The move to Spank reunites Venville with its founding partner and director Karen Cunningham, who produced Venville's first commercial.
Venville, whose reel includes ads for Nike, Xbox, Toyota and Honda, as well as the 2007 "gun crime" ad for Choice FM through Abbott Mead Vickers BBDO, has also directed a number of films such as 44 Inch Chest, which stars Ray Winstone and John Hurt, and opens in the UK on 22 January.
Venville founded Therapy Films 15 years ago alongside Daniel Todd. He joins Cunningham, Steve Bendelack, Michael Geoghegan, Tim Brown, FAQ and Pat Holden on Spank's roster.
Venville said: "After all these years, working in London is as important as ever because commercials here in the UK are still rooted in the idea."
His arrival coincides with that of Bash Robertson, who rejoins the production company as a managing partner.
Robertson initially set up Pink, which later relaunched as Spank, alongside Cunningham in 1996.
The company ditched the Pink brand in 2008 when Cunningham teamed up with the former Red Bee Media producer John Golley to create Spank Corporation.
