As an author, I wanted my universe to be respected, not just replicated. Martin understood this challenge immediately. Beyond his attentive listening and ability to rephrase my needs, he proposed solutions I hadn't thought of. I particularly appreciated his great responsiveness. Communication was fluid, without any gray areas, with meticulous work from start to finish. A very good professional encounter that I highly recommend.

I've learned to distinguish between doers and true partners. Martin falls into the latter category. What I expected: a simple technical audit. What I received: a structured analysis that speaks to both technical/product teams and marketing teams. Each point raised is contextualized by business impact. We're not talking about abstract problems, but missed opportunities, costly user friction, decisions to be made in a specific order to maximize impact. The deliverable is immediately actionable. No need to re-translate it, no need to re-interpret it. We know what to do, in what order, and with what priority. What convinced me from the start: Martin asks the right questions before starting. He seeks to understand the challenges, not just tick boxes. For a leader who wants clarity and measurable ROI on their tech investments, this is exactly the profile you need. I recommend Martin without reservation.
