Growth marketing for ecommerce
& service firms.
Your campaigns are only as good as the data you feed them. Stop guessing. I design the infrastructure that lets the algorithms finally see what they are doing, and the whole business can grow without burning budget.

I mainly help online stores, as well as service firms and SaaS companies, grow and build a competitive advantage through marketing built on data and technology.
You don't have to take my word for it
“It is genuinely hard for me to find words that capture how highly I rate this collaboration. Mateusz is a specialist whose standard of work goes far beyond what we are used to in Poland for this type of service.”
Dominik Łyżwa, Doktor Monika
“For years we had problems with data analytics in our online store. Different specialists, different plugins, code, methods… Mateusz rebuilt our entire analytics from scratch, put everything in order, and it finally works the way it should!”

Problem, solution, result
Marketing built up over years without a coherent plan.
A developer looks after the website, an agency runs the campaigns, and new plugins get added with every fix. Nobody is responsible for whether the whole thing works.
- Data:Several plugins send the same events. Sales are counted twice and Meta cannot match buyers to ads.
- Ads:Account changes are made on intuition, because flawed measurement makes it impossible to judge their effect.
- Automation:Data is moved between tools by hand, so some information gets lost or arrives late.
Approach based on understanding the technology.
I understand how ad platforms learn from the signals they receive, and I design both the account structure and the data flow around those mechanisms.
- Data:Events come from one clean configuration, and Server-Side Tagging completes and enriches the data sent to ad platforms.
- Ads:Every account change has a defined goal and review date, and its effect shows up in reliable data.
- Automation:Automations take over repetitive tasks, and tools exchange data without your team's involvement.
Steady growth on proven foundations.
Marketing stops being a series of random attempts. Every decision has a reason, and each next step builds on what has already worked.
- Data:Algorithms learn from complete data, and reports show which activities drive results.
- Ads:The ad account grows steadily, and budget decisions rely on trustworthy data.
- Automation:Information arrives on time and intact, and your team focuses on what it does best.
No more guessing.Time for a system that delivers.
Replace marketing chaos with architecture that runs on hard data.
