What Sway does
Sway Innovation Co. is a Bay Area-based materials science company founded in 2020 by Julia Marsh (CEO) and Matt Mayes (COO) that develops seaweed-based, home- and industrial-compostable bioplastics designed to replace single-use plastic packaging. Its core technology is TPSea™ (Thermoplastic Seaweed Pellets), a patented, certified 100% biobased biopolymer pellet that, despite seaweed's natural tendency to burn when heated, can be melted and processed through standard plastic manufacturing infrastructure. TPSea™ underpins two flexible-film sub-products — TPSea Flex™ (a majority-biobased film blended with certified home-compostable polymers) and Firstwave™ (a 100% biobased, fully transparent film made via a liquid-based process) — which in turn are converted into finished goods including Sway Polybags, Die Cut Handle Retail Bags, and Seaweed Windows. Sway does not own conversion or manufacturing assets at scale; it operates an "ingredient brand" model in which pellets and films are sold to a network of packaging distributors and converters (EcoEnclose, A New Earth Project, Atlantic Packaging, and Charter Next Generation) that handle compounding, extrusion, customization, and fulfillment before resale to end brands.
Sway's customer base is led by apparel and fashion brands — including the Sway Innovation Coalition of prAna, Faherty, Florence, Alex Crane, J.Crew, Vivobarefoot, Noah, Thistle, and Ales Grey — and has expanded laterally into food/confectionery (TCHO), personal care (Dr. Bronner's, Ocean and San), sports and outdoor (Burton, Florence Marine X), and stationery (Graf Lantz). Revenue flows through three primary channels: (1) material sales via distributors (TPSea Flex™ and Firstwave™ films and TPSea™ pellets), (2) custom material co-development captured via a Typeform inquiry form on the products page, and (3) a 1% for the Planet member commitment that directs 1% of sales to environmental nonprofits (with the Biodegradable Products Institute designated as a partner in 2026). Pricing is not publicly disclosed; sales are quote-based, with pay-as-you-go unit pricing on stock SKUs and bespoke contracts for custom formats. The company has raised approximately $8.1M in equity (notably a $5M round in December 2023 led by Third Nature Ventures) plus a $1.5M U.S. Department of Energy grant jointly with Umaro, and employs ~11 people, with a team weighted toward materials engineering, R&D, and supply.

Revenue model
- Material Sales via Distributors: Sway sells its seaweed-based pellet (TPSea™) and film (TPSea Flex™, Firstwave™) formulations to a network of packaging distributors (EcoEnclose, A New Earth Project, Atlantic Packaging) who convert the materials into finished packaging products (polybags, die-cut handle retail bags) and sell to brands across industries. This is Sway's primary revenue stream as an ingredient brand.
- Custom Material Co-Development: Sway offers custom material formats via an Inquiry Form for brands seeking bespoke packaging solutions, indicating a custom-formula/pilot revenue stream for enterprise brand collaborations.
- 1% for the Planet Commitment: Sway has been a certified 1% for the Planet Business Member since 2020, donating 1% of annual sales to environmental nonprofits (including BPI as a designated partner in 2026), representing a margin contribution rather than a primary revenue line.

Sway product offering
Product offeringCore offering
Sway is a material innovation company that develops and sells seaweed-based compostable biopolymer materials. Its core offering is TPSea™, a patented category of thermoplastic seaweed pellets certified 100% biobased that can be processed through standard plastic manufacturing equipment, plus two flexible films (TPSea Flex™ and Firstwave™) used to produce finished packaging products such as Sway Polybags and Die Cut Handle Bags. Sway operates as an ingredient brand, selling materials to packaging distributors and brands across apparel, beauty, food, and outdoor categories.
Product overview
Sway is a California-based materials science company offering a unified seaweed-based biopolymer platform centered on TPSea™ — its patented, certified 100% biobased thermoplastic seaweed pellet technology developed in its San Francisco Bay Area lab. The TPSea™ core technology flows through traditional plastic manufacturing and underpins two flexible-film sub-products (TPSea Flex™ Film and Firstwave™ Film), which in turn are converted into finished packaging products including Sway Polybags (shipping), Die Cut Handle Bags (retail), and Seaweed Windows (window packaging). Sway also offers Custom Formats (material co-development) and distributes its innovations through a network of packaging partners including EcoEnclose, A New Earth Project, and Atlantic Packaging, supporting brands across fashion, beauty, cosmetics, sports, and outdoor industries. The portfolio is anchored by the tagline "From Sea to Soil," reflecting Sway's circular economy design philosophy of regenerating natural systems through compostable, seaweed-based replacements for hard-to-recycle single-use plastics.

Sway competitors and assessment
Company assessmentDirect peers
- Notpla: London-based seaweed packaging company producing flexible films, sachets, and takeaway containers from seaweed. Most direct competitor in seaweed-based flexible packaging, pursuing the same fashion and food-service brands and the same home-compostable value proposition.
- Loliware: U.S.-based seaweed-based biopolymer company producing straws, cups, and cutlery. Competes in seaweed-derived flexible and rigid packaging formats targeting foodservice and consumer brands, with comparable drop-in compostable positioning.
- Umaro: Seaweed-to-protein/bioplastic company and Sway's joint DOE grant recipient. Competes directly in seaweed-derived bioplastics with overlapping R&D and U.S. Department of Energy relationships.
- Tipa: Israel-based developer of compostable flexible packaging films for food and apparel. Competes in certified home- and industrial-compostable films with comparable TUV-style certifications and similar brand customers in fashion and CPG.
Emerging players
- Cruz Foam: Santa Cruz-based company producing chitosan (crustacean-shell-derived) foam packaging as a plastic replacement. Adjacent biobased protective packaging for shipping and consumer goods, targeting overlapping sustainability-driven CPG brands.
- Shellworks: U.K. startup producing compostable packaging from shellfish waste. Comparable biobased, compostable positioning for premium beauty and personal-care brands, though feedstock differs.
Broad incumbents
- NatureWorks: Global PLA bioplastic incumbent supplying packaging, foodservice, and consumer goods. Represents the established biobased alternative that Sway's seaweed story must displace in brand procurement decisions.
- Charter Next Generation: Major legacy specialty film manufacturer and Sway's flagship co-development/converter partner. Relevant as both distribution channel and competitive benchmark for scale manufacturing of biobased films.
- EcoEnclose: Sustainable packaging distributor and Sway's primary converter partner for Sway Polybags and Die Cut Handle Bags. Comparable as a sustainable packaging go-to-market that could expand private-label or partner-brand alternatives.
- Atlantic Packaging: Packaging distributor and converter running the New Earth Ventures investment arm (which includes Sway as a portfolio relationship). Comparable as a packaging-distribution platform with both customer overlap and an investment vehicle that could finance competing materials.
