Chandler joins Karmarama after a year-long stint as an independent consultant, during which he worked with companies such as Virgin Airlines.
Prior to this, Chandler has worked with Karmarama chairman Jon Wilkins at Naked Communications where he was global business lead. Chandler is tasked with reinforcing the capabilities of Karmarama and Accenture Interactive in the data-driven content sector of the business.
Prestes was most recently innovation strategy director at Atomic London and has previously worked in Amsterdam and Brazil. He has had a career specialising in innovation, and brand and digital planning. He will be working on Karmarama clients, Clydesdale, Just Eat and Unibet.
Both Chandler and Prestes will report into Will Hodge, head of planning.
These two latest appointments will add to Karmarama's data expertise and will help keep it, "strategically ahead of the curve, enhancing Karmarama’s existing skill-set in digital, content and innovation," Wilkins said.
Since its acquisition by Accenture in November last year, Karmarama has been on a hiring spree. Most recently, it hired brothers Amardeep Singh Shakhon and Gurmit Singh Shakhon as its first executive experience directors.
Accenture Interactive meanwhile has expanded its presence in Europe with the recent acquisition of SinnerSchrader in Germany.
