With the help of his co-founder Gabriel Bolduc, William launched KaseMe in 2016 and successfully built a fast-growing e-commerce business.

Having sold millions of phone cases worldwide by leveraging influencer marketing and digital advertising as key growth drivers, KaseMe is now shifting its focus to new strategies to capture additional market share in Canada and the United States. This includes opening twelve physical stores by the end of 2026, expanding into retail through partnerships with brands like Simons, and producing custom-branded phone cases for companies such as Beneva, Desjardins, and the Montreal Canadiens through their new division, KaseMe Affaires.

KaseMe is a certified B Corp with over 90 employees. The company promotes transparent management and offers benefits that reflect the value of its team—such as their unlimited vacation policy. All of this is done with a strong awareness of their social and environmental impact, taking concrete, measurable actions to reduce their current and future footprint.
