Pairwise Tech

Pairwise Tech is a mobile studio of senior engineers who've already shipped the apps on your phone. Before founding the studio, our team built and scaled products at Shopify, Flo Health, Born, and Anima AI — apps used by hundreds of millions of people. We co-founded Anima AI, the AI-companion app, and exited it in 2023. Now we apply that experience to your app.


We do full-cycle mobile development. One team, one contract. The same senior engineers who scope your project also design the flows, write the code, ship the build, and handle everything around it: App Store assets and ASO, analytics, error tracking, retention work, and growth. No handoffs to junior teams. No agency layers.


What sets us apart:


– Senior-only team. Every engineer has 10+ years of mobile experience at apps like Shopify, Flo Health, Born, and Anima AI. No one is learning on your project.


– Design and engineering under one roof. We design with you — flows, screens, App Store creative — and bring in specialist design partners when the brief needs heavier craft. The people designing also build.


– Founder track record. We've launched, grown, and sold our own apps. When we talk about ASO, retention curves, and positioning for acquisition, we've done it ourselves with our own money on the line.


– Open-source and community credibility. Contributors to FlashList and React Native performance work. Program committee members at MobileOptimized.


We work with founders, product teams, and companies that want senior engineers to own the whole mobile stack — from the first wireframe to a shipped app that grows. Whether it's a brand-new product, a rescue project, or scaling an existing one, we've handled some version of it before.
