Their contribution isn't just financial; it's about the broader perspective ROI brings. The way they connect the dots within

their network has been extremely beneficial for us."

Being a reliable partner who accompanies startup founders through their first or second investment round is my main motivation. With my experience as previous Managing Director of Austrian Angel Investors Association and roles in the venture capital scene I build a broad network, and as a result I am confidently capable of supporting startups in the best possible way.

Having started as an entrepreneur before moving to the investor side myself, my personal drive is to co-create new innovations and to help founders get to the next level. Besides start-ups, I am fascinated about real estate and crypto.

Don't swim with the current, address things straightforwardly - courtesy shouldn’t hold you back. As an entrepreneur, I realized that out-of-the box approaches are the best way to get things done, and that's the message I hope to pass on to other founders.

Be inspired by each other and grow together. Through good partnerships between investors and startups, competencies and contacts can be shared and multiplied. Progress and new perspectives fascinate me and I am absolutely convinced that this passion is essential as an angel investor.
