Not vibe-coded. Engineered.

Demos got cheap.
Products didn't.

AI will get you a working demo by Sunday. Getting it through App Store review, in front of real users, and into a codebase you can still change next year is a different job. That is the job we do.

Four places this goes wrong.
Four ways we fix it.

Fixed scope, fixed timeline. You end each stage with something real: a written deliverable, working software, or both.

01
2 to 3 weeks · fixed scope

Productization

You have an idea, a spreadsheet, or a prototype nobody but you can use.

  • What the product actually is, and what it is not
  • Feature set cut to a shippable first release
  • Data model and integration map
  • Monetization and pricing model
  • Build plan and sequence

Deliverable: a product definition any competent team can build from.

6 to 12 weeks · fixed scope

Apps and Shops

You know what you want built, and you need it built properly.

  • iOS and cross-platform mobile apps
  • Web apps, dashboards and internal tools
  • Shopify storefronts, custom themes and store apps
  • Catalog, checkout, payments and fulfillment integrations
  • AI features wired into your own data
  • App Store submission and launch

Deliverable: a shipped app or store, with the code, accounts and docs in your name.

4 to 8 weeks · fixed scope

Production and Launch

You have something that works on your machine and nowhere else.

  • Auth, session handling and database access rules
  • Migration path and API cost exposure
  • Crash reporting and error handling
  • Storefront, checkout, catalog and payment flows if you sell
  • Subscriptions, paywall and entitlements
  • Privacy manifest and data disclosures
  • App Store review risk, submission and rejection response

Deliverable: a live product your customers can use and your next engineer can read.

Monthly · ongoing

Product Advisory

You have engineers shipping, and nobody deciding what.

  • Roadmap and release cadence
  • Scope control and cut decisions
  • Discovery practice your team can run without us
  • Design system and interface standards
  • Second opinion on the calls that are expensive to reverse

Deliverable: fewer wrong things built.
