We build charging and battery storage solutions that electrify commercial sites and their truck fleets, and we provide the full solution: planning, financing, construction and operations. Our team has already delivered some of the largest battery projects in Europe. Today we have over 150 MWh of storage capacity in development and plan to invest more than €300M by 2030. Our mission: make emission-free road freight possible and strengthen Europe's energy independence along the way. Why now is a good time to join We were founded last year, closed our pre-seed round, and are growing steadily from around 15 people today to 20–25 over the next six to nine months. We have signed contracts, revenue in the millions this year, and a healthy pipeline behind it.Real traction, not hype. Our customers range from the oldest brewery in the world to multi-billion-euro logistics players and a lot of German Mittelstand.An unfair advantage on cost. Battery purchasing scale through our sister company lets us price in a way most startups in this space simply can't, and we have serious infrastructure project finance know-how in-house.A market that just tipped. Depot charging has gone from "will this work?" to "when do we start?" for truck electrification, and road transport is still one of the biggest untapped decarbonization levers in Europe at roughly 8% of EU emissions.A huge, early impact.
