The joy of building

Apps that make
everyday life
simpler

Firestarter AS is a family-run app studio that builds products people actually use — crafted with passion, self-built technology and a careful eye for what truly matters.

What we build

Two apps.
Thousands of users.

We develop focused mobile apps that solve concrete everyday problems — backed by custom-built API infrastructure, high-quality data and thoughtful design.

Spotprisen

spotprisen.no ↗

Spotprisen delivers a clear, hour-by-hour view of electricity spot prices across Europe and the UK. We pull data from multiple sources and process it through a self-built, high-performance API — so you always see the latest prices without delays or middlemen. No ads. Just the data you need.

  • Over 12,000 data points ingested and processed every single day
  • Self-built backend API for maximum speed, reliability and control
  • Full coverage across Norwegian, Swedish, Danish, Finnish and European price zones
  • Used daily by thousands of households and businesses across Europe

Utreise
utreise.no ↗

Utreise was born from a real problem Lars experienced himself as an offshore worker: keeping track of helicopter departures to and from the Norwegian continental shelf was fragmented and unreliable. The app centralises all flight information in one place — departures, delays, push notifications and full route timelines — drawn directly from Avinor's official API.

  • Real-time overview of all helicopter departures to the Norwegian shelf
  • Push notifications for delays and route changes — even when the app is closed
  • Full flight timeline from planned departure through to actual landing
  • Light and dark theme with automatic adaptation to system settings

Who we are

Small studio.
Strong technology.

Firestarter AS is a family-run app development studio based in Langesund, Telemark. We are three: a developer, an accountant, and a designer — working closely together to deliver products that genuinely work in people's everyday lives.

We believe that great software starts with a real need. Both of our apps exist because we experienced the gap in the market ourselves. That means we understand our users — because we are them.

We build our own API infrastructure from scratch to guarantee speed, reliability and full control over the data we deliver. No third-party bottlenecks. No compromises on uptime.

Firestarter AS operates as part of the Prodigy Holding AS group, running as an independent product company with its own direction and identity.
