178. Pretty in Pigments: Jesse Adler Colors the Future with Pitri

Episode notes

Karl and Erum talk with Jesse Adler, founder of Pitri, about why color is not just aesthetic, but chemical, biological, and deeply tied to human and environmental health. Jesse traces their path from biomolecular science and biodesign into building fungal pigments that can replace synthetic and animal-derived colorants, starting with the beauty industry as a high-margin, ingredient-driven entry point. The conversation explores how consumer expectations and industrial infrastructure were built around petrochemical dyes, why biological materials are often unfairly judged against synthetics, and what it takes to create drop-in, high-performing pigments from living systems. Along the way, Jesse reframes color as a functional feature in nature, shares early experimentation stories, and points to future opportunities like multifunctional pigments and the “holy grail” of opaque white. Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and interview the leaders and influencers changing the world by growing everything. Biology is the oldest technology. And it can be engineered. What are we growing?
