Before becoming a Partner at Eleven Ventures, Martin Ouzounov served as the firm's COO and held CFO/COO roles at companies like space company EnduroSat, and he's managed M&A deals worth more than EUR 250 million, giving him a hands-on, numbers-focused approach that shows up in his writing on cash-flow planning and fund structures. His mixed background in business and software engineering also comes through in how he talks about portfolio companies—for example, he highlighted Payhawk's growth to $100M ARR by focusing on burn multiple and cash efficiency rather than just growth alone.
