Sylwia KacprzakHi, I’m Sylwia. Marketing and paid media leader, 13 years at Microsoft, open to Head of Marketing, Marketing Director and Marketing Lead roles in sport, health tech and tech.

Marketing that moves people. And the numbers.

I help brands grow revenue from every pound they spend. For 13 years I led marketing at Microsoft: Xbox, Windows, Surface, Microsoft 365 and most recently Copilot, across Europe and the UK on budgets up to $120M+, beating the incrementality benchmark by 14% with a super lean team. Before Microsoft, sport: Wimbledon, Euroleague and the BBL.

In the arena

Sport is where I started. It’s still where I work.

From the Idea Prokom Open, where Rafael Nadal won his first ATP title, to a Euroleague club that reached the Elite 8, then Wimbledon and the BBL, sport is where I learned to run a live event under pressure. Today I still do it every season, as a Euroleague delegate.

A little about me

I market sport, and I play it too.

I’m Sylwia, a Pole who came to the UK alone at 19 and built my career in my second language. An identical twin and a competitor at heart. Sport came first, from Wimbledon to Euroleague basketball, and it still shapes how I lead: prepare hard, stay calm under pressure, and win as a team.

Since then I’ve spent 13 years at Microsoft across Xbox, Surface, Windows and Microsoft 365, running budgets from $30K tests to $120M+ launches. What drives me hasn’t changed: more growth from every pound, less waste, and new ways to win.

Off the clock, I play basketball (since I was six), tennis and padel. I’m also a certified holistic health coach and nutrition coach, which is why I find health tech super interesting. I’m always up for a good conversation, or a game.

Marketing strategyGrowth marketingPaid mediaExperiential & OOHRetail mediaSports marketingTeam & agency leadership
Why health techFrom tech to health tech, it’s the same job.

Health tech sells subscriptions, builds trust and has to prove what works. That’s what I’ve done again and again over 13 years, with Microsoft 365, Game Pass and Copilot. With two health coaching certifications and a postgraduate diploma in business psychology, I understand the health customer, and what makes them stay. The real difference is the rules on health claims: what you can and can’t say on your website and product pages, and in your ads on Google and Meta, under UK advertising standards. I know where those lines are, and how to market well within them.

How I approach the work

Turn big plans into proof.

01 / UNDERSTAND

Ask the better question.

Get clear on the audience, the business goal and what success looks like, then bring legal, privacy and finance in early.

02 / ACTIVATE

Make the moment matter.

Align global, regional and local teams, agencies and partners around one plan, one rhythm and one story, and show up where people already are.

03 / LEARN

Follow the evidence.

One measurement framework, every channel accountable. Challenge partners for value, keep what works, and test the next idea.
