At Welltory, a profitable U.S. health tech startup, she has played a key role in the company’s growth to 11M+ users and $15M ARR, while building operational systems that support long-term scale.
Ksenia leads revenue, monetization, growth operations, and organizational design end-to-end — from financial planning and forecasting to team structure, OKRs, and executive alignment. Her work has directly contributed to over $25M in incremental revenue across multiple companies, delivering strong unit economics with up to 80% contribution margin and a Rule of 40 score of 89.
Known for bridging strategy and execution, Ksenia works closely with founders and boards to translate vision into operating reality. She has built and led teams of 200+ people, restructured organizations for scale, and resolved complex cross-functional bottlenecks across product, finance, technology, growth, and people functions.
Ksenia thrives in high-growth environments at the scaling inflection point — where clarity, speed, and operational maturity determine whether a company becomes durable or stalls.
