Eliot Brooks is the CEO and co-founder of Cocoon.

Cocoon is driving the industrial circular economy, starting with a process that helps the steel industry continue supplying a critical feedstock for cement production. This feedstock is increasingly at risk as steelmaking transitions from coal-based blast furnaces to lower-emission electric arc furnaces.

Cocoon was founded on the realization that as industries decarbonize, certain process changes disrupt circular supply chains. The connection between the slag byproduct of steelmaking and the demands of cement production is their starting focus. Earlier this year, Cocoon announced a $5.4 million pre-seed round led by Wireframe, Gigascale, SOSV, and Celsius Industries.
