Dave Cornthwaite

Author, Filmmaker, Yes Man


Dave has been an increasingly familiar figure in the UK adventure scene since quitting his job as a really bad graphic designer in 2005.

Developing a wide range of storytelling skills and using these to share a series of unique expeditions, adventures and social projects, Dave’s reputation as a Yes Man is now confirmed.  At his core, he is a record-breaking adventurer who has travelled over 19,000 miles as part of the amazing Expedition1000 project: 25 journeys of 1000 miles or more, each using a different form of non-motorised transport.

His uniquely entertaining and motivational keynote presentations have been enjoyed on six continents and Dave has also written three books.  As an award-winning filmmaker and social media expert, Dave has created hundreds of shorts and occasionally makes films and creative campaigns for other individuals and brands, as well as prolifically sharing his journeys as he goes.

In 2012 Dave founded SayYesMore, an enterprise based on a philosophy of turning strangers into friends, breaking down fears and hurdles, and enabling people of all ages to redesign their lives and jobs. With the first ever Yestival in October 2015 and the creation of the ever-growing YesTribe, Dave’s passionate advocacy of adventure as personal development has contributed to hundreds of individuals heading off on their own journeys, big and small.

At TEDx Square Mile Dave will focus on developing an adventurous attitude and the importance of exploring our own back yard; what it means to have a growth mindset and take personal control of our lives and decisions; and using adventure to battle mental health in an increasingly busy world.
