Senior director Matthew White has left creative agency Smithereen to launch his own branding and design company.

The split will allow White to inaugurate Supergrizzly, a joint venture with Wapping-based television and corporate production and services company SO Productions.

As the creative arm of SO, White will provide brand and channel identities, promos, titles and interstitials work for broadcasters and producers, as well as advertising and creative marketing work.

“We had a few creative differences and I felt I needed to steer a company rather than just work for someone else,” said White.

“Supergrizzly’s strength will be its ability to exploit an idea regardless of whether it has a big budget or is just shot on a DV camera.”

White’s previous experience includes stints as a post-production and effects producer at Cell Animation and MPC.

Recent design credits include work for Disney, Discovery, Five and MTV.
