Documented cause
Spiir, a Danish personal finance management app founded by Mathias Kiersgaard that used bank screen scraping and later PSD2 APIs, was acquired by Lunar in 2021 and immediately discontinued as a standalone product. Despite having over 350,000 Danish users and raising approximately DKK 30M, the company was unable to monetize its free user base through premium subscriptions or open banking data services. Lunar acquired Spiir primarily for its data aggregation technology and user acquisition funnel, retiring the Spiir brand entirely within months of acquisition.
Lesson
“Free PFM apps with no monetization path are technology acquisitions waiting to happen, not businesses.”
