ThreeBinaryUnits · Product & Engineering Studio

Real software. Not just promises.

We build working SaaS products, MVPs and custom systems that you can try before you talk to us. Use our solutions as they are, customize them for your business, or let us build something new from scratch.

app.tsx
'use client'

// Live demos — try before you buy
import { launchDemo } from '@threebinaryunits/demos'

export function YourProduct() {
  return launchDemo({
    mode: 'use-as-is',
    customize: true,
    buildNew: true,
  });
}

How We Work

Customize
Like one of our products, but need different workflows, integrations or features? We adapt it to your business.
Build From Scratch
Need something completely specific? We design and build custom software from zero to production.
Join Your Team
Already have an internal system or development team? We can join your project and help with architecture, frontend, backend, databases or integrations.

Our Team

People who build — and still enjoy it

We are a small studio that still enjoys opening an editor after hours — shipping products for clients and tinkering in the lab because we like how software is made.
