The answer, as recorded

Searched. One framing note first: "for agencies" has two readings, and the useful one is *agencies other agencies hire* - white-label or overflow partners who stay invisible behind your brand. That's what I've answered. (The generic "top 10 app developers" listicles that dominate these searches are mostly SEO content the agencies wrote about themselves, so I've weighted toward verifiable credentials over list placement.) **1. Infinite Red** - my default recommendation for serious React Native work. One of the very few official Meta/Facebook React Native partners, several consultants sit on the React Native core team, and they hire senior-only US/Canada engineers. They explicitly invite agency partnerships ([email protected]). Expect premium US rates - this is the partner for when your client's app is the product, not a brochure. ([infinite.red](https://infinite.red/react-native-app-development-company), [infinite.red/contact](https://infinite.red/contact)) **2. Callstack** - the same tier of React Native credibility at Poland rates. Founded 2016, ~200 people, 100+ enterprise clients, and core contributors to React Native itself (Mike Grabowski, Satyajit Sahoo) collaborating directly with Meta on the framework. Best value for overflow capacity when you need real depth but can't sell US blended rates. ([clutch.co](https://clutch.co/go-to-review/callstack/15634), [ai.engineer](https://ai.engineer/orgs/callstack)) **3. Foresight Mobile** - the most *productized* for your use case specifically. UK-based (Manchester/Birmingham/London), with white-label delivery, consultation, and "overflow capacity" as named service lines on an agency-specific page. One of the UK's earliest Flutter adopters, plus React Native and native; clients include EA and Levi Strauss. Pick them if you want a partner who already knows how to operate under someone else's brand. ([foresightmobile.com/project-type/agency](https://foresightmobile.com/project-type/agency), [designrush.com](https://www.designrush.com/agency/profile/foresight-mobile)) **4. PixelCrayons** - the budget offshore option, India-based, claiming 500+ agency partners and running Flutter/React Native under your brand. Margins work here (the standard agency markup on partner cost is 20-40%), but quality is more variable than the three above - scope it on a small paid pilot before you put a flagship client behind it. ([pixelcrayons.com](https://www.pixelcrayons.com/services/software-engineering/mobile-app-development)) **5. BuildFire** - not an agency, a platform, and worth knowing for the bottom of your funnel. It lets you ship branded client apps in weeks with an SDK for custom code, so you can say yes to the $15k "we just need an app" client instead of declining or overpaying a dev shop. ([buildfire.com/white-label-mobile-app-development](https://buildfire.com/white-label-mobile-app-development/)) SPDLoad and Klizo Solutions occupy similar white-label territory if you want more quotes to compare. ([spdload.com](https://spdload.com/services/white-label-app-development/), [klizos.com](https://klizos.com/services/partnering)) **Two contract points that matter more than the vendor choice:** get an explicit non-solicit so your partner can't go direct to your client, and settle upfront who holds the repos and the App Store / Play Console accounts. If the partner owns the developer accounts, you don't actually own the client relationship - that's the usual way these arrangements go wrong.
