Our story
Turning big ideas into lasting behaviour change
Launched in 2020, we’re a growing agency on a mission to improve health and wellbeing.
Our founders started Twelve driven by a shared desire to do great work that genuinely makes a difference. As the team continues to grow, this spirit and determination remains constant.
We work with clients across multiple sectors who share our mission to make a positive impact on people’s health and well being. Change for Good is our mission, and we stand by this in everything we do.
An agency built on solid foundations
Our founders, Chris and Neil, were previously directors at a multi award-winning health marcoms agency, that they helped build into one of the UK’s most celebrated and respected consultancies.
Having been friends since they were twelve (hence the name), they started the agency driven by a shared desire to do great work that they could be really proud of and that genuinely makes a difference.
Camaraderie remains at the heart of the agency culture, with a team of comms and creative specialists who are united by a passion for inspiring positive change.
