Product & Growth Based in Europe

I design product moves that compound.

I’m Katarzyna Biel — I help teams turn ambiguous problems into focused experiments, clear narratives and measurable growth.

  • 0 → 1 product discovery
  • Experimentation & growth loops
  • Strategic storytelling

Selected work

A few examples of problems I like to solve.

Product strategy

Reframing a roadmap around outcomes

Partnered with leadership to replace a feature-based roadmap with outcome themes and simple metrics, creating clarity for product, design and go-to-market teams.

Experimentation

Designing a lightweight growth loop

Mapped the activation funnel, identified one high-impact moment and shipped a small set of experiments that improved trial-to-pay conversion.

Communication

Telling the product story simply

Helped a team rewrite their product narrative into a short, visual deck that aligned sales, product and marketing around the same message.

What I’m good at

A mix of product thinking, operations and narrative.

Product & discovery

  • Clarifying problems and shaping bets
  • Mapping journeys and identifying leverage points
  • Working closely with design and engineering

Growth & experiments

  • Defining simple metrics and guardrails
  • Designing experiments that actually ship
  • Connecting product work to revenue stories

Story & alignment

  • Turning insights into crisp narratives
  • Building decks that teams want to use
  • Facilitating conversations, not just sending docs
