For founders and companies with a product idea
Most SaaS ideas do not fail because of the idea but because teams spend too long building features nobody needs. That is why we start with a lean MVP that real users can try and pay for.
You do not get a throwaway prototype but a clean foundation with login, multi-tenancy, billing and an admin area that your product can grow on.
- Founders who need an MVP for first customers or investors
- Companies that want to sell internal know-how as software
- Existing products that need to be rebuilt
- Teams looking for technical capacity without a hire

What founders want to know
Does this fit your project?
Describe briefly what you have in mind. You will get an honest assessment within one business day.
What is an MVP?
A minimum viable product is the smallest version of your product that lets real users solve a real problem. It shows quickly whether the idea holds before much money goes into features.
How much does it cost to build a SaaS?
SaaS development starts at €9,999. After the product workshop we agree on a fixed price for the MVP before development starts.
Do I own the source code?
Yes, completely. That matters for later investors and your own developers. You are not tied to KSTAQ.
Which technology do you use?
Proven, widely used technology: TypeScript, React and Next.js, PostgreSQL as the database and hosting that scales with you. That makes it easy to find more developers later.
