Our domains: energy, real estate, space and the systems that connect them. We focus on the operating systems behind physical assets - AI-driven interfaces, robotics, hardware-software systems for resilience, and the infrastructure needed to power an increasingly compute-intensive world. Founders ourselves - we’ve built, scaled and exited companies (and know how hard it is). Practical support. Long-term orientation. Fast process, no nonsense.
