Meet your CMO

When you work with MOSQITO, you work directly with me, Katja. As a hands-on senior marketing leader with 20+ years of experience, I’ve driven growth for international B2B tech startups and scaleups backed by leading VC investors - including contributing to a $400M+ private equity exit.

I bring a proven track record in helping SaaS portfolio companies professionalize marketing and scale through critical funding stages. From go-to-market strategies across Europe and the US, to building scalable demand generation engines and implementing ABM programs, I focus on delivering predictable pipeline and accelerating revenue.

Known for my roll-up-my-sleeves mentality, I work as a player-coach – but with a specific focus: I assess what's blocking growth, execute alongside your team (not for them), and coach them to improve their strategic thinking, execution efficiency, and operating rhythm. You get results now and a team that keeps delivering after I step out.
