Y Combinator is a startup accelerator that has supported numerous prominent technology companies.
The oversubscribed funding round was led by Portage Ventures with participation from F Capital and existing investors.
"Happl began with a simple belief: benefits should be easy to understand, easy to manage and easy to implement. What we’ve built goes far beyond that, a global platform that removes complexity at scale and connects employees with solutions that truly reflect their needs."
Wellington Management led the financing round, which brings total funding to £110m.
"Everyone is focused on building bigger models, but for physical AI, the bottleneck isn't model size. It's data readiness. You can have the most sophisticated model in the world, and it will still fail if the data feeding it is incomplete, inconsistent, or misaligned with real-world conditions. That's the problem we solve."
The Series A round was led by Blackbird Ventures and will support international expansion and product development.
"Trades businesses are overwhelmed by calls, emails, and admin – and that friction directly costs them revenue. We’re building AI agents that work like effective front-office staff: answering every call, booking every job, and integrating deeply into the systems trades already use."
The Series B round was co-led by Visionaries and 20VC with participation from Thomson Reuters, Y Combinator, and numerous angel investors.
"We recognised a clear market need for AI systems that truly understand the structure and logic of patents and can support professionals across every step of the process. By combining frontier research backgrounds with patent law experience, they set out to build an AI platform purpose-built for the realities of patent drafting, prosecution and analysis."
The Series A round was led by FT Partners to expand international operations and grow the engineering team.
