Your SaaS idea becomes a product customers pay for monthly — in 90 days.

At CPI, architecture, data model, and code reviews are handled by a human who has been building software for almost ten years — AI speeds up writing the code, not making the decisions. So you don't need a CTO or your own dev team to get started. And if the product takes off after launch, you can bring Maximilian Schmidt into the company as CTO in exchange for equity — as with several of the ten-plus companies in the CPI portfolio.

Yes, that's standard in our SaaS projects: multi-tenant architecture, roles and permissions, subscription billing, and onboarding are part of the scope from day one — on the same stack as our own products (Next.js, NestJS, Keycloak). Hosting is in the EU, GDPR-compliant, on accounts that belong to your company. You get a full breakdown of all services and running costs at any time — there's no lock-in that only we can undo.

Not necessarily. We look at what you have and tell you honestly what's viable: sometimes we build on it, sometimes a clean rebuild is faster and cheaper than patching — especially when multi-tenancy or billing needs to be retrofitted. That's exactly how Vacabee came about: a bare-bones prototype became a full-fledged AI app with iOS, Android, and web versions. You get that assessment in the free Potential Analysis — before you commit to anything.

The quote costs you nothing: in the free Potential Analysis, we find out together whether your SaaS idea has legs. You then receive a written fixed-price quote with scope and launch date. Once you sign, that number doesn't move — no matter how many hours we put in. Anything you want later, like new modules or integrations, gets its own quote; the live product stays untouched.

You do, 100%. Source code, credentials, documentation, and the hosting and service accounts all run under your company's name. That's exactly what investors check in every due diligence — and with us, there are no surprises. We keep supporting the product after launch, but a complete handover to your own team is possible at any time: if you never hire us again, you're not missing a thing.

Then you'll know after two weeks instead of after a year. In stage 1, we talk to five people from your target audience — if the idea doesn't hold up, we end the project right there and you only pay for that stage. You receive the interview results and our written reasoning. That's the cheapest lesson you can get in a SaaS project — far cheaper than a finished product nobody uses.
