Studio events
Future Proof ideathon for students

Identify a problem – offer as a solution – create a business plan – pitch! Your business idea will be evaluated based on a number of factors by a panel of in-house experts. A positive feedback will be followed by a private interview and then the registration of you as a founder of your own startup. During this period, the Startup Studio team members will support you as mentors.

The STARTUP CAFÉ conducts one-on-one consultations regarding businesses in the peer-to-peer platform market. Excellent business ideas, especially in the social and sharing economy fields will be funded on the spot with an initial 2 million investment and offered a further wide range of support from Gaiax Startup Studio.</sp an>
