We ship the products founders actually want to launch.

Mobile apps, AI-powered services, and the backend that makes them real. Built by a small senior team that’s already shipped on the App Store.

From the screen the customer taps to the server that takes the payment.

How we work

A short, honest process.

No discovery theatre. No vague time-and-materials forever.

01

Discovery

30-minute call. We listen. You get an honest recommendation — even if it’s “don’t build it yet.”

02

Scope & quote

Fixed-fee or weekly retainer with a written scope. No vague T&M forever arrangements.

03

Build

Short weekly demos. Code in your GitHub. You own the IP from day one.

04

Ship

App Store, Play Store, or web. Plus a one-month no-cost warranty after launch.

Tech we use

Boring stack. Shipped outcomes.

Mature tools. No frameworks-of-the-week.
