Credyt
Hey HN! I'm the founder of Credyt (https://credyt.ai). If you're running an AI product that burns $0.50+ per interaction, you need to bill customers as usage happens, not at the end of the month. Otherwise you're a bank for your customers, and you'll run out of money before they do. Why invoice-based billing doesn't work for AI: Most usage-based billing tools (Stripe Billing, Orb, etc.) were built for SaaS. They meter usage all month, then send an invoice. That works fine when your COGS is 5%. It's a disaster when you're paying your AI vendor upfront for every request and your…

What it does
Credyt is a wallet-native monetization engine built for AI. Define pricing in any currency and charge for usage as it happens from pre-funded credit accounts. Give your customers an Open-AI like billing experience in days not months: top-ups, auto recharge, usage reporting and more.
Credyt is real-time monetization infrastructure for AI. Observe your spend, control your exposure, and bill your customers across every pricing model.
Real-time monetization for AI. Observe your spend, control your exposure, bill your customers across every pricing model you use today or might use tomorrow. The Credyt team comes from Visa, Checkout.com, TrueLayer, and SumUp. We've built monetization infrastructure at scale and know exactly where it breaks. We built Credyt so you don't have to find out yourself. You built something people use. But you don’t know whether to charge per token, per request, per seat, or per output. So you’re either not charging at all, or you slapped on a flat fee that has nothing to do with usage. Either way, money is being left on the table or burned. Unlike traditional SaaS, every API call costs you real…from credyt.ai

Autumn2025 · useautumn.com · ▲719If you’re on tech twitter you may have noticed an increasing dissent with Stripe and it’s DX. t3.gg (Theo) summarizes it best: “IMO, the biggest issue with Stripe is the "split brain" it inherently introduces to your code base. When a customer checks out, the "state of the purchase" is in Stripe. You're then expected to track the purchase in your own database via webhooks. There are over 258 event types. It's far too easy to have a payment be failed in stripe and "subscribed" in your app.” We've built an OSS abstraction to build any pricing model 1 line of code. The idea is a layer over…
Invoce.aiJan 2026 · invoce.ai · ▲158Hey HN, I’m Atmiya. I built Invoce.ai because invoicing always felt unnecessarily slow and bloated. Most tools make you click through forms and settings just to send an invoice. With Invoce, you simply chat with AI, describe the work you did, and it creates a clean invoice instantly. It’s early and intentionally simple. I’m curious how others here handle invoicing today and what feels most frustrating. Happy to answer questions and hear feedback.
I made a credit system API2024 · creduse.com · ▲42I'm a solopreneur and I made it very easy to integrate a credit system into your apps and games using Creduse. I built Creduse because more and more users want pay-as-you-go models, and founders need new ways to increase user engagement or nicely limit cost-intensive features (see AI). Creduse is built by a developer for developers. I hope it will help as many startups as possible. Feedback are very much appreciated. Francesco
