About

I build marketing engines that outlast me.

I'm Maryna — a fractional CMO and growth partner with 15+ years building marketing functions for B2B SaaS, fashion, FMCG, and e-commerce brands. I've sat in the founder's chair, the agency chair, and the in-house CMO chair, and I bring all three perspectives to every engagement.

How I work

Honest before optimistic

I tell you what I actually see — not what's easy to hear. The diagnostic comes before the plan.

System before stunt

Great marketing is repeatable. I build operating systems and teams, not viral moments that fade.

Senior in the room

I sit on your leadership team and earn my seat. Strategy, hiring, and the hard calls included.
