In their Inventor's Studio course at Rensselaer Polytechnic Institute taught by Burt Swersey, Eben and Gavin developed and then patented a method of growing a mushroom-based insulation, initially called Greensulate before founding Ecovative Design in 2007.

[3] Since 2008, when they were awarded $700,000 first place in the Picnic Green Challenge[4] the company has developed and commercialized production of a protective packaging called EcoCradle[5] that is now used by Dell, Puma SE, and Steelcase.

[8][9] In 2014 their material was used in a brick form in 'Hy-Fi', a 40 feet (12 m) tower displayed in New York by the Museum of Modern Art and they started selling 'grow-it-yourself' kits.

[19] Architect David Benjamin of The Living, working with Evovative Design and Arup, built 'Hy-Fi', a temporary 40 feet (12 m) external exhibit at the Museum of Modern Art in New York City in 2014.

[10] Working with the University of Aachen, Dutch designer Eric Klarenbeek used 3D printing technology to gown a chair without using plastic, metal or wood.

[25] A season six episode of CSI: New York, also featured the insulation as lab technicians tested the materials' flame resistant properties after finding particles on a victim's clothing.
