At OVNI Capital (60m€ AUM), we back seed-stage startups in Europe tackling the hardest technical problems, often in critical industries. We’re operators at heart: every partner has built companies before. That entrepreneurial muscle is our edge in investing in these categories, where execution matters as much as science and engineering. We bring hard-earned founder intuition to help founders navigate the chaos—never becoming a source of noise or friction.
