Svenja Lassen
Managing Director Germany
In addition, of promoting sustainable innovations in particular, one of Svenja’s biggest goals is informing more women about startup investments, getting them excited about this form of economic influence and lowering the inhibition threshold for entering startup investing. Also, because more female investors will increase the number of female founders and impact investments. For this reason, Svenja launched the Female Investors Network (FIN) at primeCROWD in 2020 and initiated the Mission #25to25 with the goal of 25% women in the startup-scene until 2025. Furthermore, she started to offer the FIN Academy in 2022 to share the basic knowledge for Female Business Angels to be.
