What they do

Problem

AI startups struggle to implement and evolve flexible billing models like usage-based pricing, credits, and subscriptions without complex code and webhook-heavy Stripe integrations.

Solution

Autumn provides open-source billing infrastructure on top of Stripe that tracks entitlements and usage and lets teams implement pricing plans via a simple API with built-in versioning and migrations.

Who it's for

AI startups and developer teams (including YC companies) building SaaS products with complex, changing pricing and usage-based billing.
