The role will see Jackson responsible for business growth through sales and marketing expertise, and he will provide advice around the products the agency offers to its clients.
Jackson was involved in establishing the 45-person Scandinavian company, which now spans offices in Stockholm, Gothenburg and Malmö, and counts Audi, Carlsberg and Volkswagen among its clients.
Janne Björge, president and founder of Nine Yards, said: "We’re in a really good place as an agency and we have an outstanding leadership team.
"With Kevin on board we have another likeminded leader to help us continue this growth and to keep on doing great things for our clients."
Jackson added: "I remember the first conversation I had with Janne about the future of brand experience; the result of that was Nine Yards.
"I'm delighted to be able to bring my thinking - and that of The Experience is the Marketing - to Nine Yards and create a unique proposition in the Scandinavian market."
Jackson launched his new agency, The Experience is the Marketing back in November, and also holds the title of sales director at Engage Works.
