Sound familiar?

We hear these from founder after founder. Here's how we solve them.

Solution

We send you a CTO, not just developers. Every startup engagement includes technical leadership - architecture decisions, team building, and investor prep. You start with a team that already knows what it's doing.

“It is very difficult to find a software studio that can fully integrate with internal teams and take the project and responsibilities as their own, as Cookielab did. It's important for us to know we can rely on them, and that helps us every day.”

Jakub Šulta Co-founder & CEO, Carvago.com

Like Carvago, where we delivered a CTO plus a dev team and launched in 6 months

Solution

We don't just write code - we own the outcome. One of our founders leads your engagement personally and thinks about your product, not just the ticket. You get a partner, not a vendor.

Why startups choose Cookielab

It's not about ticking off tasks. It's about quality you can build a company on.

Full product ownership

All code, documentation, and IP are yours from day one. What we build is fully your asset - no hidden licenses or strings attached.

Equity partnerships available

For select startups, we invest time and expertise in exchange for equity. Skin in the game means we're as motivated as you are.

CTO included, not extra

Every startup engagement includes technical leadership by default. Architecture decisions, team building, investor prep - it's all part of the package.

AI-native development

Your project benefits from our AI workflows - faster delivery, better code quality, lower cost. The same tools and practices we use across all 50+ projects.

Built for continuity and independence

We hand over the know-how, clean and documented code, and train your team - so development keeps moving and you stay independent, no matter who's at the keyboard.
