He was reluctant to disclose details of the deal, however, Paull did say that "after two years of starting up something for someone else I want to try and do it for myself".
Paull, who will have an equity stake, has spent the past two years setting up Draft's regional operation, which now has 13 offices in nine countries.
The new agency would be based in Singapore because "that is where the greatest concentration of regional brands are, but ultimately I think Greater China is key to be successful", he added.
