Sarah Personette, most recently COO of Refinery29 and a former top marketing exec at Facebook, is joining Twitter as global head of client solutions.

Personette starts in mid-October and will be based in New York City. She reports to Twitter’s head of customers, Matt Derella, who previously was also global head of Twitter client solutions. In the role, Personette will oversee all of the global regional TCS leaders, client solutions development and global brands.

“Sarah has a career anchored in putting the customer at the core,” Derella wrote as part of a series of tweets announcing her hire. “She’s led global marketing and agency teams across publishing, tech and advertising. We are thrilled to bring her range of expertise and her leadership to Twitter and our partners.”

“I feel incredibly honored to be joining Twitter at this time and with this team,” Personette said in a statement. “Twitter creates the forum for people’s voices to be heard, and that is hugely meaningful for brands who want to make genuine connections. I look forward to working with the top marketers in the world to help them move consumers from inspiration to action.”

Since January 2018, Personette has been the chief operating officer of women-focused media company Refinery29, where she has overseen corporate strategy, business development, customer revenue, business marketing, growth and analytics, creative services, and research and insights.

Prior to R29, she served as VP of Facebook’s global business marketing team from 2014 to 2017. Personette also built and led Facebook’s global agency team. In addition, she was previously U.S. president of Universal McCann Worldwide and senior VP at Starcom Mediavest Group.

Personette also has served as a corporate director for Build-A-Bear Workshop since 2016; in addition, she is a director of Northwestern University’s alumnae board, She Runs It, and the Reisenbach Foundation. She holds a bachelor’s degree in political science and international relations from Northwestern.
