Claire started her career in non-fiction publishing before getting distracted by the digital world. She spent five happy years commissioning arts and culture projects that use new technology, then set up a mass-participation project to encourage people to sow native varieties of wild flowers for the Royal Botanic Gardens, Kew in London. She is currently Head of Copy at Quietroom, a team of business writers, trainers and strategists.
