Modelence
YC S25Build production-ready apps with AI
About
You built the demo in a weekend. Now you need auth, a prod-grade database, real-time events, AI observability, cron jobs, email, monitoring… and you needed them yesterday. We spent a decade at our previous startup, building a $500M platform while scaling to millions of users and customers like Meta & Netflix. Now we're standardizing how web applications are built with an open-source framework and AI App Builder, so non developers can build reliable production apps and not just prototypes. Modelence is a batteries-included platform with a dedicated web app framework that's designed for building production grade apps with AI, abstracting away the standard building blocks: - Authentication - Database - Hosting - AI integration - Cron jobs - Live / real-time data - Email integration - Monitoring Most AI app builders just stitch together multiple services and existing frameworks. The reliability drops hard because integrations between different parts break. Modelence defines a single full-stack framework with dedicated cloud infrastructure, where these integrations are already built into the framework and don't need to be built for every app.
