NRGY One Raises Seed Funding Backed by GLB Gruppe
NRGY One Secures Seed Funding
NRGY One AG, a Swiss energy startup based in the canton of Bern, has raised a Seed round. The round is backed by GLB Gruppe, a construction group that participates both as investor and strategic partner in the company.
What NRGY One Does
Founded in 2022, NRGY One (formerly Siima Solution) is building what it describes as a "Neo Energy Supplier" positioned ahead of the liberalisation of the Swiss electricity market.
The company's core product is Stromkonto, a platform that operates as a virtual battery. Under the model, solar owners have every kilowatt-hour they produce credited to a virtual account that they can draw on year-round.
The Stromkonto system is delivered through three components:
- A mobile app for account access and management
- The whatwatt Go device, which attaches to the existing smart meter
- A subscription billing model
Stromkonto has been live across Switzerland since July 2025.
Strategic Direction
With GLB Gruppe on board as both investor and strategic partner, NRGY One is working to evolve Stromkonto from a virtual battery product into a digital energy-trading platform for prosumers. The company frames this evolution around the broader liberalisation of the Swiss electricity market, positioning itself as a new type of energy supplier for solar owners who both produce and consume electricity.

Why It Matters
The Swiss electricity market has historically been closed to the kind of prosumer trading models that NRGY One is building toward. The company's bet is that liberalisation will open a market for digital platforms that let solar owners monetise and manage their production more flexibly than traditional net metering allows.
Stromkonto's virtual battery concept addresses a common pain point for solar owners: production is seasonal and weather-dependent, while consumption is continuous. By crediting every kilowatt-hour to a virtual account that can be drawn down year-round, NRGY One offers a form of storage without physical batteries.
The involvement of GLB Gruppe as a strategic partner is notable given the construction group's likely exposure to building-integrated solar and residential energy installations. For NRGY One, that relationship could provide distribution reach into new solar installations as well as credibility with property owners and developers.
