Originally developed by Seb Paquet, Project Kitchens is a wonderful tool that can help propel early stage ideas into concrete next steps
The format brings together a small number of people who have projects they would like assistance with and puts one project at a time under the spotlight for around 25 minutes. Generally 3-4 projects can be covered in a 2-hour Kitchen. A Chef facilitates; with the role of creating an atmosphere of trust, keeping things rolling, and avoiding wasting time through the process.
