S4 Capital chief Martin Sorrell has acquired Los Angeles ad tech company TheoremOne as the WPP founder returns to the acquisition trail in the aftermath of his firm's accounting snafu.
TheorumOne advises clients on product strategy, engineering, design and culture, then partners with them to build and launch technology-driven solutions to their most complex problems.
It was launched in 2007 by Will Jessup and has been led since 2017 by Brady Brim-DeForest.
The company has more than 370 staffers and clients such as American Express, AT&T, Intel, Starbucks and Caterpillar. North America accounts for 70 percent of its business.
TheoremOne will operate autonomously and its leadership team will remain in place.
The combination with S4 Capital provides TheoremOne access to new capabilities including those in the media, content, data and analytics verticals.
Sorrell said S4 Capital is "building a genuinely integrated offer for our clients comprising best-in-class technology services combined with content and data & digital media expertise."
He said the vision and ambition of Theorem's team "will no doubt be a great fit for us."
