Fractional Product Lead · Growth · Barcelona

Fractional product leadership for teams that need growth strategy and senior execution without a full-time hire. I step into scaleups as a fractional product lead: PLG conversion, acquisition engines, AI-native product bets, and the experimentation practice that keeps them honest.

Taking 1 to 2 fractional engagements · 1 to 3 days per week · remote from Barcelona, working across EU and US timezones.

How I can help

Four areas I plug into, alone or combined, depending on where things are stuck.

PLG growth

Acquisition and conversion funnels built end to end: self-serve onboarding, pricing surfaces, lifecycle loops, and the experimentation cadence behind them.

Product launch, strategy & positioning

From opportunity to launch: strategy, narrative, and positioning that a whole company can repeat, including AI-native bets that actually ship.

Sales enablement & go-to-market

Arming Sales and Marketing with the story, pricing, and materials that convert, and closing the loop from GTM feedback back into roadmap.

Product mindset & coaching

Coaching PMs and teams on discovery, prioritisation, and craft, leaving behind an operating rhythm that runs without me.

What working together looks like

01
Intro call
30 minutes on where growth is stuck and what you have already tried. No deck required.
02
Two-week diagnostic
Funnel, data, and team review. You get a written read on the biggest levers, whether or not we continue.
03
Ship in the engine room
I work inside your rituals (standups, reviews, experiments) and own outcomes, not slideware.
04
Hand-off by design
Every engagement ends with documented playbooks and a team that can run them without me.
