Hi HN,

I’m Vijay (founder @ RevMax AI) — we’re building a “Revenue OS” for AI agent startups. I’ve spent the past year working on flexible billing infrastructure and want to battle-test our new SDK in the real world.

What I’m offering (totally free, no catch):

I’ll build a complete billing flow for your product in the next 24 hours:

Event metering → pricing logic → Stripe (or your gateway) invoicing

Basic cost + margin dashboard

Sample tests + clean README for easy handoff

Node/TypeScript or Python (your call), PostgreSQL, Stripe Connect by default

All code is yours — open-sourced under MIT if helpful to others.

Why I’m doing this:

Real-world > sandbox tests

Want to prove how fast + flexible billing should be

If it works for you, awesome. If not, I learn.

How to get picked:

One pricing/billing edge case you're stuck on

I’ll post progress + a retro tomorrow.
