Daye, a “femcare” startup developing a new type of tampon that uses CBD to help tackle dysmenorrhea, has quietly raised $5.5 million in funding from high-profile investors in the U.S. and Europe, TechCrunch has learned. Backing the seed round is Silicon Valley’s Khosla Ventures, along with London’s Index Ventures and Kindred Capital. The investment sees Khosla’s chief of staff Kristina Simmons, Khosla venture partner Tim Westergren (who also founded Pandora), and Hannah Seal, principle at Index, join Daye’s board.
