The increase in gross margins was put down to a focus on higher value-added services and efficiencies across the group's operations and design teams.
The financial year, ending 31 December 2011, saw an increase in headcount and investment in both Motivaction's service offering and in technology.
Its total assets less liabilities and shareholders' funds increased by 21%, whilst net current assets increased by 30%.
Areas of growth for Motivaction were within brand experiences and experiential marketing as well as incentives, awards and celebratory events.
TNT, McDonald’s, Renault Trucks, Lebara, Gore and PWC are among the clients cited as helping boost Motivaction.
Motivaction managing director David Buxton said: "We plan to continue to delight our corporate clients, make the business a great place to work and to increase our levels of profitability.
"We are proud of Motivaction’s investment in our people. Our staff turnover was less than 10%, and we created 10 new roles across the business during 2011. In fact, we are still increasing our business development and project management teams, to ensure that the strong execution and creativity with which Motivaction is accredited will always be apparent to our clients."
