Keel Labs began in 2017 as AlgiKnit, creating ocean-focused materials built from renewable resources. In 2022, Keel Labs was established as a platform for innovation, broadening its vision for the potential of the ocean to accelerate the planet’s development towards a more sustainable future.

Driven by the exploration of novel resources from the ocean, Keel Labs functions as a hub for the next generation of climate-focused solutions derived from nature. The company works at the nexus of design, science, and engineering to create impact-driven materials that harness the power of the ocean. Kelsun yarn, Keel Labs’ flagship product, is a seaweed-based yarn with a significantly lower environmental footprint than conventional fibers.
