About Luis

Do you have a product that isn't taking off, a saturated roadmap, or lagging retention? That's where I come in.
I help startups and product teams turn ideas and data into products that users adopt, repeat, and recommend. My focus is on deciding well and quickly: customer discovery to validate before building, experimentation to reduce risk, and honest prioritization that aligns business, engineering, and design behind what truly generates impact.
What sets me apart? I've managed B2B SaaS products in demanding environments - fleet electrification at tb.lx (Daimler Truck), experimentation and A/B testing at Prima, and Mango's loyalty program - all in environments where aligning people and stakeholders behind a product vision was a challenge!
I work equally in Portuguese, Spanish, and English, so I'm comfortable in multi-market projects.
Projects and deliverables I typically manage:

Product strategy and roadmap, both 0→1 and scaling
Customer discovery and research (interviews, validation, product-market fit)
Experimentation and A/B testing programs
Retention, loyalty, and activation initiatives
PRDs, OKR definition, and prioritization
Alignment of multidisciplinary teams (product, engineering, design, and data)
