Investment thesis
Coral Reef invests in early-stage companies that combine technology and creativity to build world-class businesses. It looks for creative new products, services and business models that are novel, scalable and ambitious. Evaluation criteria include a strong vision, exceptional and driven teams, positive and evolving market dynamics with defensible competitive advantage, and demonstrable traction such as revenue or user data. The firm will consider pre-revenue businesses if forecast assumptions are tested or supported, but generally avoids ventures requiring substantial R&D funding. It typically leads or takes the majority of a seed round or participates in a Series A, operating as a network of investors, founders and operational experts.
