About
TypeSafe is a close-knit team with a nerdy and prank-positive culture. We’ve hung out at Charli XCX, Justin Timberlake, Glass Animals, and Tiesto, destroyed each other in Killer Queen (an IRL arcade game) at the Emporium, suffered through Core40 and Barry’s Bootcamp, and eaten our way through every restaurant in Hayes Valley.
