Native or cross-platform?

Cross-platform with React Native and Expo for most products, which gets iOS and Android from one codebase. We go native for the parts that need it, such as hardware access or performance-critical screens.

Do you handle App Store submission?

Yes, including the privacy disclosures, screenshots, review guidelines and the back-and-forth with Apple and Google.

Can the app share code with our web app?

Usually. We structure the repository so the API client, business logic and design tokens are shared, and only the screens differ.

Startups between inception and pre-seed can work with us on sweat equity or a payment plan. From seed to Series A, plans start at $999 a month and scale with the team you need. Enterprise work is scoped and priced per engagement.

[ 03 ]Four phases

Process

Fourphases,runthesamewayeverytime.

The same methodology every venture in the studio runs on, from thesis to market.

01
Illuminate
Vision and market truth
We pressure-test the thesis before a line of code exists — market, wedge, buyer, and the uncomfortable question nobody has asked yet.
02
Architect
Roadmap and foundation
We design the technical and commercial foundation: stack, data model, unit economics, and the sequence that gets to proof fastest.
03
Forge
Build and iterate
A permanent studio team ships the product in tight cycles. Shared infrastructure means you inherit years of groundwork on day one.
04
Ascend
Launch and scale
We take you to market, support the raise, and stay on the cap table — aligned with the outcome rather than the invoice.
