"Lachlan is a self-starter who over the past four years has built up the Australian business of Zendesk, a company that has rapidly evolved from a Silicon Valley start-up to a major SaaS provider and recently enjoyed a very successful IPO," said Centrify senior director for APAC sales Niall King.
"We believe he brings the experience, the business networks and the motivation to grow strongly Centrify's business in Australia and New Zealand."
McKenzie joins Centrify from Zendesk where he started in 2011 as the company's first Australian salesman.
The appointment of McKenzie coincides with the move of Centrify's Australian head office from Brisbane to Melbourne. Some technical staff will remain in Queensland.
