About Me

Hi, I’m Mariya.

Startup CFO, advisor, and the person founders call when the numbers stop matching the story.

If you want numbers that open doors, growth plans that make sense, and a business story your whole team (and yes, even your mom) understands, we’ll get along great.

You should feel proud of the business you’re building, not just relieved it survived another quarter.
