Benjamin Cook

Benjamin Cook is the founder, CEO and board chairman of Zirconia Inc., a Tukwila, Washington advanced-materials company building water-borne ceramic coatings that chemically bond to concrete and steel at room temperature - effectively turning aging infrastructure into something close to liquid granite. A self-described green technologist with three decades of cleantech ventures behind him, Cook trades on a single conviction: the cheapest and greenest building is the one you never have to tear down. Before Zirconia he founded GeoTree Technologies, an underground-pipe restoration firm sold for a 5x investor return, and earlier still he traded a planned career in pediatric medicine for a life spent removing toxins from the built environment.
