Co-founder & CXO
Hollie is a registered osteopath with a Graduate Diploma in Psychology and a passion for behaviour change. Working closely with patients gave her a deep appreciation for how stress, emotions, and habit loops shape people's behaviours. After seeing how many young adults had become unintentionally dependent on vaping, often wanting to quit but lacking the right tools and support, she co-founded Sigh to create a more human, science-led approach that helps people understand cravings, break automatic habits, and regain control.

After founding and operating his own healthcare clinic and previously exiting a consumer business, he co-founded Sigh to create a more effective, science-led approach that helps people regain control of vaping.
