About Margarita

Do you have a product that needs to reach the next level: structuring, acceleration, pivot, scale, tech or data transformation?
I act as CPO / CPTO or Fractional CPO to **align product vision, organization, and business performance**.

With 14 years of experience in Product & Tech (startup, scale-up, regulated environments), I support leaders in structuring moments: rapid growth, technological overhaul, strategic repositioning, or team scaling.

  • Structuring of high-performing Product & Tech organizations
  • Implementation of clear governance (roadmap, OKRs, trade-offs)
  • Data-driven product performance management
  • Support for teams and leadership (VP, Head of, PM)

🛣️ My background:

With cross-functional experience ranging from engineering to Product & Tech leadership, I operate at the interface between strategy, technology, and business performance.
Strong experience in complex environments (insurance, medtech, B2B SaaS).

👉 Types of assignments:
  • Fractional CPO for a startup in the acceleration phase
  • Product & organization audit
  • Strategic definition and roadmap overhaul
