How We Work

Step 01

Discovery Call (Week 1)

We listen more than we talk. What problem are you solving? Who uses this? What keeps you up at night? 

Step 02

Project Blueprint (Week 1-2)

Detailed scope, timeline, and fixed-price quote. No "we'll figure it out as we go" nonsense.

Step 03

Design & Prototypes (Week 2-3)

See your app before we write a single line of code. Iterate until it's right. 


Step 04

Development Sprints (Ongoing)

Working features delivered every 2 weeks. You see progress, give feedback, we adjust. 

Step 05

Testing & QA (Throughout)

We break things so your users don't have to. Security, performance, edge cases—covered.

Step 06

Launch & Beyond

We deploy when it's ready (not when the calendar says). Then we stick around for support, updates, and growth.

Questions  

We Get Asked


Honest answer: 8-16 weeks for most projects. Rush jobs cost more and usually turn out worse.

Yes. We've rescued more projects than we've started from scratch.

Absolutely. Your idea is safe with us.

We include 30 days of free adjustments. After that, support packages or hourly rates. 

It's YOUR code. We hand over everything—documentation, passwords, the works.
