Margelo’s depth is real and publicly verifiable, which is rare in this industry. Their founder created VisionCamera, the de-facto standard camera library for React Native, the agency maintains an open-source ecosystem with millions of downloads, and the published client work includes Discord’s new-architecture migration and camera features for VSCO. At the bleeding edge of React Native internals, JSI, native modules, frame processors, they are likely the strongest team in the German-speaking world, and we say that without flinching.
Look at the shape of those engagements, though: a module, a migration, a performance problem, handed to specialists by teams that already have a CTO, a product organisation, and a working app. That is the job Margelo is optimised for, per their own case descriptions, and mobile is the published scope.
Our job is wider and less glamorous: the whole product. Backend, web, the mobile app, the AI features, the product call, and the pushback when a feature should not ship. We build React Native too, and we will happily use Margelo’s open source when it is the best tool, because it often is.
If you have a CTO and a React Native performance problem, go to Margelo. If you have a product problem that happens to include an app, see how we build mobile products.
