Senior Product Manager · AI Product Manager · Barcelona

I build products that grow companies, from vision to shipped.

8+ years across B2B and B2C SaaS, turning operationally messy problems into shipped product and measurable outcomes. Most recently as an AI product manager, taking a multi-agent LLM platform into production in a high-liability regulated domain.

01 — What I work on

Product strategy & vision

Two-year visions, Jobs-to-Be-Done, competitive benchmarking, future press releases. Narratives that align engineering, sales and leadership on one direction.

AI & LLM product

LLM agent orchestration, RAG and retrieval design, prompt versioning, evaluation with golden datasets and LLM-as-judge, human-in-the-loop rollout. Production, not demos.

Pricing & packaging

Rate engines, licensing models and tier design. The Rentman licensing and pricing rework returned 40% revenue growth on its own.

Platform & operations

Turning fragmented operational knowledge — spreadsheets, inboxes, tribal expertise — into product infrastructure that scales without more headcount.

Discovery & research

100+ customer interviews, design sprints, dogfooding my own products. Deep research that changes roadmaps rather than decorating them.

Data-led execution

Analytics frameworks, success metrics and transparent roadmaps in Mixpanel and SQL. Every decision tied back to a business number.

06 — About

Eight years across two of the Netherlands' fastest-growing SaaS companies took me from product specialist to senior PM — B2B ERP at Rentman, then relocation software at Settly. Along the way I built the habit that still shapes the work: dogfood the product, talk to a hundred customers, and only then draw the roadmap.

Lately I've gone deep on AI product — multi-agent architectures, retrieval design, and the evaluation frameworks that decide whether any of it can be trusted in a regulated domain. It's the most interesting problem I've worked on. It is not the only thing I do.

I made most of the mistakes already — bad roadmaps, shipping the wrong thing, misreading enterprise needs. That's what makes the work interesting now.

“The metric first, then the mechanism, then the trade-off. Discovery before roadmap; evaluation before scale. Comfortable in the code enough to argue with engineering, never enough to do their job.”
