We're honoured to have Wouter Blok as our guest. Wouter is VP Growth Marketing at GetYourGuide, the European platform to book guided tours. He originally trained to become a pilot, no less with KLM. Flying wasn't as exciting as marketing though, so he joined several startups. Wouter later went on to Google, Coolblue, and Sprint. Now, he's conquering the world with GetYourGuide, which was founded in 2009 and has sold over 120 million tickets. How have they managed that?
