Mark Shami is a New York entrepreneur and designer who turned a childhood spent behind the counter of his father's Diamond District jewelry shop into The M Jewelers, one of North America's largest online personalized-jewelry brands. A former touring pop musician who started out selling graphic tees, he launched The M Jewelers in 2014, built it into a multi-million-dollar direct-to-consumer label with collaborations spanning Nike and Live Nation, and earned a spot on the Forbes 2019 30 Under 30 list for Art & Style. He now also serves as Chief Marketing Officer of GUIZIO, the women's fashion label founded by designer Danielle Guizio.
Andrej Strojin is the co-founder and CEO of HAVERHILL, a Warren, Rhode Island fine-jewelry house that makes 14k gold, birthstone-personalized pieces to order rather than in advance. A Slovenian-trained mechanical engineer and former Deloitte and Strategy& consultant, he met fifth-generation jeweler Haverhill Leach on a dating app in 2018, married her four months later, and turned her artisan brand into a fast-scaling direct-to-consumer operation. When COVID shut down suppliers before Mother's Day 2020, the couple built a jewelry assembly line in their garage and cut turnaround from seven days to one. Under Strojin the company has quadrupled sales, reached $16M in 2024 revenue, and landed on the Inc. 5000 three years running.
