Portland cloud computing startup Stackery said Wednesday it has hired Puppet executive Tim Zonca as its new CEO.

Zonca takes over for co-founder Nathan Taggart, who resigned in June.

Stackery provides “serverless software” to help manage computer programs running in Amazon Web Services’ data centers. Its technology is designed to help clients make the most efficient and cost-effective use of AWS’ servers.

Zonca joined Portland-based Puppet five years ago as director of product marketing. He’s currently the vice president in charge of all marketing at Puppet – which, like Stackery, offers technology for managing computing inside data centers.

Before Puppet, Zonca had been a product marketing manager and director at two other Portland tech companies – Tripwire and Jive Software.

Stackery has 15 employees and has reported $7.5 million in funding.

Taggart, Stackery’s former CEO, said in an email this week that he’s taken the last two months off since leaving that company and is just now beginning to plan his next steps.
