Tessa Callaghan is the CEO and co-founder of Keel Labs, makers of a seaweed-based yarn they call Kelsun. 

In case you didn’t know, the textile and fashion industries are a mess, and they contribute enormous amounts of waste to our planet. Tessa and her co-founders set out to create a fully functional yarn with a significantly lower environmental footprint than conventional fibers. They’re harnessing a biopolymer from kelp to achieve this, and kelp is one of the most regenerative organisms on our planet. 

They’ve raised tens of millions in funding for their concept, and I’m excited to see what comes next. Here’s Tessa Callaghan of Keel Labs.
