From Idea to
Launch in Weeks.
DEVLN builds MVPs and apps for non-technical founders with fixed price, fixed timeline, and no surprises. Mobile, web, and AI features, built by a UK-registered team. You own 100% of the code.
How We Work
Two ways to work with us, one engineering team behind both.
MVP & Product Development
Have an idea but no technical team? We take you from concept to live product: design, development, launch, and 3 months of free support. Fixed scope, fixed price, and weekly demos so you always know where your money went.
Live in 4-8 weeks
Fixed price agreed before we start
You own all code and IP, no lock-in
White-Label Development
Marketing, design, or web agency with dev work you can't handle in-house? We build under your brand: apps, web, and AI features. NDA signed, your client stays yours, and weekly reports keep you in control. Start with a flat-fee trial task to test us risk-free.
Your brand, our engineering
