When Mark Read became CEO of WPP in 2018, succeeding Martin Sorrell, everyone knew he had a difficult task ahead of him.

The world's biggest ad holding company, which employs more than 130,000 people in over 100 countries and includes some of the best-known ad agencies like Ogilvy and media-buying network GroupM, has lost more than half its value since 2015 as people move away from traditional platforms like print and broadcast TV.

Read immediately began making dramatic changes, including merging agencies, closing offices, selling properties like research firm Kantar, cutting thousands of jobs, hiring a new leadership team, and pledging to hire 1,000 employees by 2021.

Business Insider spoke to current and former WPP executives to compile a definitive list of the 25 most powerful players helping Read turn the industry's biggest network around. The list includes the CEOs of WPP's biggest agencies along with rising stars like:

• Chief client officer Lindsay Pattison, who insiders say is reshaping account teams and working to shake up WPP's dusty image.
• Chief people officer Jaqui Canney, who led HR at Walmart while the retailer adjusted to the rise of Amazon and now oversees WPP's attempts to hire, train, and retain more tech-savvy talent around the world.
• Head of strategic development and partnerships Sanja Partalo, who manages WPP's relationships with platforms like Twitter, Adobe, and Salesforce as well as its multi-million-dollar Google Cloud business.
• Digital agency Essence global CEO Kyoko Matsushita, a former marketer for Sony and Electronic Arts who helped make Asia Pacific Essence's fastest-growing region before stepping up to lead WPP's largest network, GroupM.
