Ajikumar Parayil
He spent years teaching bacteria to build molecules that used to take entire fields of plants. Then he bet a company on getting those microbes out of the lab and into million-liter tanks.
Laura Katz
Laura Katz is the founder and CEO of Helaina, a New York biotech company that uses precision fermentation to produce human-identical bioactive proteins. Its first product, effera, is the world's first commercially available human lactoferrin made through yeast fermentation. A food scientist by training and once NYU's youngest adjunct professor in Food Science, Katz started the company in 2019 from her Lower East Side kitchen after hearing a podcast about the black market for breast milk. She has raised more than $80 million to move Helaina from research into a commercial ingredient business.
Fengru Lin
Fengru Lin is the co-founder and CEO of TurtleTree, a biotech company making dairy proteins without cows. A former Google account manager who took up cheesemaking as a hobby, she went hunting across Asia for clean raw milk, was horrified by what she found on the farms, and started a company to make milk in a lab instead. TurtleTree pivoted from full cell-cultured milk to precision fermentation, and now produces lactoferrin, a high-value milk protein once called 'pink gold,' using microbes instead of herds. She has raised roughly $44 million and made EDGE's 35 Under 35 and Her World's Young Woman Achiever lists.
Shannon Nangle
Shannon Nangle is a microbe-wrangling scientist turned CEO who co-founded Circe Bioscience to make fats, oils, and even chocolate out of thin air. Her company feeds carbon dioxide, water, and electricity to engineered microbes that grow like plants and excrete valuable molecules, producing food and industrial ingredients in a carbon-negative way. Spun out of Harvard's Wyss Institute in 2021, Circe made what it calls the world's first gas-fermentation-derived chocolate and has raised over $17 million to scale a manufacturing process Nangle spent six years building.
Eric Abbate
Eric Abbate is a synthetic-biology scientist turned CEO who led Solar Biotech, a Virginia-based startup building solar-powered, water-neutral fermentation plants to make biodesigned cosmetics, food ingredients and bioelectronic components. A UC Berkeley-trained molecular and cell biologist, he ran high-throughput genome-engineering and analytical biochemistry teams at Inscripta and was corresponding author on a widely cited paper on optimizing strain engineering for industrial-scale production. He steered Solar Biotech from lab science toward a modular 'BioNodes' manufacturing model before the company entered Chapter 11 in 2024 with plans to sell its assets and reboot.
Meijie Wang
Meijie Wang is the co-founder and CEO of MetaNovas, an AI-driven biotech that designs functional peptides for skincare, supplements and drug discovery. A former NVIDIA AI infrastructure engineer who built VR games and worked on AI at Stanford's School of Medicine, he now runs a Silicon Valley and Shanghai operation whose knowledge-graph platform aims to compress the decade-long hunt for new bioactive ingredients into something far shorter. MetaNovas counts L'Oreal, Beiersdorf, Haleon, Takeda and Unilever among its partners and raised a Series A led by GL Ventures.
Shawn Manchester
Shawn Manchester is the CEO of Triplebar, an Emeryville-and-Oakland based biotech building generative AI 'genome language models' paired with ultra-high-throughput phenotypic screening to slash the cost of biologic therapeutics and food proteins. A chemical engineer by training (BS Brown, PhD MIT), he was the lead scientist in the first AI-versus-human strain engineering contest at Zymergen before joining Triplebar in 2021, where he rose from VP of Product to COO to CEO in March 2025.
Ryan Pandya
Ryan Pandya co-founded Perfect Day in 2014 with the audacious goal of making dairy without cows. Using precision fermentation, the Berkeley-based biotech raised nearly $800 million, built partnerships with Fortune 500 food companies, and proved that animal-free whey protein could reach global markets across dozens of product categories. After a decade at the helm, Pandya stepped down as CEO at the end of 2023 to pursue future ventures, leaving behind a company that had fundamentally shifted the conversation around sustainable dairy.
Arturo Elizondo
Arturo Elizondo is the co-founder and CEO of The EVERY Company (formerly Clara Foods), the precision fermentation biotech pioneering animal-free egg proteins used by food brands worldwide. Born in Laredo, Texas, educated at Harvard, and seasoned by stints at the White House, USDA, and Credit Suisse, he co-founded the company in 2014 after meeting a cell biologist at a food-tech conference. Under his leadership, EVERY has raised over $471M, launched the world's first animal-free egg protein into Walmart, attracted actress Anne Hathaway as an investor, and earned Elizondo the EY Entrepreneur of the Year 2023 Bay Area Award. His mission: end factory farming by making fermentation-derived proteins cheaper, cleaner, and better than the real thing.
