Logic, Inc.▲296Hey HN, I’m Steve, founder of Logic, Inc (https://logic.inc). Over 16 years on HN, this is my third startup launch! Logic came from years I spent at Brex and Convoy building internal automations for our Ops teams. Every team had detailed SOPs, but automating pieces of them always required engineering time and (often) hacks in Retool or Zapier. We had the thought experiment of “If we take a typical SOP, and make zero changes, how far can the LLM run with it?” and “What would we need in place to have everyone, eng included, comfortable with the end result in a critical path?”. And…

Hi HN! We’re building an open-source pricing & packaging engine for SaaS with a built-in billing system. (https://github.com/uselotus/lotus). We strongly believe pricing is the largest untapped growth lever for SaaS, primarily because pricing affects so many critical systems that don’t talk to each other (billing, payments, feature limits, metering, and CRM). We’re building this infrastructure to fix this and enable quick experimentation. Lotus acts as a central repository for all of your pricing plans and utilizes your payment gateway, to manage usage-based, per-seat,…

Paritydeals▲331Stripe is great, but is not simple. You end up handling many webhooks, mirroring Stripe data, tracking subscription states, and hardcoding feature checks. Managing upgrades, downgrades, migrations, overrides, and grandfathering often needs custom scripts. ParityDeals keeps that billing logic out of your app. Once you integrate ParityDeals SDK, you can manage everything from a single dashboard. No further code changes required. I'd love to hear your feedback

Credyt▲100Hey 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…
