High50 has appointed Andy Williams as operations director.
Williams was formerly audience director at Yahoo! UK and IE.
The appointment follows that of Stefano Hatfield as editor-in-chief, who previously worked as editor-in-chief of London Live.
Williams says of the move: "It is very exciting to join a business with this much potential for growth so early on and when it is moving so fast. Without some of the legacy issues other businesses face, we're building a very innovative and disruptive business. We have better insight into our readers, closer relationships with our audience and massive potential to scale up our business globally."
