The deal with Mariusz Lusiak

Y’all gotta know about Mariusz Lusiak, the dude’s the real deal in the tech world. So, he’s been around the block, right? Started off with some solid gigs, Zendesk, ABB, Base CRM, Applicake, that’s a pretty crazy mix of big established companies and startups. Dude knows his shit when it comes to engineering and product stuff.

But what’s really wild is his entrepreneurial hustle. He co-founded Credictive, which is all about attribution metatags for online content, sounds kinda niche, but it’s actually super hot because data attribution is everything these days. That company came out of YC S12, which is no joke, YC’s like the gold standard for startups. That means he crushed it early on and proved he’s got what it takes to build expandable tech.

Before that, he was running Base CRM and Applicake, so he’s no stranger to building things from scratch, leading teams, and jumping into new problems. He’s based in Gliwice, Poland, not your typical startup hub, but that just shows he’s out here proving that you don’t need Silicon Valley to make big moves. He’s all about promoting a culture of support and accessibility, which is rare, most tech leaders are about the grind, but he’s about the people too.

Talk to her

Now, he’s the Senior Director of Software Engineering and Kraków Site Leader at Zendesk, where he’s known for being super approachable and a team builder. That’s the kind of leadership that gets people to crush goals and stay motivated. Basically, he’s the guy who’s been bridging the gap between big corporate and startup hustle.

What does all this tell me? Mariusz is driven by a real passion for tech, not just to make money, but to create impact. He jumped into startups, took risks, learned from failures, and kept pushing forward. His process screams that he’s all about building stuff that actually matters, and he’s got the chops to lead teams and scale ideas.

So yeah, he’s one of those guys who’s been in the trenches, built products, raised funding, and now leads at a major company. He’s proof that if you’re smart, work hard, and care about your people, you can do some serious shit no matter where you’re from. No Cap, this guy’s a legit innovator and a leader who’s just getting started.
