John Randles Leaves CEO Role at Bloomberg PolarLake to Join Start-up

Subscribe to our newsletter

John Randles has left the role of CEO at Bloomberg PolarLake and is on gardening leave until the end of September, after which he will become CEO of a technology start-up. Randles has been replaced by Warren Buckley, chief technology officer (CTO) at Bloomberg PolarLake and founder of PolarLake in 2002.

The switch took place last week, with Randles saying he enjoyed his time at Bloomberg, but is not yet free to name or describe the start-up he is moving to. Randles joined PolarLake as CEO in May 2006 and went on to work with the company for six years as it was transformed from being a provider of an industry agnostic enterprise service bus to a provider of a data management platform designed for the securities industry. Innovation, such as early adoption of semantic technology, supported the company’s acquisition by Bloomberg in 2012.

Buckley steps up to the post of CEO at Bloomberg PolarLake having founded PolarLake in 2002 and taken the role of CTO, a role he maintained after the Bloomberg acquisition of the company and that he is only now relinquishing. His early career includes three years as the founder and CTO of XIAM, a provider of wireless content targeting solutions that went on to be acquired by Qualcomm, and five years as a systems architect at Bank of Ireland Group Treasury.

Randles started his career with a seven-year stint at multi-channel banking specialist Eontec before it was acquired by Siebel Systems, where he became CTO of the company’s banking business.
