Atlanta, GA — MacStadium, the industry-leading private Mac cloud provider enabling enterprise macOS workloads, announced the addition of Kenneth Tacelli as the company’s next President and Chief Executive Officer. Mr. Tacelli succeeds co-founder Gregory McGraw, who has transitioned to Executive Chair of the MacStadium Board of Directors. Mr. McGraw recently announced his retirement after a successful twelve-year tenure building and leading the company.

Mr. Tacelli has served in leadership roles at a number of technology-led companies and brings significant expertise in go-to-market strategies and operations to this new role. Most recently, he served as COO and Division President for Domino Data Labs, an enterprise MLOps platform company; Domino counts some of the world’s most advanced enterprises in its customer base, including over 20% of the Fortune 100. Previously, Tacelli held senior executive positions at several companies, including Alfresco, Datawatch Corporation, OpenText, CA Technologies and EMC, where he led key strategic, organizational and operational improvement initiatives and played a central role in executing several successful acquisitions.

“We are thrilled to welcome Ken to MacStadium and are confident that his extensive operating and leadership experience will help the company continue to meet and exceed the evolving needs of our client base and support our continued growth,” said McGraw.

“It is a tremendous honor to serve as MacStadium’s next CEO,” said Tacelli. “I am humbled by the support I have received from Greg and the entire board, and I look forward to building upon MacStadium’s unique position as the innovative leader simplifying Mac cloud solutions to the Apple ecosystem, collaborating with our global partners, and building our business with the help of our tremendous team.”

“On behalf of the Board of Directors, I want to welcome Ken to MacStadium and extend a sincere thank you to Greg for his exemplary leadership,” said Michael Medici, a Managing Director at Summit Partners and member of the MacStadium Board of Directors. “MacStadium has grown significantly in the last decade and solidified its position as a leader and trusted partner in the cloud-based Mac computing space. With the addition of Ken’s strong strategic, sales, and operational experience, we look forward to the company’s continued growth and development in the years to come.”

Leading global Fortune 1000 customers, including Box, Salesforce, CapitalOne, Delta, Thumbtack, and Pandora rely on MacStadium to build their critical mobile applications with its powerful next-generation virtualization platform, Orka 3.0. As Executive Chair, McGraw will work closely with Tacelli and the MacStadium leadership team to help ensure a smooth and successful transition.
