Ocean Powered Progress

our mission

We are students of the sea, seeking to understand how the ocean can be used to build a zero carbon future. We study how we can harness the ocean’s natural rhythms to decarbonize the planet, restore habitats, and help people live healthier lives.

Our Farms


Premium Maine Oysters

Chock-full of zinc and omega 3 fatty acids, oysters are an immune-boosting, mood elevating, superfood. And best of all, they have a small carbon footprint as they need no fertilizer, feed, or cleared land to grow.

Our dedication to the oyster’s maturation process sets Running Tide oysters apart. Nurtured from our own hatchery to our hand-picked grow-out areas in Casco Bay, Running Tide oysters have deep cups, thick edges, and a beautifully consistent size and shape. Our oysters never touch the bottom, and as they grow they take on the sweet flavor of Maine’s pristine waters.

Our Team

Employing a talented team in Maine.

Our office is located at the Marine Trade Center in Portland. This hub of the working waterfront is home to many fishing businesses and marine services. Our hatchery, located at Mitchell Field in Harpswell, utilizes state-of-the-art technology to grow high quality, disease-resistant oysters that thrive in Casco Bay. Working alongside other entrepreneurs in the region, we fabricate our oyster gardens at TechPlace, located at the former Naval Air Station in Brunswick.
