I’ve known Greg for over a decade as his client and as a business partner,” said Mark Zamuner, CEO of Two Nil Holdings. “Greg’s progressive and humanistic approach to management makes him a perfect cultural fit for our group. We share the same vision: a reinvention of how an ‘agency’ engages with clients and the marketplace that is made in the image of the entrepreneurs running the most disruptive DTC brands in the world.”
An award-winning marketing executive, Castronuovo is an Ad Age Media Maven with nearly 30 years of experience in marketing, media, and digital. He has worked at industry giants such as NBC, FOX, World Wrestling Entertainment, and Virgin Mobile. He was also SVP, Entertainment and Innovation for Initiative in New York. Throughout his career, Greg’s focus has always been about helping clients gain new perspectives to unlock greater returns.
As part of the acquisition, Castronuovo will join Two Nil Holdings as COO. In this position, Castronuovo will focus his attention on enhancing operational excellence across its operating assets (Juice Media, TWO NIL, and GlitchAi). He will also continue to incubate St@rt as a growth accelerator and seek out new investments and emerging technologies to add to Two Nil Holdings’s growing operations.
“Two Nil Holdings has a great foundation with a portfolio of amazing clients that continues to grow. I’m excited to help Mark and the team continue to build an ecosystem that is tailor-made for the modern day growth marketer,” stated Castronuovo. “My career has spanned various roles on the brand, publisher and agency side, and I believe it’s all culminated in our opportunity to take a fresh look at the ad agency model that meets the needs of the forward thinking brands we serve. I’m also excited to continue to build out St@rt as an innovation incubator within the Two Nil Holdings portfolio.
