Your app needs to work for real customers, not just your test accounts. Scale to millions of transactions and keep improving revenue and retention after launch.
Few app development agencies can do all three. They specialise in one thing only. We validate your ideas with researchers, build systems handling 40,000 API calls per second, and proactively optimise apps for growth. All in-house.
Veezu: 13-years, £100m app revenue. Carbs & Cals: 8 years, 21x growth.
In-house user researchers.
Surprising how often "everyone in the room agreed" doesn't match what real users want. Our in-house researchers test prototypes with actual users before we write code. We watch them struggle, ask why, and validate every decision. Your board gets confidence you're building something that works in the real world, not just in meetings.
Ready for millions.
Your app hits product-market fit. Great. Now you need it to handle 50,000 users. Then 500,000. We build systems that scale (we handle 40,000 API calls/second for Veezu). And we optimise for growth; app store presence, retention loops, the works.
In it for years.
The agency you brief today is rarely the partner you have 18 months later. Different team. Lost context. You're explaining everything again. We stick around. 13 years with Veezu. 8 years with Carbs & Cals. Same team who knows your business, your users, and why certain decisions were made. When we structure partnerships, we consider revenue-share, equity, or standard terms because we're genuinely invested in this working.
