Weapons of Mass Confidence
Kat Thomas is the author of Weapons of Mass Confidence, a timely and provocative
exploration of how AI can help close the confidence gap for women at work and beyond.
Built around her “Just Ask” philosophy, the book reframes AI as a practical, everyday tool for
turning hesitation into action, helping people navigate everything from career decisions to
personal health conversations with greater clarity and conviction. Kat is an in-demand voice
on confidence, visibility and the role of AI in shaping modern behaviour.
She is a creative entrepreneur and founder of Knock Three Times, a new earned-first creative
communications company built for the AI era. Previously, she founded the
multi-award-winning PR agency One Green Bean in Sydney in 2007, expanding it to London in
2015 before its acquisition by Havas in 2022. Over the course of her career, Kat has led
campaigns for brands including Virgin Atlantic, Nike, Google, IKEA, Ben & Jerry’s and Uber,
building a global reputation for culturally impactful, earned-led work.
Her campaigns have been recognised with more than 100 international awards, including
multiple honours at Cannes Lions International Festival of Creativity, where she served as
President of the PR Jury in 2024. Known for a distinctive blend of irreverence, playfulness
and cultural instinct, Kat’s work consistently puts audience attention first.
Alongside her commercial work, Kat is an active contributor to the creative industries,
regularly serving on global award juries and supporting initiatives that champion the next
generation of talent. Her perspective sits at the intersection of creativity, culture and
technology, with a particular focus on how new tools are reshaping confidence, influence
and opportunity for womankind.
