Brave Bison today announced that Buster Dover has joined the business, taking on the role of group COO. 

Formerly MD of Zinc Network and MullenLowe, Dover has worked in the creative industries since the late 1990’s. 


His career has spanned advertising, digital and social change agencies, from small independents to large network groups. 

Dover’s experience makes him uniquely well placed to lead Brave Bison’s current transformation, which saw the acquisition of Greenlight Digital & Commerce to bring digital marketing expertise to Brave Bison’s current network.

Hannah Kimuyu has also been promoted to Managing Director of Greenlight Digital. 

Formerly Director of Paid Media, Data & Analytics at the business, Kimuyu will lead on performance channels including paid media and SEO within the new proposition, using her knowledge of the Greenlight business and digital space to leverage new opportunities for present and future clients. 

Her appointment also heralds a new, more integrated way of working with existing clients, with paid and earned media sitting under the same senior management channels for the first time in the business’s history.

Both appointments demonstrate the appetite for growth and innovation begun with Brave Bison’s transformative acquisition of Greenlight Digital & Commerce, which completed on 1 September. 

By combining Greenlight’s strategic expertise and agility as a leading digital services provider with the reach and engaged audiences of their thriving digital media network, Brave Bison has created a new and compelling proposition for the digital marketing industry.

All other senior management across both businesses will remain, with Oli and Theo Green leading as Brave Bison’s Executive Chairman and Chief Growth Officer respectively, while Kevin Murray continues as Managing Director of Greenlight Commerce. Andreas Pouros, previous CEO of Greenlight Digital, and Warren Cowan, previous Chairman of Greenlight Digital & Commerce, remain as shareholders within the businesses.

“The COO role at Brave Bison represents a unique opportunity to apply so many aspects of what I have learnt over my career in a fast moving, entrepreneurial organisation” Dover said.  

“The constantly evolving nature of digital communications and technology presents so many possibilities for our client’s businesses as well as our own.  I am looking forward to working with the significant breadth of talent within the group to deliver some fantastic results.”

Kimuyu said: “I am thrilled to be stepping up as Managing Director of Greenlight Digital and moving onto a new chapter with Brave Bison. 

“Oli and Theo’s ambition and the experience Buster will be bringing to the leadership team, will be a game changer for the agency, our people and clients.”
