You have the idea. I'll build the prototype.
I'm a solo developer who helps non-technical founders turn their app ideas into real, working prototypes — fast. No jargon, no bloated agency process. Just a conversation and a build.
Idea in
30-min call
Prototype out
in weeks, not months
How It Works
Three steps from idea to prototype
A clear, straightforward process — no surprises, no runaway timelines. You stay informed, I handle the building.
Tell me your idea
We start with a free 30-minute call. No prep needed, no pitch deck required. Just tell me what you're imagining — I'll ask the right questions.
We scope it together
After the call, I'll put together a clear plan: what we build, what it does, and what it won't do yet. You'll know exactly what you're getting before anything starts.
I build it, you run your business
Once we're aligned, I get to work. You don't need to manage me or translate requirements into tech. I check in regularly and hand over something you can actually use.
What You Walk Away With
Not just code. A prototype you can use.
The goal isn't to ship lines of code — it's to give you something real you can put in front of people.
Who This Is For
This is for you if…
I work best with individuals and small teams who have a clear idea and want to move fast.
Great fit
- You have an idea for an app but you're not a developer
- You've tried explaining it to a tech person and felt lost in the conversation
- You want to validate the idea with something real, not a pitch deck
- You're a founder, freelancer, or small business owner building something new
- Speed matters — you don't want to spend months to find out if it works
Not the right fit
- Large teams or companies that need full engineering staff
- Agencies looking for white-label work
- Enterprises with lengthy procurement processes
The Builder
Hi, I'm Thilo
I'm a developer who got tired of watching great ideas die because the person who had them couldn't find the right technical partner. I started Prompt Launch to make that first step easy — a real conversation, a real plan, a real prototype.
I use modern AI tools to build faster than traditional development — which means lower cost, quicker feedback, and less time spent waiting to find out if your idea works.

Outcomes-based self-checking lets coding agents judge whether they achieved the goal before handing work back. It's the feature that makes autonomous coding scale — and the one most likely to give you confident, wrong results if you're careless.
Dynamic workflows spawn parallel agents to tackle big jobs like migrations in hours instead of weeks. The speed is real. The thing that decides whether you wake up to a finished migration or a mess is how you prepared the job.
The monorepo vs. multi-repo debate consumed engineering conferences for years. By 2026, the answer is clearer than the debate suggested. The decision points are specific, and most teams that have actually tried both have converged on patterns that work.
The traditional side-project trajectory was: build for a year on weekends, launch to crickets, abandon, repeat. The 2026 trajectory is different. Indie hackers are reaching profitability faster, and the reasons aren't entirely the obvious ones.
TypeScript and AI-augmented coding have a stronger pairing than either does alone. The type system catches AI mistakes that pure runtime testing misses. The AI handles the verbosity that made TypeScript painful. The combination is more productive than either tool alone — but only with specific patterns.
Schema migrations have always been the part of software engineering that ages worst — risky, hard to test, easy to get wrong. AI-augmented migration workflows in 2026 reduce the pain substantially. The patterns are clear enough to recommend.
