Meet Polar
The billing stack for the intelligence era
Tokens in,
revenue out
Primitives
New financial primitives
that compose however you price
Usage billing, subscriptions and credits as building blocks. Combine them on a single product and change your pricing without rebuilding billing.

Summarise the churn interviews from this quarter
Three themes came up most. Onboarding took too long, usage limits were unclear, and finance wanted invoices they could forecast.

“The Polar team treated us like a design partner, not just a customer. They built features we needed on tight timelines and worked collaboratively to resolve issues. That’s rare.”

Your customer consumes usage.
Polar bills, collects and complies.
You get paid.
Unit economics
The only billing stack
that knows your margins
Polar already collects every payment, so placing inference cost beside it reveals your true gross margin per customer. The $90 plan burning $600 of tokens stops hiding in your averages.
