Pat asks for transparency on the numbers — and Eyal delivers. [1] — Eyal "~50% profit margins: PropGPT runs at roughly 50% profit margins after accounting for marketing, data APIs, hosting, and tooling costs." 09:15 PropGPT is built on a React Native codebase with TypeScript and Python powering the machine learning algorithms and automated data fetching. The database runs on Neon at $10/month, RevenueCat handles subscription management at 1% of revenue, and Superwall manages the paywall at $0.20 per conversion. Real-time sports data APIs cost roughly $100/month, and LLM costs — despite the AI-heavy product — are just $20/month and falling. The biggest cost by far is marketing at $10,000/month, predominantly influencer campaigns. After all that, margins sit at approximately 50%, a strong return for a two-person college startup in a competitive, data-intensive vertical.
