Growth Council

We’re helping members stand out, win the right clients and tee-up profitable long-term relationships in the UK and overseas.

About the council

Growing your business – and avoiding the pitfalls – is easier when you get the support, advice and insight you need. The Growth Council brings together peer agencies to share their experiences and learn from each other. We source expert advice, contacts and funding sources. And we host workshops, events and trade missions to make international growth easier.

Robin Bonn, Founder at Co:definery

Robin is a founding member of the BIMA Growth Council and the Founder of Co:definery, a management consultancy advising agency CEOs on standout, conversion and profit.

He’s spent 20 years driving growth for startups, indies and global networks, across a range of emerging and traditional disciplines.

He’s also a mentor – or ‘man-bassador’ – for SheSays, an organisation helping women rise to the top of the creative industries, and a columnist for Marketing Week.

In his old life, Robin led winning pitches for the likes of Skype, Eurostar, Fujitsu, Experian, Spotify, P&G, ITV, Microsoft, Facebook and Ford, to name a few. He’s also a former member of the IPA’s New Business Group and Direct Marketing Association’s Agencies’ Council.

But while client challenges got harder, he saw agencies increasingly lag behind, with old-fashioned ‘best practice’ models for growth, new-business and profit dating badly.

Since founding Co:definery, he’s advised the CEOs and Founders of dozens of agencies; repositioning, refocusing and reorganising them to increase standout and win more often.
