We build, protect, and scale React Native products that survive due diligence and growth. so you don’t pay for the same app twice.
Whether your code was written by AI tools, offshore developers, a founding engineer who left, or your co-founder learning as they go. the problem is the same: you’re shipping fast, but nobody is asking whether you’re shipping right.
The mistakes that kill startups aren’t bugs. They’re decisions: the wrong architecture, the wrong database, the wrong framework, the shortcut that saves a week now and costs six months later.
That’s where we come in, not just to build, but to make sure what gets built can actually survive what comes next.
Three engagement lanes depending on where you are. all anchored in technical judgment.
Most teams build what you ask. We build what you actually need. and push back on the rest.
For founders who want a team that thinks like owners, not order-takers.
Your codebase is a liability you can’t see. We audit the decisions that will cost you later and give you a clear plan.
For teams shipping fast who need a second set of eyes before it’s too late.
You’ve got momentum. Now you need a technical partner who can grow with you and tell you what not to build.
For companies doing $500K-$5M+ in revenue who want ongoing leadership without a full-time CTO.
Choose React Native if:
These aren't small apps. These are apps that handle scale better than most native apps.
We turn down clients when React Native isn't the right fit. Here's when you should build native instead.
We've built both. We'll tell you which makes sense for your stage and budget. Most pre-Series A startups pick React Native. Most Series B+ startups still use React Native.
We'll analyze your needs and recommend the right approach.
Most agencies build React Native apps like websites. We build them like production systems that pass technical due diligence.
When VCs audit your code, they check if your business logic lives in React components. If it does, they see a mess that can't be tested or maintained. Our architecture keeps business logic separate, testable, portable, and investor-ready.
We'll show you how clean architecture helps you pass due diligence.
We use Expo for 90% of our projects. It's not a limitation, it's a superpower.
You find a critical bug on Friday night. With native apps, you submit to app stores and wait 24-48 hours. With Expo Updates, you push a fix in 20 minutes. Users get it automatically.
Camera, location, notifications, sensors, all work without writing native code. No Xcode. No Android Studio. Just TypeScript.
Hot reloading that actually works. Instant preview on real devices. Share builds easily. Ship features 2x faster.
New iOS or Android version? Update one package. Done. Native projects break on every OS update.
PicklePlay found a crash affecting 15% of users on Friday night. We pushed a fix via Expo Updates in 20 minutes. By Saturday morning, 98% of users had the update. No app store submission needed.
Ship faster and deploy fixes instantly with our Expo expertise.
We use the same stack for every React Native project, not because we're lazy, but because this stack actually works at scale.
Type safety catches bugs before production. IDE errors as you type. Safe refactors. Faster onboarding.
Redux requires 200 lines of boilerplate for simple features. Zustand does it in 20 lines. Clean, readable state.
Why we don't use Redux:
TypeScript checks types at compile time. Zod validates data at runtime. API returns invalid data? Zod catches it. Type-safe end-to-end.
This isn't theoretical. PicklePlay went from 30% crash rate to 0.8% partly because we validate everything with Zod.
Slow apps kill retention. We've optimized React Native apps from 8-second startup to under 2 seconds. Here's how.
We'll audit and improve your app's performance.
Founders ask us about Flutter. Here's what we tell them.
Flutter is great technology. But React Native wins for most funded startups because of ecosystem, hiring, and Expo's over-the-air updates.
Apps with poor test coverage fail technical due diligence. We implement testing that catches bugs before users do.
VCs review your test coverage during due diligence. Apps with <50% coverage raise red flags. We get you to 80%+ so you pass.
We'll set up comprehensive testing that passes due diligence.
One security vulnerability kills your funding round. We implement security that passes audits.
Your Series A investors will request these documents. We make sure you have them.
PicklePlay had 10K users but their app was broken. Crashes hit 30% of sessions. Reviews averaged 2.8★. Poor architecture made every new feature take weeks.
We rebuilt their React Native app from the ground up. Implemented Zustand for clean state management. Built a new Python backend with proper API design. Added Sentry for error tracking and fixed root causes systematically. Reduced crashes from 30% to under 1%.
Crash rate:
30% → 0.8%
App rating:
2.8★ → 4.5★
Users:
10K → 200K
Exit:

"Vermillion rebuilt our app in 12 weeks. We went from losing users daily to 200K active users. UTR acquired us shortly after."

If you nodded at even one of these. let’s talk. The first call is free and there’s no pitch.
Free 15-minute strategy call. No pitch, just clarity.
Most dev shops are order-takers. We review the plan, challenge assumptions, and build with the full picture in mind. You’re not paying for code. You’re paying for judgment that saves expensive mistakes.
That’s fine. We do plenty of straight development work. with one difference: we’ll still flag risks and push back on bad decisions. That’s not an upsell. It’s how we work.
Yes. Start with a free 15-minute strategy call, then choose the lightest engagement that makes sense. Most clients start small and expand once we prove value.
Yes. Instagram, Discord, Shopify, and Microsoft use React Native in production. Billions of users interact with React Native apps daily.
Yes. We've built marketplace, fintech, health, and social apps. React Native scales to millions of users.
React Native performs close to native for most use cases. We've optimized apps to 60fps scrolling and sub-2-second load times.
Expo provides over-the-air updates, easier testing, and faster development. We use bare workflow only when you need custom native code.
Zustand requires far less boilerplate with the same functionality and cleaner code.
MVP: 8-12 weeks. Full product: 16-20 weeks. Faster than native because you ship both platforms from one codebase.
Book a free 15-minute strategy call. We'll review your requirements and tell you if React Native is the right choice, plus the roadmap to scale.
No pressure. No sales pitch. Just honest advice from engineers who've built React Native apps for 9 years.
