They will join TRBR in October. The pair are expected to work across the agency's portfolio of clients, which include Tesco, Heineken and Sky Networks.
The signing reunites the pair with Justin Tindall, TRBR's creative partner, with whom they worked at DDB London. Tindall was formerly DDB's head of art.
During their time at DDB, the duo also worked on several high-profile campaigns for clients including The Guardian, the Financial Times and Volkswagen. It included VW's "incredible but true" campaign that was awarded two silvers and a bronze at this year's British Television Advertising Awards.
Tindall said: "Matt and Pete are exceptional talent. I am delighted they are joining us."
The appointments come 12 months after TRBR's founder, Paul Hammersley, raided his former agency DDB London to poach both Tindall and Karen Fisher, who was the agency's then head of account management.
