   • Degree of innovation of the product / service 
   • Business model (e.g. sources of income, financial planning, market launch strategy)
   • Team criteria (entrepreneurial skills, relevant experience, motivation, culture fit)

We aim for gender parity among founders and create structures that also take into account the realities of life for female and non-binary founders. We actively encourage FLINTA* individuals to apply and give special consideration to people from the LGBTQIA+ and BIPOC communities as well as people with disabilities.

The customised, three-month accelerator is a hybrid programme, organised into sprints.

At the beginning of the programme, we conduct an individual skills assessment and needs analysis for each team using a business diagnostic sheet. Based on this, an individual development plan (roadmap) is drawn up with each team as plan for the accelerator programme and beyond.
