"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."
— Ulrik Stig Hansen, Co-Founder and Co-CEO

The Series A round was led by Blackbird Ventures and will support international expansion and product development.
