Mary Harcourt of CosmoGlo on Innovation and Scaling Your Business
You cannot scale what you have not built intentionally.
Shelby sits down with Mary Harcourt, founder and CEO of CosmoGlo, to talk about what innovation actually looks like from the inside of a beauty brand. Mary shares how her years behind the lash table gave her a front-row seat to a problem every lash artist knows but nobody had solved, and how that frustration became the fuel for building one of the most recognized tools in the industry. From early-stage product development to scaling a brand now trusted by 35,000+ lash artists and beauty professionals across 80+ countries, this conversation covers the kind of business fundamentals every lash boss needs to hear.
Whether you are behind the chair or thinking about your next move, Mary's story is proof that the best ideas come from people who have actually done the work.
