American software company Domo didn't drop a surprise smash album in 2015, but it did come out with a surprise data software and a $2 billion valuation. Founded by Omniture cofounder Josh James, Domo aggregates data from more than 300 sources and puts it in a one-stop location with real-time updates and practical data visualization--that way, businesses can get a holistic view of how things are running, from social media following to sales numbers. Though it wasn't open to the public, Domo has been around for five years, operating in relative secrecy, collecting more than a thousand clients who each pay a minimum of $25,000 to gain access to the Domo dashboard. This helped Domo get way ahead of any competition and rake in $100 million in sales in 2015, with James expecting that number to double this year. Not bad for a company that only just made its software available to the public.
