Zixi has appointed Alyson Stewart, a former executive at AWS and Hydrolix, as its new Senior Director of Sales. In this role, Stewart will lead direct sales and partner go-to-market strategies to assist clients in transitioning live video workflows to IP-based delivery.
The appointment of Alyson Stewart signals Zixi’s aggressive pursuit of the legacy broadcast market as it attempts to replace aging satellite and C-band infrastructure with software-defined IP transport. By recruiting a key former AWS strategist, Zixi is positioning its platform to better integrate within cloud-native media supply chains where AWS and Hydrolix operate. This move reinforces the industry-wide shift toward hybrid-cloud live production and high-reliability IP contribution. Watch for Zixi to announce new managed service integrations or tiered licensing models aimed at enterprise broadcasters during IBC 2026 in September.
The hiring of Alyson Stewart follows a period of significant leadership and structural changes at Zixi. In October 2024, the company appointed Marc Aldrich—the former General Manager of AWS’s Media & Entertainment unit—as CEO, succeeding Gordon Brooks. This leadership shift was facilitated by the June 2024 acquisition of Zixi by Clearhaven Partners, a private equity firm that has focused on scaling the company’s market presence through expanded R&D and strategic personnel additions. Under Aldrich, Zixi has increasingly focused on ‘Satellite Replacement’ strategies, a trend driven by the continued squeeze of C-band spectrum available for broadcast.
Technological development has also accelerated alongside these personnel moves. In July 2026, Zixi announced a strategic integration with Comcast Technology Solutions (CTS) specifically to provide linear broadcasters with a migration path from C-band satellite to IP-based distribution. This partnership leverages Zixi’s protocol for secure, low-latency transport alongside Comcast’s Media360 management suite. Furthermore, during the NAB 2026 show in April, Zixi demonstrated new workflow automation tools within its ZEN Master control plane, aimed at managing complex live event stages. These moves collectively suggest Zixi is evolving from a transport protocol provider into a broader orchestration layer for the global video supply chain, per reporting from TVBEurope and SVGEurope in mid-2026.
