Felix William was drawn to venture capital at an early age. At just 17, he secured an internship at a venture capital firm in St. Louis. It was here that he first experienced the inner workings of the startup ecosystem. He dove into research, pitch evaluations, and investment strategy—all of which would influence his own path as a founder.
Though traditional academic pathways were available to him, Felix focused instead on hands-on learning. By immersing himself in the startup community and maintaining direct communication with founders and investors, he learned to identify opportunities and take calculated risks. This practical exposure formed the foundation for his business acumen and future leadership.
The Launch of Lagomaj Capital
In 2017, just before turning 19, Felix launched Lagomaj Capital, an early-stage venture capital firm based in St. Louis, Missouri. The idea came from a clear vision—he wanted to build a firm that did more than write checks. He believed in deep engagement with portfolio companies, offering strategic support that would help them scale.
Lagomaj Capital started modestly, but Felix’s approach quickly attracted attention. His focus was not only on capital deployment but also on building long-term relationships with founders. By actively participating in board discussions and infrastructure planning, he elevated the traditional VC model into a collaborative growth engine.
Investment Focus and Strategy
Lagomaj Capital concentrates on early-stage companies operating in technology, biotech, ag-tech, software, and transportation. Felix William’s strategy is centered on funding innovation that has the potential to create real-world impact—especially in sectors aligned with sustainable development and infrastructure.
Rather than taking a passive role, Felix ensures Lagomaj provides operational value. One standout example is the firm’s support for building R&D facilities in the ag-tech sector. These types of investments showcase his commitment to long-term ecosystem building. By aligning financial returns with innovation and development, he’s crafted a unique approach to venture capital.
Key Milestones and Investments
By the age of 22, Felix had already closed more than 30 deals, including investments in high-profile startups such as SpaceX, GigaIO, and Benson Hill. His firm expanded into Austin, Texas and Southern California to tap into new startup ecosystems. These expansions allowed Lagomaj to diversify its portfolio while deepening its network of founders and partners.
Felix’s most notable early success came when Agrible, a company backed by Lagomaj, was acquired by Nutrien for $63 million in 2018. This validated his early investment thesis and proved that strategic support pays off. By 2025, Lagomaj had scaled to over 45 investments, covering biotech, logistics, and software applications.
