Let's invest in women

We want to close the diversity and inclusion gap so that more VC capital goes towards female talent.

Let's invest in women

We aim to address gender bias in venture capital decisions and promote more diversity in the Swiss start-up scene. We do this by developing solutions & cooperations between (corporate) investors, entrepreneurship experts & facilitators and female founders. 

Why are we doing this?

Women are great entrepreneurs, who bring in even better investment returns than their male peers. So why is only 2.7% of the global VC capital going into exceptional female talent? We suggest closing the investment gap with the following four steps:

  • Getting more women lead ventures investment ready
  • Hiring more women into founder teams
  • Connecting them with interested investors
  • Improving investors outreach and processes
