William Playford, the inventor and founder of 9Barista, developed a passion for building complex thermodynamic machines since 2006. The 9Barista was designed to use as few resources as possible and to last as long as possible, whilst not compromising at all on espresso extraction performance. Since founding the company we've built a fabulous team at 9Barista, and a wonderful community of customers who share similar values. We're always seeking ways to improve how we run our company so that we can reduce our impact on the planet and make a positive contribution to society.
