To a developer, it can begin with a POST /subscriptions request.
To the household behind that request, something much larger starts moving. An old electricity contract may need to be cancelled. A new supplier has to be registered with the grid operator. Metering needs to work. Bills need to arrive. The new contract eventually has to begin delivering power.
Nomos is trying to hide that machinery behind software.
The Berlin company has raised €20 million in funding led by Index Ventures, joined by Bolt founder Markus Villig, UiPath founder Daniel Dines and Nord Security co-founder Tomas Okmanas. Founded by Stefan Gerbes and Nils Bitzer, Nomos is building a regulated electricity business that hardware manufacturers and energy installers can place behind their own brands.
The unusual part is what sits underneath the API.
Nomos is itself a licensed electricity supplier and balancing responsible party in Germany. Its infrastructure covers plans, subscriptions, procurement, metering and billing, while partners decide what the customer-facing experience looks like. They can use Nomos-hosted checkout pages or build the entire interface themselves against its API and webhooks.
That abstraction becomes more interesting once electricity stops behaving like a simple monthly commodity.
On a Nomos dynamic plan, the variable electricity price can follow the EPEX day-ahead market in 15-minute intervals. A home-energy system can pull those prices, identify cheaper periods and schedule flexible equipment such as an EV charger, heat pump or battery around them. Afterward, consumption data can be matched against those same intervals to calculate what actually happened.
Even the physical smart meter can become part of the software workflow. Nomos says partners can order German iMSys smart meters through its platform, track installation milestones and target roughly an eight-week installation window through its metering partnerships. Once activated, the meter can unlock dynamic billing, §14a grid-fee reductions and 15-minute energy data.
Solar changes the direction of the transaction again. The same subscription model can support feed-in, where electricity moves from the household into the grid and money moves back to the customer. Nomos handles the grid registration and calculates credits using EPEX day-ahead prices.
This helps explain why the €20 million matters.
The company is not merely building another electricity app. It is trying to make the complicated work behind electricity retail programmable enough that a solar installer, battery manufacturer or home-energy company can become the brand the customer associates with power without rebuilding a utility underneath it.
Nomos has even packaged its API knowledge into a reusable skill for coding and operations agents, allowing AI systems to understand its endpoints, permissions and versioning. But the difficult part is not making electricity look like software.
It is making the regulation, grid communication, meters, invoices and market settlement behind that software remain reliable when millions of homes depend on it.
That is the real bet behind Nomos.
The company is not trying to remove the complexity of the electricity system. It is trying to make everyone building on top of it stop having to see it.
