Episode 407: Seth Rosen - CEO & Co-Founder, CustomMade

from The VentureFizz Podcast · host VentureFizz

Episode 407 of The VentureFizz Podcast features Seth Rosen, Founder & CEO of CustomMade. A common theme that you’ll hear throughout this interview is the importance of resiliency. Sure - the media loves the story of the latest company that has achieved $100M ARR in a month (I’m obviously kidding), but the overwhelming majority of businesses are a grind. It’s about taking a bunch of punches, getting back up and figuring it all out. It’s not all rainbows and butterflies, which is why I was excited to interview Seth. The story of CustomMade has lots of twists and turns… from rapid growth… to later salvaging the company by structuring a deal with Wayfair to acqui-hire their employee base… to the insanely successful reboot! Today, CustomMade is a leading online custom jeweler that specializes in creating personalized, one-of-a-kind jewelry pieces, such as engagement rings, wedding bands, and more. The platform simplifies the entire custom process, helping buyers create their vision and working with master jewelers to bring it to life.
