Rebel Harbor was started in 2026 by Sarahlynn and Jeff. After years raising two kids, Sarahlynn is heading back to work on her own terms. Jeff builds websites by day. Nights and weekends go to the thing we'd rather be doing.

It started with Sarahlynn's favorite blends and a simple idea: good coffee is better shared. So we built a mobile cart and bring real espresso, not urn coffee, to weddings, markets and offices around Boston.

Down to earth (despite the spacesuits). No gatekeeping, just good coffee. We work with small New England roasters, pull every shot in front of your guests, and use the brand to do some good along the way. Friendly, and a little weird.

source

A short list of small New England roasters we trust. Traceable, seasonal lots, and we pay what they're worth.

02

taste

We cup their current lots and pick the one that fits your room, then order it fresh off that week's roast.

pour

Cart in, two baristas, four hours of service. Then we pack up, sweep the floor and vanish.
