Marek Barlein, co-founder and CEO of Berlin Ventures, is an entrepreneur-driven investor who focuses exclusively on pre-seed and seed-stage technology startups in Europe and the U.S., with a primary emphasis on Germany. He invests his own money (not a traditional fund) in sectors like e-commerce, SaaS, fintech, AI, and energy, with ticket sizes typically ranging from €50,000 to €300,000, occasionally up to €500,000. His distinctive thesis centers on backing “outstanding teams with disruptive ideas” in large markets, offering hands-on operational support in strategy, internationalization, and marketing as a complementary partner. Notable portfolio companies include Scarosso (italian shoe fashion), Enmacc (OTC energy trading), Talon.One (business productivity), and exits like MyPhotobook, DeinDesign, and Teatox.
