Note: Monzo is ranked under the name “Focus FS” so its hard to spot. Its also the only UK-based startup on this list. Awesome!
“In 2009, Businessweek asked Quid, then named YouNoodle, to pull together a list of 50 promising startups that were flying under the radar. Almost eight years later, it turns out that the list had its share of flops—companies that shut down or lost value—but some notable home runs as well. Cloudera, Palantir, Evernote, Twitch and Spotify all increased at least 30 times in value since 2009. If YouNoodle’s list had been a venture portfolio, it would have been one of the best-performing funds of the last two decades. So we asked Quid’s chief executive officer, Bob Goodson, to make a new list.”
