The Premier League outfit, who joined forces with Sauber in April, are due to reveal the new partner in eight weeks' time.
"The first commercial joint venture will be announced in two months' time," Gourlay said at the International Football Arena in Zurich.
"You are going to see some results of the partnership very soon. We both want to be winners in our field and have the same values. Through our relationship with Sauber, we can go into 19 different markets in one season."
Gourlay refused to name the new backer.
