About Julia Marsh and Sway

Julia Marsh is the CEO and co-founder of Sway, a material innovation startup scaling seaweed-based, home-compostable packaging. Julia spent over a decade designing brand and packaging systems for consumer goods companies, technology startups, and design studios around the world. Her work is driven by a deep passion for regenerative design and biological circularity.

Sway’s patented products match the vital performance attributes of conventional plastics and are designed to plug into existing infrastructure, enabling scale and massive impact. Unlike plastic, however, their materials are made from an abundant, regenerative resource and decompose into healthy soil after use.

In 2024, Sway was named a Fast Company World Changing Idea. In 2023, Sway won first place in the TOM FORD Plastic Innovation Prize. In 2021, Sway also won the Beyond the Bag Challenge sponsored by Closed Loop Partners and a consortium of major retailers. Sway’s solutions have garnered recognition from Vogue, Forbes, Business Insider, and Fast Company.

Sway is headquartered in the California Bay Area.
