Martin Sorrell-led S4 Capital has announced an M&A transaction — for Los Angeles-based TheoremOne —  to further bulk up capabilities at its Media.Monks unit. 

TheoremOne was founded in 2007 by Will Jessup (Founder & Head of Services) and has been led since 2017 by CEO Brady Brim-DeForest.  The company provides digital transformation services such as advising clients on developing and managing their digital products and resulting consumer experiences. 

Clients include American Express, AT&T, Intel, Starbucks, Caterpillar and others. 

Financial terms weren't disclosed but TheoremOne reported revenues of $58 million in 2021 and brings to S4 one additional “whopper” client which S4 defines as bringing $20 million annually in client fees to its coffers. TheoremOne will also add more than 5% to S4’s pretax earnings this year, the firm said.

TheoremOne’s Brim-DeForest stated: "We wanted a partner that could serve both as an accelerant for our growth and that was passionate about helping us disrupt the technology consulting ecosystem.”
