Tenacity with Ivory Tenee

Each episode is an honest conversation with founders and entrepreneurs who chose to keep going when things got hard.
Tenacity Episode 4: Mary Harcourt, Inventor and Founder of CosmoGlo
The best inventions usually start with the same moment: someone who knows an industry inside and out finally gets fed up with a problem nobody else has bothered to fix.
That is exactly what happened with Mary Harcourt.
After years as a lash artist and salon owner, Mary kept running into the same frustration: the lighting available for treatment rooms was not built for the precision that professional beauty work actually demands. No product on the market solved it. So she built one herself.
CosmoGlo is now a patented professional beauty lighting brand trusted by 35,000+ beauty professionals across 80+ countries, including lash artists, estheticians, permanent makeup artists, and medical aesthetic professionals. What started as a gap nobody was filling became one of the most recognized innovations in the beauty and aesthetics industry.
In this episode, Mary sits down with Ivory to talk about what it takes to go from spotting a problem to building a patented product, the tenacity required to push through the unknowns of launching something entirely new, and why the struggles along the way were part of what made it work.
