I’ve always been a builder. My first app — built at university for an aerospace company — taught me something important: I would rather make things than write about them. Then I spent seven years at PwC, but not on the path people usually imagine. Across seven departments and two regions — Paris and DACH — I worked on large-scale mergers, capital markets operations, and high-end advisory for major US and European clients. I kept moving toward the most complex, highest-stakes work I could find: company-defining transactions where the analysis had to withstand real scrutiny. Seven years, seven departments, two countries — because I wanted range, and I wanted depth. Across all of it, I saw the same pattern. Brilliant professionals were spending too much of their time on repetitive, low-leverage work — and too little on what actually makes them valuable: judgment, expertise, and trust. From the inside, I pushed digitalization initiatives and trained hundreds of professionals on data tools. The opportunity became obvious. But it didn’t need another slide deck, workshop, or internal initiative. It needed a real product. So I went back to building. I launched Moby, recruited my best friend as CTO, got into Y Combinator, and now work with some of the largest audit networks in Europe — including BDO, Baker Tilly, PwC, and many others. I’m not an engineer. I’m a builder. AI has given people like me a new kind of leverage: the ability to combine breadth and depth in a way that wasn’t possible before. To architect company-scale systems while staying close to the domain, the customer, and the real operational pain. At Moby, that’s how our agentic system was built — not as a collection of features, but as infrastructure that has to hold up under real audit work, on real client data, with a strong verification layer. For the profession, my conviction is simple: professionals won’t win by working more. They’ll win by being amplified. By spending less time grinding through repetitive tasks, and more time on the judgment, expertise, and trust that actually distinguish them. At Moby, we meet professionals where they already work — in Excel, in documents, in their existing flow. We stay in the background, remove friction, structure complexity, and unlock a new way of working. That’s the future we are building.
