Mark Debenham

B2B Growth Marketing & Operations Leader

Mark Debenham helps B2B marketing leaders work out what matters, what does not and what to do next. He has led growth marketing and marketing operations teams, bringing data, technology and customer insight together. He does his best work in the messy middle, when the numbers, the customer and the commercial reality are telling slightly different stories. Mark has spoken at HubSpot events in the US and Europe. Based in London, he is kept on his toes by his two tortoiseshell cats.
