Nice overview of the unicorns, also some big ones missing...
Unicorns abound in fintech. Financial technology, or fintech, is a boom industry right now, with investment flooding into companies reinventing the way we do payments, lending, investing, and more. Valuations in the sector are also sky-rocketing as more money floods in. Many companies are now reaching the fabled "unicorn" status — the term in the tech industry for companies worth $1 billion (£640 million) or more. Earlier this year conference organiser Finovate pulled together a list of all the fintech unicorns in the world that have sprung up since 2000, the last big tech boom. We've pulled info on each of the companies, stripped out ones that have been acquired or lost value, and updated the values and money raised.
