The Guys

Guy 1

Kirsten Geary

planning director

My 15 plus years’ experience working client-side for some of the UK’s biggest food and drinks companies have instilled in me a real commercial focus, which helps direct the planning team at Guy & Co to ensure that all our ideas are grounded in consumer insight and commercial potential.


Starting my career with Nestle UK, I held a number of brand management positions on a variety of big and small brands, including invaluable experience within the innovation team and responsibility for the Disney license. Moving to Scottish & Newcastle to initially work on Miller Genuine Draft, I spent 8 years working across their portfolio, managing the on-trade rollout of Fosters Super Chilled and core brand communications and innovation launches for Kronenbourg and Strongbow, including Kronenbourg Blanc and Strongbow Jacques.


The planning approach at Guy & Co is to always ensure that we ‘think like a client’. We apply commercial rigour and develop strategies grounded in genuine market insight to all our creative ideas to ensure that we maximise commercial gain for our clients.

Guy 2

David Guy

Managing Director

Starting my career in major BTL agencies, I worked on confectionery, soft drinks and grocery FMCG brands. Account directing the Tango account, at its irreverent and mischievously funny peak, was an early career highlight. To help increase the creative quality of new ideas, I trained as an innovation facilitator with industry leaders, !WHATIF? This led me into innovation positions where I created agency systems to improve pitch strike-rates and the commercial quality of ideas for clients from drinks (a lot of drinks brands!) to automotive to infant care.


I founded and ran Billington Cartmell’s first integrated creative shop in Edinburgh and worked on brand innovation and activation projects for distillers Edrington, Scottish food and drink brands and a range of blue-chip financial and professional services clients. With 20 years’ experience of working for great agencies, I knew what I wanted and didn’t want to bring from my agency experience in setting up Guy & Co. I also knew there was an opportunity to create a new proposition for a creative agency with a difference. In 2013, I founded the agency and as MD, I have set myself 2 key ambitions: to cultivate a world-class creative agency which can substantiate why it’s ideas are great; and to properly reward our high-performing people to deliver great results for our clients.

Guy 3

Cat Summers

Client Services Director

I hail from an advertising background, having started my career at one of Scotland’s largest and most reputable agencies, The Union. There I worked with a real mix of clients across retail, drinks, and the public and third sectors, managing brand strategies and producing advertising campaigns for the likes of Scottish Development International, Prostate Scotland and Government initiatives.


It sparked a real interest in social marketing and I moved client-side for a period with the Energy Saving Trust, before I stepped back into agency life with David at Billington Cartmell, working on global campaigns for the likes of Panasonic. Being part of Guy & Co from day one has been an exhilarating journey, helping to pick out the best bits from our agency backgrounds and shape something Great.


I strive to develop systems that make our creative ideas and execution the best they can be, and to bring on a great team of guys from diverse backgrounds who share our ambition, think bold and who make talking shop over 5 o’clock Friday beers genuinely fun. And when you can make professional friends of clients and do the same, it’s all the better.
