First week

Get aligned and start building

Learn & Plan

We learn your goals, users, and what the first version should include. Designs start in Figma.

Set Up the Team

We set up the code and tools. Your engineers join Slack and know exactly what they're building.

First Demo

By end of week one, you see real working code — not just slides.

Weeks 2–4

Build features and move fast

Weekly Sprints

Clear goals every week. You always see progress you can demo.

Build Features

We build the frontend and backend — React, Node, Python, or whatever your stack needs.

Test Everything

We test before every release so nothing breaks for your users.

Daily Check-ins

Quick updates every day. Problems get fixed the same day.

Demo for Investors

Polished demos ready for investor meetings or customer reviews.

Weeks 5–8

Launch and grow

Go Live

We put your product live with monitoring so it stays up and running.

Fix & Support

We fix bugs and make updates after launch — same team, no handoffs.

Speed & Security

We test speed and lock down login before you get more users.

Add More Help

Need more hands? We add engineers as your product grows.
