    About me

    Fifteen years in fast-growing companies

    For fifteen years, I worked on the operational side of fast-growing companies: from my own startup, through roles as COO and CGO, to CDO at uPacjenta during its PLN 21 million seed round.

    Today, I help founders of 10–50 person companies organize their structure, focus priorities, and scale growth without uncontrolled team expansion.

    My Experience

    Five companies, five different stages, one recurring lesson.

    2012–2013

    Software Quality Assurance & Management

    Sales Specialist → Team Manager

    My management path began here after a few months as a sales specialist. The promotion brought sudden responsibility for a team of over a dozen people—my first lesson in managing people and performance simultaneously.

    2013–2019

    GEMS Interactive

    Co-founder & CEO

    I ran this company for nearly seven years. It's where I learned what it's like to build a business from scratch, where you are responsible for almost everything yourself—from sales and product to finance.

    2019–2020

    RIOT

    Head of Business Development → COO

    I joined as Head of Business Development and was promoted to COO within a year. This was a lesson in rapidly transitioning from business development to full operational responsibility, integrating teams and culture as the studio became the digital hub for Diagnostyka S.A.

    2020–2023

    uPacjenta

    Head of Growth → CGO → CDO

    I went through the full growth journey with the company. I joined in 2020 when the company had an annual revenue of PLN 1.78m; by the end of 2021, revenue reached PLN 20.51m. I built sales and data structures from scratch, managed teams responsible for multi-million revenues, and oversaw burn rate and forecasts. I participated in securing one of Poland's largest seed rounds—PLN 21 million.

    2023–2025

    Wellbee

    Head of Commercial

    The last two years were spent at Wellbee as Head of Commercial, until its acquisition by Benefit Systems. This was a lesson in commercial scaling within a company heading for an acquisition.

    Five companies, five different stages, one recurring lesson

    Rapid growth multiplies available options much faster than the time available to evaluate them. The winner isn't the one who does more, but the one who correctly chooses what not to do.
