About

Hi, I’m Antoni!

I’m 17 and I’ve always been driven by building things from scratch. What started as small technical projects quickly evolved into co-building startups within the B3L ecosystem, giving me hands-on experience in how technology drives business outcomes.


Until recently, I worked closely with early-stage founders, helping them shape everything from product and technology to operational structures and strategic vision. I thrive in environments where ideas are still raw managing cross-functional workflows, coordinating execution, and turning chaos into structured, scalable processes.


While building ventures from the ground up has been an incredible crash course in leadership and operations, I have made a strategic decision to step back from day-to-day execution. My absolute priority right now is my formal education and personal development.


I am building a strong analytical and financial foundation to pursue my long-term goal: a career in Technology Consulting. For me, technology is not just about writing code; it's about solving complex business challenges at scale.

Experience

Data Strategy &Solutions Consultant

Freelance

Apr 2025 – Present

Collaborated with stakeholders to identify operational bottlenecks and translated them into structured technical specifications and automated workflows.

Designed and implemented automated ETL pipelines that reduced manual reporting lead times by 98%, demonstrating a consulting-first approach to efficiency.

Leveraged a solid foundation in business intelligence and financial analytics to build scalable models that align technical performance with business KPIs.

I focus on understanding not just where to invest, but how value is actually built from the inside.

Julian Rubeńczyk

Founder &CEO of Zemen

Dec 2025

I am the first founder Antoni took on board and I am not only happy about it but also very proud. Working with him feels like cooperating with someone who truly understands how you think and at the same time has the knowledge to turn ideas into reality. If you need something, you get it. He understands the technical side deeply, but his real strength is helping you build the corporate and strategic side of your company.

I have been working with Antoni for half a year and it has been the most educational period of my life. If someone had told me that a 16 year old could run an entire holding company while actively supporting every startup he brought into the B3L ecosystem, I would not have believed it. Now I see it in action and it truly works.
