This 4th series of The Catalysts podcast accompanies the new 2nd edition of the book that I have co-written with Eamonn Carey, called 'The Startup Lexicon’, which is a guide to the words, phrases, jargon and terminology used in the startup and tech world. In each episode Eamonn and I will discuss 4-5 key words that are crucial to the understanding of the world of start-ups.
