In 2017, achieving the goal of his search fund, David engaged with NovoNutrients: investing in it, pivoting it, and taking his current role as its CEO. NovoNutrients transforms waste, industrial CO2 into feed ingredients through industrial biotech – initially for the fast-growing aquaculture sector. For the prior dozen years, David was the sole manager of another fund, Aquacopia. That five-company, seed-stage portfolio had a thematic focus on aquaculture. The companies ranged from an aquafeed 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 $250M. That prior start-up, an online industrial marketplace called NetworkOil and then Network International, was acquired by Liquidity Services (NASDAQ: LQDT). After earning an economics A.B. from Princeton, David’s career had started in “web 1.0” internet sector roles around general management, entrepreneurial corporate development, and consultative technology sales.
