Founders Who Shipped
Service business owners who went from idea to live app in days.
Marcus T.
HVAC Business Owner
“I explained my scheduling idea in a 3-minute voice note. Three days later I had a fully working app with user logins, booking flows — everything. Would have cost me $40k at an agency.”
Priya M.
Consulting Firm Founder
“We loved it and jumped straight onto the weekly plan. Six months later we're shipping features every week.”
James R.
Fitness Studio Owner
“Our member portal has been live for 8 months. Zero downtime. The AI understood exactly what a fitness studio needs — member tiers, class bookings, payment history.”
Sarah K.
Restaurant Owner
“I went in skeptical. But it worked. The clarifying questions were smart — it caught things I hadn't even thought about.”

Most apps are live within 24 hours of our call, and 48 at the outside. Complex apps with many features may take slightly longer — we will tell you on the call if yours is one of them.
Tell us and we will fix it. The first build costs you nothing, so if it still is not right you can walk away without having paid us anything — that is rather the point of doing it this way.
Yes, always. The full codebase is yours. We push it to a private GitHub repo in your name from day one. If you ever leave, you take everything with you.
We specialise in service business apps — booking systems, client portals, scheduling tools, membership platforms, internal dashboards, CRMs, and workflow automation. If your business runs on manual processes, we can automate them.
Every app is built with Next.js (React), Supabase (database + auth), and deployed on Vercel. It is a modern, scalable stack used by thousands of production apps — easy to hand off to any developer if you ever need to.
Yes. Your app launches on a subdomain (yourapp.webappdev.co) so you can try it immediately. When you are ready to go live, we migrate it to your own domain — we handle the entire process.
One to two major features every week, and an engineer assigned to your project rather than shared across a queue. Scope is agreed before each sprint starts, and we keep building through the week rather than downing tools the moment a feature is done. Pause or cancel anytime — no lock-in.
Because it is the fastest way to show you we are worth $1,500 a week. You get the core of your app — up to 5 features, agreed with you as the must-haves for launch — live within 24–48 hours, and then you decide. Everything else you asked for waits in your backlog, ready to sprint.
You describe the app the way you would to a colleague — 20 to 30 minutes, no slides needed. We record it (with your permission) because the recording is what our AI turns into the brief and the build plan, which is how the build starts the same day. Want an NDA signed first? Just ask.
