we built a b2b saas in 81 days

this is how we did it (part 1)

we started building circular october 11th 2024

we had go-live with our first paying customer december 31th

how is that possible?

let's start with the tech stuff

we did a concious choice of not spending any time setting up our own infra

everything is serverless and as-a-service

and we're utilizing good, flexible, secure and future proof frameworks

this is our stack
🔮 framework: Next js
⚡️ database: Supabase
🔐 auth: Supabase
🚩 state management: TanStack
📋 ORM: Drizzle
📧 emails: Resend
💻 ui: Shadcn
✨ ai: OpenAI + Gemini
👨🏻‍🎨 design: Figma
⚫️ backlog: Linear
🛰️ hosting: Vercel
💶 payments: Stripe

to build fast without burning cash, we also used some different AI tools

that supercharges the development speed. Like having a large team of offshore devs at your fingertips

this is the AI stack
✔️ Generative UI: v0
▶️ IDE: Cursor
✨ Coding assistant: OpenAI o1
👾 Rapid prototyping: Databutton

this is the tech foundating we build upon to build at speed
