Tibber bets EU dynamic-tariff rules make real-time power the default; 1M users by 2023

App-first electricity retailer that buys power at market price, sells it to households at cost-plus-subscription, and shifts EV, heating and battery use to cheap hours.

That selling electricity at real-time spot price, steered by an app, becomes the default — and EU rules entitling consumers to dynamic contracts would mainstream it.

$12M Series A (2019, Founders Fund) and $65M Series B (Nov 2020, Eight Roads/Balderton)

Founded in Oslo in 2016 by Edgeir Vårdal Aksnes and Daniel Lindén, who saw traditional utilities as opaque; launched app-first retail electricity at real-time prices with smart-home control, and took a $12M Series A from Founders Fund in 2019.

Expanded to Sweden, Germany and the Netherlands; raised a $65M Series B in Nov 2020 with 100,000 paying households; hit 1M users in Oct 2023 with ~SEK 8.3B 2022 revenue; EU electricity market design reform entered into force 16 July 2024, entitling consumers to fixed or dynamic price contracts and cementing the model; added the Homevolt battery, Grid Rewards and a residential VPP.

Still running and scaling: by Aug 2025 claimed Europe's largest residential VPP (137,000 MWh shifted in a year) and kept expanding across four markets.

A digital retailer could only sell spot-priced power where regulation allowed it, so the law was part of the product from day one.

The EU's 2024 market-design reform made dynamic price contracts a consumer entitlement, validating the model faster than any marketing campaign.

Passing 1M users across four countries before the reform shows the bet worked even where dynamic tariffs were optional.

Aggregating customer devices into a VPP extends the same bet: flexibility markets, like tariffs, are being pried open by regulators.

When a regulation turns a niche model into a consumer right, the operator already running that model at scale captures the opening — regulators become part of the go-to-market plan.

As of September 2026 Tibber continues to operate in Norway, Sweden, Germany and the Netherlands with more than a million users. It expanded from tariffs into hardware and grid services — the Homevolt battery and Grid Rewards — and in 2025 claimed Europe's largest residential VPP, having shifted 137,000 MWh in a year. Its growth rests on the regulatory shift it bet on: dynamic tariffs are now a consumer right under EU law rather than an anomaly.
