About Autumn
Autumn is open-source infrastructure over Stripe that allows AI startups to build their pricing plans quickly, and flexibly. We act as your app's DB and manage who's paying for what, track usage and manage customer feature access.
YC companies use us because we make it easy to handle common pricing models like usage-based, credits, subscriptions, rollovers and more in 3 functions and no webhooks.
As you scale, you get reliable billing, that you can change however you want without wrangling code (we handle versioning, migrations etc), and manage custom pricing too. Everything you could down the line (credits, multiple subscription groups, rollovers, referral program, usage analytics, centralized team billing etc), you can drop in at any point.
What Autumn does
Autumn is billing infrastructure for AI startups. It handles usage limits, credits, and subscription logic so you do not have to rebuild them. The system keeps payments, webhooks, and usage in sync while working on top of Stripe. It is for companies that want to iterate on pricing and sell custom contracts faster. Pricing starts free for up to 8K monthly billing volume, with paid tiers for scaling teams and custom enterprise needs. Stripe fees still apply.
