ecoSPEARS is the exclusive licensee of patented NASA-developed environmental technologies. ecoSPEARS imagines a world where everyone has access to clean water, clean food, and clean air.


Kuleana is creating the next generation of seafood with plants and biotechnology.

After going through Y-Combinator's S20 batch and raising $6.5M Pre-Series A, Kuleana has products across the country with an initial foodservice focus. Products will be available online in Q4 2021 and targeting retail in 2022.


Oceanium has developed a proprietary, “green” biorefinery technology to process seaweed into high demand products including plant-based food & nutrition ingredients (protein, fibre) and circular life-cycle materials.

By “making the market” for farmed seaweed, Oceanium will catalyse the sustainable seaweed farming industry and pioneer the development of a new, environmentally friendly aquaculture industry in the Western Hemisphere and developing world.


Sway combats plastic pollution and its devastating effects by replacing single-use plastics with packaging made from seaweed.

Sway's technology drops into traditional plastic infrastructure, while simultaneously replenishing ocean health, sequestering carbon, promoting benevolent materials, and ultimately creating a more inclusive climate movement. The company is based in Berkeley, California, and works with seaweed farmers across the Western Hemisphere.


Planblue is building up a global seafloor database in high detail using our Underwater Satellites, to foster a sustainable Blue Economy.

Why the seafloor? It plays a key role in solving climate change, biodiversity loss and plastic waste pollution. Unfortunately, we cannot properly grasp the seafloor's true economic and ecological value. We do this by combining AI with advanced imaging and underwater navigation.


Returnity replaces single-use shipping and delivery packaging by designing, manufacturing and implementing reusable packaging and circular logistics systems.

Used for over 500,000 shipments per month, their packaging addresses the negative impacts from the rapid growth in direct to consumer shipping.

SeaForestation Co

SeaForestation Co provides deepwater solar irrigation services and equipment for replete seaweed cultivation across the oceans to meet food security needs, ecosystem life support and carbon export applications.

Restoring natural upwelling with deepwater irrigation of seaweed platforms restores production rates lost due to climate disruption, while staving off the Permian Mass Extinction one kelp forest at a time. SeaForestation Co addresses billion-dollar markets in food, feed and agricultural amendments while regenerating critical marine ecosystems and measuring carbon export to the deep ocean.

Full Cycle Bioplastics

Pioneers of a regenerative economy, Full Cycle Bioplastics redefines waste through material alchemy. We are a biotech company that addresses the issues of plastic pollution, food waste, and climate change by transforming organic waste into Polyhydroxyalkanoate (PHA), a high-performing compostable alternative to oil-based plastics. 

Full Cycle's proprietary bacteria-powered technology converts mixed organic waste streams such as inedible food waste, agricultural by-products and dirty paper and cellulosic wastes into PHA. We help organic waste generators and processors profitably move towards circularity while replacing oil-based plastics across the supply chain.
