Series A
$15.0M

The London-based biomaterials startup secured $15m from investors including Alter Equity and JamJar Investments to expand its manufacturing network in the United States and Europe.

"Shellworks represents exactly the kind of innovation we need to see in the materials economy. They’re not just creating a better material, they’re building the infrastructure to make it accessible at scale. That’s what will drive real change and contribute to the plastic-free economy we are supporting at alter equity."
