Yannick Rault: Why Usability Is Dead in the Age of AI

Yannick Rault built SheetGo from a construction site in Latin America into a platform used by over 5 million people, and he is now turning it into an AI back-office employee for the businesses that use it. In this episode Christian Sauer talks to Yannick about starting in construction, partnering with Google Sheets, raising less money as a European founder, and why usability might be dead now that AI can handle complexity better than a clean interface ever could. Yannick also shares what he looks for in founders he invests in, why go-to-market should come before the finished product, and how SheetGo now sells AI agents that work 24/7 to run the back office tasks customers used to automate by hand. If you want your own back office covered by AI agents built on five years of SheetGo's automation data, check out the virtual employees at 247team.ai.
