We're a collective of experienced developers who've built products and startups ourselves. We bring technical expertise and product thinking to founders solving real problems.
Senior developers
Who've built startups, not junior teams that need oversight
Start within 5 working days
No lengthy onboarding or red tape
Flexible pricing
Use us when needed, pause when you don't
Direct access
Work with Piotr and Kasia, no account managers
For non-technical founders, builders, and vibe-coders, we join you to move from POC to production with senior developer support.
02
We work best with founders who are serious about building real products
Building products with a small team, validating product-market fit, and needing technical leadership without a full-time CTO hire. You're moving fast and need someone who gets it.
Whether you can code or have a vision, you need help with architecture, scaling, or risk mitigation. You want partners, not subordinates. You value product thinking, not just code delivery.
Accelerate from idea to market validation with experienced builders who've been where you are. You need to move fast without creating technical debt that haunts you later.
Your vibe-coded prototype works. But the architecture won't scale. Every new feature risks breaking everything.
A junior dev needs oversight you don't have time for. A full-time CTO costs equity you don't want to give.
You need to move fast. But not recklessly. Build the foundation right now, scale confidently later.

We are Piotr and Kasia. We created Founding Developers to help founders with lack of technical structure, resources, or a full founding team.
Today's technology, especially combined with AI, makes it possible to validate ideas and build MVPs faster than ever. The challenge? Most founders operate in an uncomfortable "in-between" stage.

"I worked closely with Piotr and his team on the Fintech project, where they took the product from concept to onboarding the first users with exceptional execution. What stood out most was their strong product thinking; they understood the problem deeply, which allowed us to move fast with minimal documentation and friction. They operated like true partners rather than a typical delivery agency. I would confidently recommend Piotr to solo founders and teams looking to build and ship serious products efficiently."
"I had the distinct pleasure of working with Kasia across several large-scale projects. It is rare to find developers who not only deliver high-quality code, but also genuinely understand the business context and goals behind what they're building. Kasia consistently took the time to understand each project not just within its own scope, but from the perspective of the stakeholders — and that made a real difference in the outcomes. Every project was delivered to a high standard, on time, and often exceeding expectations. Aside from her obvious technical skill, Kasia was a genuine pleasure to work with — someone who took challenges in stride and brought a calm, solutions-oriented energy to everything she did. I cannot recommend Kasia highly enough. Should the need arise, I would not hesitate to work with her again."
We ship fast on technologies that last. AI eliminates repetitive work so our focus stays on the decisions that matter: your product strategy, architecture, and growth.
The first technical hire at a startup who makes critical architecture decisions, builds the MVP, and sets technical culture. We operate like one without requiring equity or a full-time commitment.
We join forces with other experienced developers from our network to form a team capable of handling larger projects, while staying lean and working under a split-revenue model where everyone cares about the company's success.
