Modelence is a Y Combinator S25 startup offering a full-stack, batteries-included platform for agentic development with TypeScript. It abstracts away production boilerplate by providing authentication, databases, hosting, AI integration, real-time events, cron jobs, email, monitoring, and admin dashboards so teams can focus on product logic. The company is founded by Aram Shatakhtsyan and Eduard Piliposyan, who previously built and scaled CodeSignal (valued around $500M). Modelence is based in San Francisco and partners with MongoDB.
