Monzo CFO Alwyn Jones is leaving the challenger bank for cryptocurrency company Luno after less than three years, City A.M. reported. He is the latest in a string of departures from Monzo. In January, founder Tom Blomfield stepped down, citing mental health issues. Monzo head of marketing Tristan Thomas and chief risk officer Lisa Nowell both left last year. Jones will take on the role of CFO at Luno, which raised VC funding from backers including Balderton Capital and Venturra Capital before it was acquired by Digital Currency Group last year.
