Firesale

We’re building Firesale — a platform where sellers create AI-powered listings by simply recording a video.
Buyers see beautiful, interactive posts generated automatically.
It’s fast, visual, and redefines how products are presented and discovered.

Everything is built with a modern, modular architecture — backend on NestJS microservices, frontend on Next.js, and a deeply integrated mobile app at the core of the product.

We’ve raised $1.5M in investment and secured an additional $500K in grants and credit programs from companies like NVIDIA, Google, Amazon, and others — giving us a solid runway and the ability to scale confidently.
