Lua, billed as an operating system for human-agent collaboration in the workspace, has secured £4.3m in funding led by Norrsken22.

Additional investors include Flourish Ventures, 20VC, P1 Ventures, Phosphor Capital and Y Combinator along with notable angels Henri Stern (CEO Privy), Kaz Nejatian (CEO of Opendoor) and Med Benmansour (CEO of Nuitee).

Lua enables any team, regardless of technical depth, to build, own, and manage their own agent workforce from day one. The company is founded by Lorcan O’Cathain and Stefan Kruger, who met while scaling a FinTech business in East Africa – Lorcan as COO, Stefan as CTO.

Before Lua, Lorcan was MD of Zephyr Management’s Africa business, a leading VC/PE fund operating across Africa, India and Sri Lanka. Stefan was VP of Engineering at Paystack, joining before the Stripe acquisition.

Lua will use the funding to continue to build out its developer community and the Lua Implementation Network, a growing community of independent partners deploying Lua agent workforces in their own markets around the world.

Since launching its agent developer platform in October 2025, Lua has grown revenue close to 30% week-on-week. In February 2026 alone, more agents were built on Lua than in the entire cumulative period since launch.
