In 2017, David became CEO of NovoNutrients. He invested in it, pivoted it, and led it through the IndieBio accelerator. NovoNutrients transforms CO2 emissions into food and feed alternative protein ingredients, through natural microbes and industrial biotech. Since 2004, David launched and managed the Aquacopia fund, a five-company, seed-stage portfolio focused on aquaculture and nutrition. The companies ranged from a protein ingredient manufacturer to a distributor and marketer of sustainable seafood. The fund also led investments into Open Blue, InnovaSea, and Futuna. Including a prior start-up that David co-founded, those six companies raised $250 million. That prior start-up, an online industrial marketplace called NetworkOil and then Network International, was acquired by Liquidity Services (NASDAQ: LQDT). David’s career had started in “web 1.0”, doing general management, entrepreneurial corporate development, and consultative business development, after an economics A.B. from Princeton.
