NRGY One AG (formerly Siima Solution) is a Swiss energy startup founded in 2022 and based in the canton of Bern. Its Stromkonto platform, live across Switzerland since July 2025, works as a virtual battery: solar owners have every kilowatt-hour produced credited to a virtual account they can draw on year-round, using a mobile app, a whatwatt Go device attached to the existing smart meter, and a subscription billing model. Backed by construction group GLB Gruppe as investor and strategic partner, the company is positioning itself as a "Neo Energy Supplier" ahead of the liberalisation of the Swiss electricity market, evolving Stromkonto into a digital energy-trading platform for prosumers.
