San Diego-headquartered Big Day, the startup agency founded by ex-Wunderman Thompson veterans during the height of the pandemic, has added cybersecurity company Tenable to its client roster. The agency will handle campaign and branding work for the firm. 

Tenable, listed on NASDAQ and founded in 2002, was searching for a creative partner to bring a fresh perspective to their brand, the company said.  

Big Day made its official launch announcement last September and was formed by former Wunderman Thompson executives Peter Sayn-Wittgenstein and Kristie Brown, along with branding specialist Ahab Nimry.  

Tenable joins a Big Day client roster that includes Casper, YMCA, HexClad, Royal Caribbean Group and BNP Paribas Open are clients.
