Marcos Fernandez is a former founder turned VC at Fiat Ventures who co-founded Fiat Growth, a consultancy that has worked with over 200 companies, and he brings that hands-on growth and performance marketing experience directly into his investing by helping founders build and test acquisition channels rather than just providing board-level advice. He focuses on capital-efficient growth through scrappy experimentation and measurable unit economics, positioning uncertain markets as the best times to build while emphasizing long-term partnerships where he supports entrepreneurs across multiple companies throughout their careers.
