21six

21six is an independent creative agency in London that works with global enterprise brands. It pairs insight and strategy with creative and digital work, and frames its goal as building movements rather than one-off campaigns.

What 21six offers

• Brand strategy — work on the business problem behind a marketing issue, such as growth, innovation or transformation.
• Creative — campaign and brand ideas built on a hard truth about the client's market or position.
• Digital — digital work that sits alongside the strategy and creative.
• Senior-led teams — small teams of experienced people with no account layers between agency and client.

Who it works with

The agency looks for large brands that want to make a difference and are willing to back bolder strategies instead of safe ones. It says it deliberately stays small so the people close to a problem have room to act.
