Run by Sandbox.
Sandbox's Acceleration Stage in Stuttgart accepts applications continuously and runs as a cohort closing with a Demo Day, with no duration published. Sandbox writes no cheque of its own and states no equity terms; its page points instead to third-party public grants for living costs in the pre-founding phase, including one earmarked for female founders. Sectors are media, SaaS and consumer.
