Head of Product and DesignSpeakerAuthorDesigning products since 2008
You've shipped, people are using it (or soon will), and you can feel the experience could be better. But when you build every day, you know each screen by heart, and it gets hard to see it the way a new user does.
Maybe you have a designer, maybe you don't. Either way, an outside pair of eyes that thinks about design and business catches what your team can't see anymore.
You don't need a 60-page audit or a €40k redesign. You need someone who has led design and product to look at your flow, and an honest list of what to fix first.
Founders usually book when
Tell me about your product, your team and the flow you want reviewed. Or have a quick chat first.
A test account, a staging link, a TestFlight / Google Play build or a Figma prototype. About 10 minutes.
Report and video within 5 business days, plus one round of follow-up questions.

I've been designing digital products since 2008, in startups, mid-sized companies and big organizations, so I know how small product teams work: fast, stretched, and usually without a designer for every problem. Today I'm Head of Product and Design at NFON, where my team builds AI products like chatbots and voice assistants.
You work directly with me: no agency, no junior designer, no checklist tool. Born in Argentina, based in Munich, dad of two. I review in English or Spanish.

Book a founding spotAdd-ons: extra flow in the same product, €250 · live 45-min debrief with your team, €150
For business clients. Paid upfront, no VAT added. Full refund until I start your review. Once it has started, it's non-refundable.
One journey with a clear start and end, like signup, onboarding, checkout or a core task. That includes the path from your homepage into the product, from the first click to the first win. Up to about 15 screens.
If it's the way into your product, yes, that counts as a flow. If it's a pure marketing site, just ask, and I'll tell you honestly whether I'm the right person for it.
Yes! A clickable prototype (Figma or vibecoded) works great, and it's the cheapest moment to fix things: before you or your team develops it further.
Yes. The review looks at your flow the way a first-time user experiences it, so it doesn't need your data. For each of your top 5 fixes, I'll also tell you what to track, so it's ready once you set analytics up.
Sure! As long as there's something to click through: a live product, a staging build or a prototype. If it's still just an idea, it's too early, and I'd rather tell you that than take your money.
Same review, same care. The founding spot is €100 less because I can show your name, a quote and a short summary of the findings on my site. If your product or flow is confidential, book the regular review.
That's outside this review. I make the recommendations concrete enough for your team, or a designer you work with, to take it from there.
Of course! Grab a free 15-minute slot, or email me your product link and questions.
¡Sí, claro! Same price and same turnaround.
3 founding spots at €350, or a regular review at €450, any time.
