Ruslan Kosarenko

Lawyer and Entrepreneur

Managing Partner of Sterling Law (Legal 500)

Director, Humanoid.ai UK (to July 2026); Director, Humanoid US and Canada (present) — a UK-based humanoid robotics unicorn, valued at $1.35bn post-money following a $152m Series A in July 2026 led by Prime Movers Lab, with Bosch, Schaeffler, Fubon Financial Holding Venture Capital and Aglaé Ventures participating ($270m raised to date).

Founder, CaseCraft.AI — an AI-driven “access to justice” platform automating small claims, founded together with Michael Iatsukha, Dmitry Bagrov (managing director of DataArt, who established its UK office) and fund manager Alexander Mints, with Ed Crosse — Simmons & Simmons partner and former president of the London Solicitors Litigation Association — as adviser. The platform uses chatbots to guide claimants and defendants, with a team of legal reviewers and solicitors checking the AI’s output, and charges a success fee rather than upfront costs. Since launching at the start of 2026 it has attracted over 3,800 sign-ups representing claims worth close to £11m, with plans to extend into personal injury and employment claims and, in time, to raise the claim ceiling substantially and expand into Scotland, Canada, Australia and New Zealand.

Notable Cases

Sponsor licence delays escalated to central government

Ruslan successfully escalated sponsor licence delays to central government. He acted for a UK advanced-technology manufacturer in the robotics sector facing damaging Home Office delays in processing its sponsorship arrangements, and escalated the matter to the relevant sponsoring government department to press for intervention, pursuing escalation routes beyond the standard channels to protect the client’s hiring plans.
