About Shellworks
Shellworks is a London biomaterials company founded in 2019 by Insiya Jafferjee, Amir Afshar and Ed Jones (Royal College of Art / Imperial College) that designs and manufactures Vivomer—a bio-based, compostable PHA packaging polymer fermented from second-generation feedstocks such as used cooking oil—as a plastic alternative for beauty and personal-care brands. Vivomer is intended to perform like conventional plastic in use then biodegrade without microplastics; the company reports cost competitiveness with glass and aluminium at roughly five million units produced and supplies pipette droppers and cream containers to brands including Bybi, Liha, Sana Jardin and Haeckels. In March 2026 Shellworks raised a $15 million Series A led by Alter Equity, with Nat Friedman (NFDG), JamJar and existing investors Founder Collective, LocalGlobe and Third Sphere, to scale manufacturing across the UK, Europe and the US and expand mass-market partnerships.
