Gemini Trust, the cryptocurrency exchange founded by the Winklevoss twins, just hired Julian Sawyer, co-founder and COO of UK neobank Starling Bank. Sawyer will run Gemini's European operations. Gemini was founded in 2014. Similar to Coinbase, it offers users a platform to buy and sell cryptocurrencies like Bitcoin. Starling was also founded in 2014, but its younger competitors have outpaced it in customer acquisition. Gemini's goal is to build the future of money. Leaning on space travel imagery, they call themselves a "galaxy-changing team", and employees the "astronauts."
