Alistair O’Sullivan

Managing Director,


Alistair is one of FEOs youngest members, a local entrepreneur who founded an ambitious and disruptive digital marketing, design and advertising agency, called Diony.

After running several ventures while studying in education, he decided the educational system wasn’t for him, and left to set up Diony with no initial investment, clients, or following. From setting up in December 2016, Diony not only boasts a nation-wide brand awareness and client base but is also very much recognised as a strong, innovative brand and up an coming digital start-up within Hull itself.

With a team of 5, and offices based in Hull City Centre, Diony works with multiple markets and clients of all types and sizes in places across the UK, from national brands like Sports Direct, to your local independently owned businesses and start-ups.

Diony is a company that supports its own. It backs the vibrant culture of Hull and its quickly developing economy through working in partnership with local businesses, organisations and individuals. Alistair and his team are very proud of their roots in Hull and take pride in offering young, local designers and digital marketeers the opportunity to develop their new or existing skills via work experience placement schemes within the company, as a means to help nurture and develop the upcoming talent of the industry’s future.

Resilience, drive, and resourcefulness would be his top three traits to setting up any business.
