Autumn

Why we moved Autumn to a multi-region architecture, the tradeoffs we hit with active-active Redis, and why we eventually returned to a simpler single-region setup.

Thoughts on billing infrastructure, usage-based pricing, and building for AI startups.

How we automated customer support investigations by structuring our logs and giving Claude Code the right primitives.

Some patterns we've found ourselves adopting as we design Autumn's API increasingly for agents instead of humans.

Building billing in-house starts simple, but real-time checks, credit ledgers, reset rules, rollovers, custom contracts, analytics, and pricing changes become hard to maintain over time.

Metronome is built for sophisticated usage metering and rating. Autumn is built for AI and SaaS companies that need credits, entitlements, enterprise contracts, committed spend, and Stripe billing state in one application-facing system.

Orb is built for usage events, complex pricing queries, ledgers, simulations, and invoicing workflows. Autumn is built to manage application billing state like credits, limits, entitlements, rollovers, reset intervals, and custom packages.

Stripe Billing is the subscription, invoice, and payment layer. Autumn runs on Stripe and adds product-facing billing state for credits, entitlements, access checks, and pricing iteration.
