YC S25

About the Company

Floot is building the AI-first software foundation for non-coders to build and deploy full-stack web apps. We grew from 5 to 600+ paying customers during YC! 🚀

Unlike other platforms that cobble together dev tools, we're rebuilding the entire software stack for a world where AI writes most of the code.

Our goal: Make Floot the default choice for anyone to build and ship software.

Our founders are staff engineers from Retool and AWS. Edward (CTO) bootstrapped his last SaaS company to $5M+ ARR in one year.

Tech Stack

Floot is an all-in-one platform with the entire tech stack built-in (backend, database, hosting, etc).

Our stack:

Node.js
TypeScript
React

Deployment:

AWS (Lambda, Cloudfront, S3, etc)
Neon databases

What we've built:

Custom AI-first coding framework
Custom sandbox for AI-generated code
Custom runtime that runs in frontend and backend
Custom deployment infrastructure
Multi-model agentic system with advanced debugging capabilities

We're optimizing every layer of the stack for AI.
