Our Team

Graeme Warring
Chief Executive Officer

Young gamers, as well as worrisome parents, will have to thank Graeme Warring for creating new virtual worlds that are kid-friendly, educational, and absolutely fun-filled.

From collectible toys like die-cast aircraft models, camping-inspired gears and action figures, and those cute Sqwish pencil toppers, Graeme has created virtual worlds that extended children’s real world playtime experience and vice-versa, while connecting them with other children from and outside of America.

His innovative business model that gave birth to major game titles – ActionJetz, Camp Treehouse, and recently Sqwishland – has definitely changed the landscape of game development , especially for young online gamers. Amidst the aggressive competition in gaming development and technology, Graeme found a niche.

From online games; Graeme ventured onto global resourcing since the financial aspects of different corporations started to plummet. He found a hybrid business model that will meet the different needs of companies with a reasonable cost. To date, Extension Corporation continues to expand as the need is being recognized in the intercontinental market.
