21 in 21: Joe Carlo on How Bitcoin Changed Pink Owl Coffee Forever
Haley Berkoe sits down with Joe Carlo, co-owner of Pink Owl Coffee, a café that began in San Rafael, California, and has since expanded to three locations across the Bay Area. Pink Owl is one of the earliest Square merchants to integrate bitcoin into its business model. For several years, Joe and his partner Saandra have been converting a percentage of sales into bitcoin as part of their long-term savings strategy, and they recently joined Square’s beta program to begin accepting bitcoin payments directly, ahead of the public launch on November 10th.
Joe shares how he first discovered bitcoin, what inspired him to use it as a small-business owner, and how he’s helped educate both customers and staff on what it means to pay (and save) in bitcoin.
