Moment founder Marc Barros makes accessories for mobile phones. His company’s optical glass lenses screw onto special mounting brackets that you fasten to your phone, much improving the quality of your handset’s camera. The company’s cases also feature physical shutter buttons with DSLR-like behaviors. Moment’s lenses and cases have taken off among mobile photo enthusiasts; they’re really great. But we didn’t bring Marc on to plug product. He’s here to talk about the smartphone accessories business. From design to marketing, from crowdfunding to manufacturing, it’s a wooly world, complete with copycats, bankruptcies, and brand managers who focus all of their marketing on Amazon search. Marc’s insights are invigorating and informative, and we hope you enjoy our talk as much as we did when we taped it.
