The firm has established a new branch to develop a range of licensed sugar confectionery products.
Richardson has joined Kinnerton after 14 years at Mr Lucky Bags to lead the new project, called The Great Character Candy Company.
The new division will offer a range of products targeted primarily at everyday sales, the first of which will launch before the end of the year.
Richardson said: "This is a fantastic project which brings together my skills in sugar confectionery with the Kinnerton team's strong presence and distribution in the market place.
"I am sure that together we will quickly establish significant sector innovation for our customers, so driving incremental sales for the group."
