About Dolphin
Summary
Dolphin builds full-stack web applications for startup founders who need a production-ready SaaS product fast. It generates a complete app, including database schemas, user authentication, billing, file storage, and an embedded AI assistant, from a single prompt. Founders get what would otherwise take an engineering team weeks: a correct, secure, and scalable codebase delivered in hours.

Go-to-market
Founders building their first SaaS product are the primary buyers, reached through the YC network and word of mouth. They start by describing what they want to build, and Dolphin ships a working app they can take straight to customers.
From the Y Combinator listing
Dolphin is a startup in a box.
Dolphin is a startup in a box. Dolphin is a web-app builder for aspiring startup founders to ship to their first customers in an hour. Dolphin builds startups in one pass. Dolphin can setup subscriptions, AI assistants, complicated database updates, integrations, messaging, and more. Teddy and I have spent thousands of hours building complicated web apps, and we’ve developed strong opinions on how to architect them. That’s why Dolphin is so powerful: rather than give an AI free rein, we constrain it to the Dolphin architecture. Constraints breed creativity. We designed the Dolphin architecture so that, when an AI works with it, its outputs are correct, secure, and scalable.
