The role was previously held by Matt O'Brien, who was made managing director of the agency last year.
Groves will head the account teams working across the agency's clients, which include Budget Car Rental, Holiday Cottage Group, AXA, BUPA and PDSA.
Joining from full service agency Digivate, Groves brings 10 years of online marketing experience to the role.
O'Brien said: "After what was a great year with some solid client wins, bringing Mike on board now is key to managing that growth to ensure that we're able to continue delivering the very best service for our clients."
