Overview

Polar is a developer-focused payment and billing infrastructure company operating at polar.sh. It combines usage metering, subscriptions, invoicing, checkout, and merchant-of-record services for software businesses, with particular relevance to AI products whose costs and prices vary by tokens, API calls, or other usage events.

The company is positioned as an alternative to assembling separate billing, tax-compliance, payment, and customer-portal systems. Its open-source and developer-oriented approach, event-based billing model, and support for global digital-product sales distinguish it from conventional subscription billing providers.

History

Polar was founded in 2022 by Birk Jernström, who previously co-founded Tictail and later worked on Shopify’s Shop product. The company developed Polar as developer-focused billing and merchant-of-record infrastructure for software businesses. Its focus has expanded toward usage-based billing for AI products, including metering events such as tokens, API calls, and compute usage. No acquisition or parent-company relationship was identified.
