural, Episode 1 and the Google Black Founders Fund.

In January 2024 Singapore's Temasek led a $26M Series B to fund a US expansion and Asia-Pacific launch; clients already included PepsiCo, and the contract copilot had shipped as a Microsoft Word add-in. In January 2025 Robin ranked 10th on The Sunday Times 100 Tech list, reporting 227.39% sales growth over three years, £7.7M of sales in 2024 and US operations that grew six-fold. But CTO James Clough left for Encord early that year. By October 2025 a planned $50M round had failed to close, the company had made widespread layoffs, and it was listed on an insolvency marketplace — its own listing claimed $10M ARR and a $16M pipeline, while a source told Legal IT Insider the company was on track to lose about £11M that year.

In December 2025 Scissero, an AI-enabled UK law firm, acquired Robin AI's managed-services business. In January 2026 Microsoft hired a raft of Robin AI engineers and product specialists into its Word team; Microsoft said it had no plans to acquire the company or its remaining technology, ending Robin AI as a standalone startup.

Robin AI blended an AI copilot with human managed services, which produced revenue but also a people-heavy cost base that needed constant venture fuel.

The January 2025 Sunday Times ranking and 227% growth created an expectation of 'AI-level' growth that a ~$10M-ARR legal business could not meet when the next round came due.

Scaling offices across London, New York and Singapore plus a six-fold US build-out left little room for error when the $50M round failed to close in October 2025.

The assets split cleanly in distress: Scissero wanted the services clients, Microsoft wanted the Word-integrated AI engineers — nobody wanted the standalone company at its last valuation.

Being first to pair a frontier model with a familiar workflow and brand-name customers did not protect Robin AI: when the next round failed, legal-tech-scale growth was not enough to stop the breakup.

As of 2026-01-15 Robin AI is gone as a standalone company. Its managed-services business and clients went to AI-enabled UK law firm Scissero in December 2025; in January 2026 Microsoft hired multiple former engineers and product specialists into its Word team, saying it had no plans to acquire Robin AI itself. CEO Richard Robinson's next move was unannounced. The startup had raised roughly $64M through 2024, ranked 10th on the Sunday Times 100 Tech list in January 2025, and was listed for distressed sale that October after a $50M round failed.
