Role Swapping at Xenomorph

Subscribe to our newsletter

Greg Johnson has risen to become chief executive officer of data and decision support platform provider Xenomorph. The company’s former CEO and co-founder Brian Sentance has taken on the marketing role.

The role swapping was decided by the four founders, who have majority ownership of the company and all of whom, says Sentance, “Look to do our best to increase the value of what we own”. As such, Sentance is now taking on more of an ‘evangelist’ role for the company while Johnson will take on the leadership role involving negotiating and operational management in addition to his previous responsibilities for sales. Another co-founder Matthew Skinner is contributing to the financial control role.
Johnson joined the company a couple of years ago as sales and marketing director, and was then promoted to chief operating officer last year. The COO role no longer exists.
