Prezi was the first major investor in Elm (because they hired Evan) but definitely not the first major adopter. Source: back in 2015 I was personally in a meeting at Prezi's San Francisco office where Prezi employees were asking me (and two of my coworkers) about our experiences having adopted Elm at work, because they were considering doing so for the first time!
