Full bio & headshot

Harriet is an activist, working at the intersection of advertising, climate change and misinformation. Her role at Media Bounty focuses on insight gathering and climate misinformation across a range of groundbreaking clients and projects from electric vehicles to green finance.
She co-founded The Conscious Advertising Network with Jake Dubbins of Media Bounty in 2018 and has since seen it gain international recognition, work with the UN, and grow to over 150 members from Virgin Media O2 to Accenture Interactive. She’s a former Mozilla Fellow, working with Consumers International to map the opportunities and impacts of AI enhanced advertising, globally.
"If you’re keen to find yourself working with a passionate, hugely talented, hard-working, versatile, fun-loving, solutions-focused professional in this field, then Harriet is more than likely to fit that particular bill. Working with her on both Collectively and the We Are Europe campaign was a joy."
