No technical co-founder?
No problem.
I build your MVP in weeks — no equity, no €25k agency quote. Fixed price per milestone, and after the first one you decide if we continue. No strings attached.

A technical co-founder wants half your company.
Meanwhile, your idea sits in your notes app — while someone else is building theirs.
There's a third option.

Hi, I'm Brani 👋
I'm the founder of Rapivio and a Business Information Systems student at Uni Hohenheim in Stuttgart. For over two years, I've been building mobile apps with FlutterFlow and Flutter — for my own projects and for founders who want to validate ideas fast.
I believe great apps don't have to be expensive or complicated.
Milestone by milestone.
Never a blank cheque.
Every project is different — so every project gets its own price. But you see the whole number before I write a single line of code.
FREE · BEFORE ANYTHING
The Blueprint
I map your user flows, data model and screens. It's yours to keep — whether we build together or not.
FIXED, IN WRITING
A price per milestone
The blueprint splits your app into 2–3 milestones. Each gets a fixed price and a delivery date. You see the total upfront.
NOTHING HIDDEN
40 / 60 per milestone
40% starts the milestone, 60% when it's delivered and you've seen it working. No invoice you didn't agree to.
How a milestone is paid
Two payments. Both agreed before it starts.
The larger half only moves once the work is on your screen — so I carry the risk of delivering, not you.
Risk-free checkpoint
After the first milestone, you decide if we keep going.
No notice period, no penalty, no conversation you have to talk your way out of. You've seen how I work, how I communicate and what I ship — and if it isn't right, you walk with everything built so far. The code, the designs, the blueprint. All yours.
30 minutes · You leave with a rough scope and a real number
From idea to app in 4 steps
Discovery call
We talk about your idea, goals, and scope. 30 minutes, free, no strings attached.
Plan & design
I map out user flows, data model, and create a clear project plan with a clickable design. You see exactly what's being built before development starts.
Build & test
I build your app in short sprints with regular updates. You test along the way and give feedback. After the first milestone — you decide if we continue.
Beta & launch
Final testing, beta phase with real users, then App Store submission and go-live. After launch: support as needed.
