A former Tufts football captain spent decades studying a material most people reserve for special occasions. Now he wants its less visible properties working inside the things we use every day.

After two decades in advertising, Chris Valencius moved from selling familiar brands to translating unfamiliar molecules. At Evolved By Nature, his job is to make silk-derived biotechnology legible, useful and commercially real.
Evolved By Nature is a Boston-area biotechnology company that turns discarded silkworm cocoons into a liquid, renewable protein platform called Activated Silk. From that platform it builds a library of natural peptides and biopolymers used as petrochemical-free alternatives across three markets: clean skincare and cosmetics ingredients, biodegradable finishes for leather and performance textiles, and injectable biomaterials for medical aesthetics. Founded in 2013 by silk-chemistry veterans Dr. Gregory Altman and Dr. Rebecca Lacouture, the company has raised roughly $190M including a $120M Series C and counts Chanel among its investors and partners.
