Join Anthropic in Berlin for the inaugural Claude Founder House — a full day built around the people turning frontier AI into real companies and real products. The day runs in two cohorts. From 9:00 am, the Founder cohort brings together founders and CEOs of the region's most promising startups for a structured morning of keynotes, fireside, and peer programming. From 2:00 pm, the Builder cohort opens the doors to technical luminaries and solo builders for a hands-on afternoon of building with Claude. Choose the cohort that fits you and apply below.
