> 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.)

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 (hello@infinite.red). Expect premium US rates - this is the partner for when your client's app is the product, not a brochure.
