Brave Bison promotes Hannah Kimuyu to CEO of integrated Performance and Commerce practice

London, 4th Feb: Today, media, marketing and technology company Brave Bison announces that former Managing Director of Performance, Hannah Kimuyu, has been promoted to the newly created role of CEO, Performance and Commerce.

Kimuyu will lead an expanded team of over 120 people across 30+ markets, focused on building integrated, audience-centric solutions across performance media and commerce technology for clients including New Balance, Curry’s, Asus, ProCook, Furniture Village, Ingenico, Target Sport and Banham Security.

The new ecommerce-centric practice will become the engine room of Brave Bison’s innovation in 2025 and beyond, encompassing the company’s already well-established AI team, who have spent the past 5 years pioneering leading proprietary tools such as AudienceGPT, a strategic planning tool powered by silicon audiences, and AdStudio an AI-enabled performance creative solution that delivers high performing assets at speed and scale—achieving triple digit increases in ROAS for clients including Seasalt Cornwall and The Travel Corporation.

Under Kimuyu’s leadership, the enlarged business will continue to innovate new, agile solutions at the intersection of media and technology with a particular focus on technical SEO migration, conversion rate optimisation, UX consultancy and bespoke performance measurement.

They will also continue to work in close collaboration with Brave Bison’s other practices: social and influencer agency, SocialChain, with whom they share a number of clients, and newly-acquired sports marketing agency Engage Digital Partners.

Kimuyu joined Greenlight Digital in 2004, rising to Managing Director as the business was acquired by Brave Bison in 2021. She is a Drum 30 under 30 winner, Campaign 40 over 40 winner, active member of the WACL community and regularly featured on the PMW Powerlist. Over the course of her career she has delivered award-winning work for the likes of Nespresso, New Balance, Superdry and ghd, with a particular focus on expanding brands internationally through performance media and pioneering new platform innovations.

A passionate advocate for diversity and inclusion, she has also worked tirelessly to drive systemic change across the media industry; spearheading Greenlight Digital’s involvement in the Advertising Association's All In Census, consulting on WPP’s Racism in Algorithms research and working with the Women’s Resource Centre, to help them fundraise through digital media, securing the charity a digital marketing budget for the very first time to deliver campaigns that promoted the safeguarding of women and girls across the UK.

Oli Green, Executive Chairman, Brave Bison commented: “I am thrilled to have Hannah stepping up to lead Brave Bison’s enlarged Performance and Commerce practice. She is an empathetic, driven and outcome-focused leader—implicitly trusted and respected by clients and her team alike.

As the lines continue to blur between technology, media and content, I have every faith that she and her team will help our clients outpace their competition by building truly innovative, agile solutions.”

Hannah Kimuyu added: “I couldn’t be prouder to have the opportunity to bring together two of the most innovative business practices in Brave Bison to help our clients join the dots between their media and commerce technology in support of future growth.

There’s a reason I’ve been part of this business for over twenty years – the people – I have so much gratitude for the committed, forward-thinking teams that have got us to where we are today, and I can’t wait to work with them all as CEO to build new solutions to tomorrow’s challenges.”
