Investment thesis

Rockstart backs ambitious, purpose-driven founders working toward a regenerative and sustainable future, focusing on three domains: Energy, AgriFood, and Emerging Technology. It invests from pre-seed through Series B and combines capital with domain-focused, mentor-driven support packages, market introductions, and connections to co-investors. Rather than lecture-style programming, it matches founders with relevant experts and mentors on their key challenges. A global community of mentors, investors, and corporate partners drives commercial partnerships and investor exposure, with corporate initiatives such as Ørsted Propel and the New Energy Challenge helping founders reach markets and leading companies faster.
