Paul Mellor is a self-certified pain-in-the-ass, asker of difficult questions and creator of advertising that makes Underdog brands famous.
He started the Ad Agency Mellor&Smith in 2009 in the midst of the banking crisis, and has been making sensible decisions ever since.
Mellor&Smith make Underdog brands famous by out-thinking the competition. Doing the thing, the biggest brand can’t, won’t or daren’t do.
What makes him unique? Somebody far cleverer than him once said "Paul reads the Financial Times and writes ads that go in The Sun."
Paul was also an Exec-Producer on the film Boiling Point, which was nominated for 4 BAFTA’s and was recreated as a 4-part series on BBC1 (which made his Mum proud).

Sam Cunliffe is Chief Client Officer and Co-Founder of Grove B2B, based in Australia.
A B2B career thoroughbred, she’s spent over 15 years designing and leading marketing activation programs for global, regional (APAC and EMEA), and local brands that actually make sense in-market. Her expertise spans audience design, activation architecture, and translating global frameworks into strategies that work, especially in APAC.
Sam’s known for getting on her soapbox about the average state of B2B (and anyone who says B2C and B2B are the same) and the industry’s obsession with generalized benchmarks. She finds the breadth of niche topics this space throws up fascinating (swears she’s fun at parties) and finds genuine satisfaction in driving business performance – for clients, for Grove, and with teams.
