We own the results – systems that scale, and last
We don’t just ship code. We build with care, ask the hard questions, and stay accountable for the outcome.
We’re a boutique team of engineers, consultants, and long-term partners. Every project we take on is treated like it’s our own: designed with clarity, built with discipline, and shaped by a genuine interest in how things work – and how they’ll hold up over time.
Whether it’s an enterprise-grade WordPress platform, a custom ecommerce system, or an AI-native app, our approach stays the same:
- We listen closely.
- We build responsibly.
- We stay flexible.
- We keep things honest.
Because we believe that trust is earned not just in how we communicate – but in what we deliver.
Andrzej Martens
Co-founder, CEO
I have been involved in organizing, managing, and developing IT projects since 2012. I have extensive experience across domains such as commerce, services, e-commerce, e-learning, e-marketing, fintech, and the medical industry. I help structure projects and ensure their alignment with clients’ business processes.
Maciej Kostecki
Co-founder, CRO
I have 24 years of experience and more than 300 projects to my name. I understand user needs as well as the strategic and operational aspects of business. I know which solutions are effective and which will lead to problems or unnecessary costs.
I’m curious to know what goal you want to achieve.
What Drives Us
1
Ownership
We take pride in what we build – and responsibility for how it performs.
That means sweating the details, not just hitting deadlines.
Thinking ahead, not just ticking boxes.
And making sure your system works not only today, but a year (or three) from now – even if someone else takes it over.
“We treat your product like it’s ours.”
2
Flexibility
We don’t believe in lock-ins or rigid processes.
If you need to change scope, pause, pivot or quickly scale effort up or down, we adapt.
Short onboarding keeps things moving fast, flexible billing models fit your situation, and short termination periods mean no heavy commitments. You can also pause the project whenever needed.
You work directly with the people building your product, so decisions happen quickly and without layers of bureaucracy.
And we never force a single workflow, we shape the process around how you like to work.
Pause for a bit? Shift scope? No problem. We are built for it.

Quality
To us, quality means fewer surprises down the road.
We use checklists. We automate. We test. We clean up after ourselves.
It’s not about perfection.
It’s about craftsmanship – the kind that shows when things get tough and timelines get tight.
“We don’t cut corners. We clean up after ourselves.”
4
Integrity
We tell the truth – even when it’s inconvenient.
If something’s going well, you’ll know.
If it’s not, you’ll know that too.
We don’t hide behind roles or hide mistakes.
We take responsibility, learn, and fix.
That’s how trust is built – and how real collaboration works.
“No hiding behind roles. No corporate theatre.”
5
Curiosity
We ask questions. Sometimes a lot of them.
Not to challenge – but to understand.
Because when we really get what you’re building (and why), we can make better decisions, avoid missteps, and build something that truly fits.
“We ask a lot of questions – because we want to get it right.”
