Achieving goals by working together

Our recipe for success for start-ups and grown-ups

Access start-ups directly. Access established companies directly. Jointly develop new solutions and business models. Tap into new markets. Increase your speed and efficiency. These are the goals of our A² programme. WISTA Management GmbH organises the whole A² programme from A to Z, while our start-ups and industrial partners focus on their business. Just the way it should be.

Why choose us?

  • Because we have more than 20 years’ worth of experience of working with start-ups and have an extensive network.
  • Because we have very good contacts to established companies.
  • Because we have successfully organised several accelerator programmes.
  • Because we are 100% neutral as a 100% subsidiary of the State of Berlin.
  • Because we focus on maintaining the balance between start-ups and established companies.

A² Programme: Smart City

Participants of the A² programme will deal with all the critical issues specific to their product, their company, and their respective industry in thematic sessions. The programme strikes a careful balance between theory, practice and networking, ensuring that there is enough time to take care of everyday business. The programme aims at enabling participants to apply the learned know-how to their own product, or service, and to improve it continuously in cooperation with their mentors and industrial partners.
