iStrategyLabs founder and CEO Peter Corbett announced Tuesday that the Shaw-based company has been acquired by J. Walter Thompson — a part of communications conglomerate WPP.

“Some founders think that the day you sell your company is ‘the end’; that you’ve sold your baby,” Corbett wrote in a post on the ISL website. “I never set out to do that — so for years I resisted all the offers that came our way, of which there were many.”

However, the post goes on to say, there came a time when he realized that his nine-year-old, nearly 90-person advertising agency was no longer a small company, and needed the space and opportunity to grow further.
