Castles’ New Castle, As Puopolo Steps Down


A media tech company focused on monitoring and workflow products is making a change at the top, giving its keys to Castles.

That would be Dan Castles, who is one of the founders of Telestream and is returning to the California-based company as CEO.

The change is precipitated by the departure as Chief Executive of Scott Puopolo, who has led Telestream since 2017.

Eli Weiss, Managing Director of Telestream’s majority shareholder, Genstar Capital, said the company was “grateful” for Puopolo’s many contributions to the company.

“As we embark on a new decade which promises to bring fundamental changes to the broadcast industry, we are excited to have Dan rejoin Telestream to help drive its growth strategy and continue to lead the industry,” Weiss said.

Under Castles’ 20-year leadership, Telestream built a global reputation for products in the realm of transcoding, quality assurance, and workflow solutions.

Castles commented on his departure, saying “Broadcast business models need to evolve to meet rapidly changing consumption habits. Telestream is perfectly positioned to help organizations navigate the myriad challenges that face them. Our employees’ dedication to excellence, spirit of innovation and unwavering focus on customer needs are at the heart of our success and the reasons why I am excited to come back and help take the company into its next stage of growth and evolution.”
