Managing Director
Nikolas Samios is a serial entrepreneur, long-time expert for startups and venture capital and early sustainability advocate.
He founded his first company around 25 years ago in parallel to doing A-Levels in Munich, Germany, and was quickly sucked into the grand new thing called „the Internet“, mainly helping traditional industries like print publishers, TV stations, retail chains and banks to digitise their businesses.
Around 15 years ago, he increasingly focused on the transactional aspects, financing, buying and selling startups. He set up a special family office for like-minded Internet entrepreneurs and venture capital investors that, for example, built up and managed the personal investment holdings of MP3 inventor Prof. Karlheinz Brandenburg and AOL Europe founder Jan Henric Buettner.
After many years, more than 100 venture capital transactions and co-authoring the German reference book on venture capital methodology DEALTERMS.VC, he co-founded PT1 – PropTech1 Ventures, one of the first PropTech/ConstructionTech venture capital funds in Europe and most likely the first ESG SFDR article 8 fund in this segment.
He was also appointed “Co-Chairman” of the PropTech platform of leading German real estate association ZIA as well as Deputy Chairman of the Young Digital Economy Advisory Board to German federal minister and Vice Chancellor Robert Habeck. Nikolas is part of the committees of multiple industry awards and events and was recently awarded “Head of the Year” by Immobilienmanager magazine.
In his rare spare time, he is producer and keyboardist of a VC band and supports multiple NGOs, including LFCA and many sustainability-oriented good causes.

Parallel to her work in financial management, organizational development, and general management, Anja studied part-time at the British OU University in Milton Keynes and received both a Master’s in International Finance and an MBA.
After many years of first-hand experience in corporate management, Anja increasingly specialized in supporting other founders and their shareholders in growth and turnaround situations and structured numerous financing rounds, mergers, and exits, often taking on interim CFO mandates. Together with Nikolas Samios, she also set up Brandenburg Ventures GmbH, the VC investment entity of MP3 inventor Prof. Karlheinz Brandenburg and advised numerous listed companies on corporate venture capital programs, portfolio, and M&A aspects.
