SundaySky Bolsters Executive Team With Strategic Appointments

The enterprise video platform leader has made key leadership moves in 2025 in finance, revenue and marketing.

SundaySky, the premier AI-powered video platform for the enterprise, announced the appointment of four senior executives to further accelerate the company’s growth and leadership position in the video software space. The appointments include Tammy Martin as Chief Financial Officer (CFO), Mark Flaharty as Chief Commercial Officer (CCO), and Brendan Cournoyer as Vice President of Marketing, who have each joined the company in recent months. Dan Sylvester has also been named Chief Revenue Officer (CRO), stepping up from his previous role as SundaySky’s Sr. Vice President of Revenue.

These leadership additions continue to strengthen SundaySky’s executive team at a pivotal time as the company scales its video platform offering and deepens its investment in video personalization solutions for all the ways businesses grow.

“SundaySky is entering a period of strategic momentum, driven by innovation, customer success, and focused commercial execution,” said Marc Zionts, CEO of SundaySky. “Tammy, Mark, Brendan, and Dan bring the leadership, experience, and energy needed to execute with precision and accelerate growth across key verticals.

Executive Appointments Bring Deep SaaS and Enterprise Expertise

SundaySky continues to build the most seasoned and innovative executive roster in the enterprise video software space. The enhanced leadership team adds decades of proven success in driving growth, operational excellence, and customer value across high-performing software-as-a-service (SaaS) organizations.

Martin has also held CFO and leadership roles at companies including ABCYa and Lighthouse Computer Services, where she led multiple acquisitions and successfully executed exits to IBM, UnitedHealth Group, enChoice Technologies, and IXL Learning. Her expertise in SaaS metrics, operational discipline, and capital efficiency will be instrumental as SundaySky continues to expand its product and commercial footprint.
