In Biarritz, the stage of the SHAKA Festival is not reserved for headliners. From September 24 to 26, 2026, the SHAKA Startup Challenge gives selected young startups a few minutes to convince, live, an audience where investors sit in the front row. For a founder, crypto or not, this might be the real reason to make the trip. Cointribune is a partner of the edition, with a discount code included.
