Zixi Names Heather Mellish Vice President Of Global Sales

Zixi has appointed Heather Mellish as Vice President, Global Sales.

In the role, Mellish will steer Zixi's worldwide revenue strategy, overseeing new business acquisition, renewals and regional expansion across all customer segments. She will build, coach and scale a high-performing global sales organisation, introduce disciplined, repeatable sales processes and forecasting, and collaborate across functions to align go-to-market execution, strengthen enterprise relationships and maintain a robust global pipeline.

"Heather joins Zixi at a pivotal moment in our growth," said Marc Alrich, CEO of Zixi. "She brings a rare combination of deep domain expertise in cloud, edge, and media infrastructure, along with a proven ability to scale global sales and partner ecosystems. Her leadership will be instrumental as we continue to strengthen Zixi's position in the market. I'm thrilled to welcome her to the team."

Mellish brings more than 20 years' experience in sales leadership, partner ecosystems and go-to-market strategy across cloud and data infrastructure. Most recently, she served as Vice President of Partner Sales at Hydrolix, a fast-growing data observability company, where she established and expanded global partnerships with AWS, Akamai and other major cloud and distribution providers. Before that, during over six years at Amazon Web Services, she led worldwide go-to-market initiatives for Edge Services—including CloudFront, security and media—supporting some of AWS's largest customer sales efforts.

Earlier in her career, Mellish spent 17 years at Level 3/CenturyLink in sales, go-to-market and media distribution roles, building deep expertise in CDN, video transport and enterprise networking platforms.

"I've spent my career building teams, programs, and partnerships that deliver real customer value," said Mellish. "Zixi sits at the intersection of cloud, media, and mission-critical video delivery, and I'm excited to help scale the business globally. I'm grateful for the opportunity to join the Zixi team and contribute to the company’s next phase of growth."
