Echo

Hey Product Hunt! Sam here, founder at Merit Systems. We’re in a platform shift thanks to GenAI. The shape of apps and teams of the future will look different. We want to enable the long-tail of devs to ship and monetize with the lowest R&D cost possible. I saw how the innovation sausage gets made during my time at a16z, Echo is our take on enabling the next wave. Most builders (us included) get 90% to launch on an AI app, then stall on the last rancid 10%: Stripe, auth, metering, billing, taxes, receipts, entity setup. Echo handles the business layer out-of-the-box so you can ship and charge per use. What that looks like: – ~5-line change from Vercel AI SDK to monetization – Auth → route & meter AI calls → per-call payments → receipts/taxes handled – We’re the merchant of record, so you don’t need to spin up an LLC just to test an idea Early use cases we’re seeing: image-gen apps using nano-bannana (new Google Gemini model) and gpt-image-1; “Shirtslop” (prompt → shirt) is a fun one. The models are so good your app can be thin, monetized with Echo, and users see immense value. This is our second product. We’re a 7-person team in Williamsburg, NYC, and Echo sits on top of our global payout + tax compliance infrastructure. It's less fun than AI apps but necessary for where we're headed. We worked hard to own the rails so we can be cheap and global by default. We’re giving developers $10k in credits to get building, comment and I’ll get you set up.
