Squarespace's David Lee has turned the tech start-up's creative team into one of the world's most renowned in-house units in the world since he joined from TBWA Worldwide in 2013 as chief creative officer.

Yet when speaking on the Mumbrellacast, he says that he doesn't believe in-housing creative is the path most brands should be taking.

Later in the conversation, Lee also speaks about his observations from judging at this year's Cannes Lions, the stress of creating a Super Bowl ad, a shifting focus to international marketing and how the product inspires the creative for Squarespace's work.
