The company behind Ronja.

Before starting Ronja, Anton Melander and Adam Lewenhaupt worked at Northvolt, building data infrastructure for a complex industrial operation. They saw a pattern that extended beyond one company: established businesses already had capable core systems, but the work that made each operation specific still depended on people connecting data, applying rules, and carrying context between them.

That same fragmentation also limits how much value a company gets from the data it already has. Ronja brings data and business logic together so teams can answer important questions, build analytics, and run recurring reports from consistent definitions–instead of gathering and reconciling the same information by hand.

Ronja was founded in Stockholm in 2024 to close that gap. The aim is practical: keep the systems a company already trusts, use their data for dependable answers and reporting, then give domain experts a way to build the company-specific applications, agents, and automations those systems leave behind.
