Lux Capital's portfolio companies sound like they ripped their product concepts from the pages of science fiction. Among these are self-driving car startup Zoox, a company gathering oceanographic data from fleets of autonomously operating boats called Saildrone, Desktop Metal whose 3-D printers that can make objects out of alloys on the spot, and 3Scan, a startup that makes detailed 3-D models of human tissue to help doctors better diagnose diseases, and several neuroscience startups including Kallyope, Halo Neuroscience and Cala Health. Today Lux Capital partners revealed that they have closed their fifth fund at $400 million to continue investing in the startups that are "inventing the future without destroying humanity." Lux Capital also announced that long-time venture investor, attorney (and karate black belt) Renata Quintini is also joining the firm as a partner. She previously worked at Felicis Ventures, was an investment manager for Stanford's endowment, and was an investor in Cruise Automation and Dollar Shave Club, among others.
