Cottonwood Technology Fund is one of the world's top-10 best-performing VC funds according to Preqin, specializing in ultra-early hard science investments like photonics, advanced materials, and semiconductors that spin out of national labs and universities across Northern Europe and the U.S. Southwest. The fund positions itself as a bridge between these research-rich but under-served regions, with partners who act as hands-on commercialization experts helping transform lab technology into market-ready companies outside traditional tech hubs like Silicon Valley.
