From idea to marketable prototype in 14 days.
You have a startup idea, funding in the pipeline, or already have your first investors on board. Now you need proof: Does the concept really work? Will users pay for it? What exactly needs to be optimized?
The problem: Traditional agencies take months and burn through six-figure budgets for MVPs that ultimately fail in the market. Internal teams get bogged down in technical details. And no-code solutions? They look like no-code solutions.
Business Validator solves this problem differently: I build you a functional, professional prototype – complete with branding, your own domain, and all the tools you need for real market validation. Not in 6 months. In 2 weeks.
What you get
A launch-ready prototype that really works. No click dummies, no half-baked concepts. A real product that users can test, with which you can collect data, and which you can show to investors.
Complete branding – if necessary. Logo, color scheme, typography, naming. Everything that makes your product look professional. If you already have a brand setup, I’ll work with it. If not, I’ll create one.
Live on the web, under your own domain. Not only on your computer, no demo links. Your prototype is publicly accessible, stably hosted, and ready for real users.
Technically ready for market tests. Analytics integrated, A/B testing prepared, Google Ads-compatible. You can start running campaigns and measuring what works right away.
Everything from a single source. No downtime between designers, developers, brand managers, and project managers. One person who understands how everything works together. This eliminates friction losses and makes all the difference in speed.
Who is it for?
For well-founded startups that want to validate quickly. You have a budget, a clear concept, and want to prove that it works—before investing hundreds of thousands in full development.
For founders with investors behind them. You need figures for the next funding round. Or your VCs want to see if the product-market fit is really there.
For corporate innovation labs. You’re testing new business models, but you don’t need six-month agency projects for every trial balloon.
For anyone who has a marketing team, but no prototype team. You know how to attract users. You just need a product for them to test.
Why so fast?
Because I eliminate the typical agency madness. No endless rounds of coordination between five departments. No weeks of waiting for the designer, who is waiting for the developer, who is waiting for the brand manager.
I do everything by myself: design, development, branding, technical setup. That means I understand your vision from the very first conversation, translate it directly into a functioning product, and don’t have to explain three times why the button color is strategically important.
On top of that, I have my own AI tool. It’s a tool I developed myself that speeds up repetitive tasks enormously – from code generation and design variants to setup automation. This is not a standard ChatGPT solution, but a framework that I have optimized for precisely these prototyping processes.
The result: professional quality in a fraction of the time. And significantly cheaper than what agencies would charge for it.
What happens next?
The prototype is yours. You can now get started: run marketing campaigns, set up A/B tests, collect user feedback, analyze metrics. Or just tell me what you want to test and I’ll set it up for you.
I provide you with the tools for your market validation—you decide how to use them. Whether you continue to build internally, hire an agency, or go through another round of improvements with me.
How does it work?
1. Initial consultation (free of charge)
We clarify whether your idea can be implemented with web technologies and what exactly you need.
2. Briefing & Concept
You tell me your vision, I sketch out what the prototype will look like. We agree on the scope and timeline.
3. I build
You receive regular updates and can provide feedback—but I won’t bother you with daily stand-ups.
4. Launch
After ~2 weeks (depending on complexity and your availability), the prototype goes live. You receive all access details and can get started right away.
Ready?
If you have a clear idea and don’t want to wait months for someone to implement it, let’s talk.
