Data collaboration platform InfoSum has promoted Lauren Wetzel into the role of CEO.

Wetzel, who previously held the position of Chief Operating Officer, takes over the reins from Brian Lesser, who has led the company as Chairman and CEO since 2020.

Prior to joining InfoSum in 2020, Wetzel held senior strategy and operations roles at AT&T, Xandr, and Deloitte. Lesser will remain an advisor during a transition period, with his new role to be announced in the coming weeks.

"Lauren is a pioneer in the data collaboration industry, having been involved with data clean rooms before the term even existed. She has run day-to-day operations at InfoSum for years as COO and as a board member. I'm thrilled to watch her continued growth as the new CEO of the company after many years under the mentorship of Brian Lesser," said Board Director at InfoSum and Partner at Upfront Ventures, Mark Suster.

"I’ve had the privilege of leading InfoSum’s operations as it’s grown exponentially since 2020. As I transition into this new role, I am excited to build on InfoSum’s position as the global leader in data collaboration. We will continue to deliver innovative solutions that empower customer-centric businesses to execute data-driven advertising that resonates with consumers while prioritising their privacy," said Wetzel.
