For non-technical founders, builders, and vibe-coders, we join you to move from POC to production with senior developer support.

02
Every new feature is a risk. Deployments happen in slow motion. You're terrified of breaking what matters. Users are hitting reliability issues. You're shipping slower, not faster.
And you know what's coming next. You're not ready for what it usually costs.
The problem
02
The next level requires different skills. Your focus needs to be somewhere else.
Hiring a junior slows you down. A senior developer is hard to find or you can't afford one yet fulltime. A cofounder is a major bet.
So you stay stuck.
The answer
03
There's a third option
We're senior developers who actually work in early-stage startups. We don't over-engineer. We understand that "perfect" is the enemy of "shipped,"
but at the same time, we lay solid foundations so you can grow into a fully fledged product—with the right architecture, security, and industry-standard code.
Work with us →01
Pay only for the days you need. Use us when it makes sense, pause when it doesn't.
Get senior-level technical oversight without committing to a full-time team.
It's like having experienced founding engineers in your corner—helping you navigate technical decisions, trade-offs, and execution as you grow.
Starting from 5 working days

"Turn our vibe-coded prototype into a production-ready full-stack app."
"We need to build fast from our service blueprint so we can start onboarding customers."
These are common starting points—but we're not limited to them. We use our technical expertise to help founders take the next big leap: turning a validated idea into a real, scalable business.
Starting from $2,000 engagements
What changes
04
Direct access to developers with 8+ years of experience—people who understand fast-scaling startups, not just code. You get ownership and urgency, not contractors punching a clock. We treat your roadmap like it's ours.
No long-term commitment. No CTO search. Engage us part-time or full-time, for as long as you need. You get senior talent on your terms—without the overhead of hiring a founding team or managing a permanent headcount.
Proven stack. Proven operations. We keep options focused to popular technologies that scale. More importantly, we've built and run production applications—we know monitoring, scalability, and security aren't afterthoughts.
Easy transition when you're ready to hire. We handle onboarding and hiring support, then step back. You keep the momentum, the codebase, and the clarity—we stay available for consultancy as needed.
We reuse strategically, moving you gradually toward production-ready. No shortcuts. No premature abstractions. The code you inherit is the code you can actually maintain.

We are Piotr and Kasia. We created Founding Developers to fill a real gap in the early-stage startup ecosystem — where creative builders and problem-solvers want to create digital products that solve real problems, but lack 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 — without needing a full engineering team from day one. Yet many founders operate in a "in-between" stage:
Traditional options don't fit this stage well. Software houses are not designed for early-stage realities. Agencies deliver developers, not product thinking. What early founders actually need is flexibility, speed, strategic tech decisions, and the ability to move fast without creating future technical risk.
That's why we built Founding Developers — a boutique collective offering the way of working of an experienced Founding Engineer, delivered in an agency model.
What founders say about us
"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. The team was highly punctual, reliable, and consistently delivered on time. 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, effectively acting as a founding engineering team. I would confidently recommend Piotr to solo founders and teams looking to build and ship serious products efficiently."
