Amid the tech landscape, "unicorns" are few and far between. Last year, CB Insights tallied the odds of becoming a unicorn — a company valued at $1 billion or more — at under 1%. But already, within the first few months of 2018, a total of 16 companies have overcome those odds and crossed the billion-dollar-valuation mark. These companies, originally rounded up in a recent report by Pitchbook, are working to transform industries like transportation, medicine, entertainment, data analysis, and farming.
