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, these six companies raised $250m. That prior start-up, an online industrial marketplace called NetworkOil and then Network International, was acquired by Liquidity Services. After earning an economics AB from Princeton, David’s career had started in “web 1.0” internet sector roles around general management, entrepreneurial corporate development and consultative technology sales.
