Maria Baumgartner

Advisory Board

Maria’s diverse and successful professional history has one common denominator: a desire to truly get to know people. This curiosity has driven Maria from her early days as a startup founder and young political activist up until today as general manager of Speedinvest Heroes.

“The moment when you connect with another person and challenge him/her towards a new set of possibilities is what I love the most!”, says Maria.

This social skill set, practiced over many years in various leadership positions and professional training (such as a Master degree in Mediation) is a crucial asset for Speedinvest Heroes. Building out our network of talents and then quickly matching the potential of a given candidate with the right opportunity in our portfolio, is where Maria excels like no one else.

Maria’s personal working history starts 1992 in the early internet area. As the GM of one of the first big success stories coming out of Austria (Datenwerk/Blue-C), she saw her company grow to an agency group with more than 200 employees across Europe, including an IPO at the “Neue Markt”. Having sold her stake early enough before the bust, Maria continued her entrepreneurial path that included managing a research think tank on Artificial Intelligence (long before the hype), spending time in Silicon Valley and, eventually, helping to found Speedinvest as the first business angel fund in Austria.

For Maria, having gone through many diverse roles and businesses, this approach comes natural, as does her positive attitude towards people in general.
