Studio
A product studio for privacy-first Apple software.
Keelwright builds focused products where the privacy promise, platform choice, and business model have to hold together.
Data boundary first
Define what stays on device, what syncs through the user's account, and what needs product-operated infrastructure.
Native when it matters
Use SwiftUI, SwiftData, HealthKit, widgets, watchOS, CloudKit, and App Attest when Apple-native capabilities strengthen the product.
Proof over posture
Turn each shipped product into a readable case study with architecture, trust model, and user outcome made explicit.
Who this is for
Founders and operators use Keelwright as a reference point for products where trust is part of the UX: consumer Apple apps, private AI workflows, product-led web tools, and edge security for mobile systems.
Explore the work
The portfolio is the main conversion path: start with shipped products, then contact the studio when the fit is clear.
Products that prove the method
Case studies across the public portfolio, including products still waiting on a first crawl.
