Investment managers Tiger Global and FTX Ventures led a $200m Series D funding round in Helium, a crypto startup, with participation from Khosla Ventures, GV, Multicoin Capital, Munich Re Ventures and FirstMark Capital. Helium is a decentralized network of over half a million hotspots that provides bandwidth for, and collects data from, nearby internet-of-things devices. Hotspot owners receive Helium tokens, called HNT, for their efforts. The more a hotspot is used, the more HNT an owner gets.
