Cressida Granger is the owner of, a name you might actually remember as being the original creator and inventor of the famed lava lamp. She is a more recent member of the ECF community, and I wanted to get her on to talk about her story and her business because it is so incredibly interesting. 

Listen in as Cressida shares how she manufactured a back-of-the-napkin deal for the iconic lava lamp brand, what happened when people found out that her patent on the lava lamp had expired, and why the business chose to move away from wholesale. We also discuss the Brexit challenges that have become part of the territory of shipping from Britain, as well as why Mathmos is making the move to a new e-commerce platform (and which one it is).
