Co:definery was founded by Robin Bonn. He’s spent 25 years driving agency growth for global networks, indies and start-ups, across a range of emerging and traditional disciplines.
​
In his old life, Robin led winning pitches for the likes of Spotify, P&G, Experian, ITV, Microsoft, Skype, Facebook and Ford, to name a few. But as client challenges became more complex, he saw agencies struggling to keep up – clinging to outdated business models and so-called ‘best practice’ that no longer delivered.
​
Since then, Robin has been on a mission to de-commoditise agencies. A trusted advisor to some of the world’s most renowned agencies, he helps CEOs and Founders reimagine what differentiation looks like, enabling agencies to scale faster, command a premium and attract the best talent in the industry.
​
Beyond consultancy, Robin is also an executive coach, a Marketing Week columnist, a founding co-chair of BIMA’s CEO & Leadership Council and a mentor for SheSays. He’s served on the IPA’s New Business Committee and the Direct Marketing Association’s Agencies’ Council. He’s the author of Market of One and the host of The Immortal Life of Agencies, a podcast dedicated to fresh thinking and optimism in agency leadership.
​
Away from work, Robin is a dad of two daughters, a woeful runner, an amateur artist, and a professional cat botherer.

Vivian Yong began her advertising career in 1999, working at M&C Saatchi and Ogilvy & Mather in Hong Kong. She then moved to London, where she became an art & cultural columnist for Hong Kong readers. In 2012, she joined W+K Shanghai as a creative director, bringing with her a multicultural background and a unique global and local perspective.
​
She has parlayed this into a knack for creating integrated campaigns for global brands such as Nike, BMW, Levi's, Corona, and HP Omen. And she was the leading force behind one of the socially most successful campaigns for Tiffany and Ikea, which remarkably grew their fanbase and engagement.
​
Since Vivian took the helm as Executive Creative Director, the office has experienced significant growth not just in size but also in the diversity of talent and clients. Her creative leadership was the driving force behind Nike's hugely successful woman campaigns and its first Chinese New Year campaign. She was honored as one of the “11 Global Creative Leaders Shaping the World’s Most Innovative Marketing” by Adweek in 2020 and ‘Women to Watch Greater China 2021” by Campaign Asia.
