From Bulgaria to Global Networks: The Entrepreneurial Path of Nathaniel Stefanov

Nathaniel Stefanov, Founder of GRVTY

Nathaniel Stefanov is an entrepreneur from Bulgaria. He has built organizations that connect startups, investors, and innovators. He co-founded Gravity, a company focused on fan engagement in sports. His mission is to empower athletes to own their relationship with fans and monetize their name, image, and likeness.

He grew up in post-socialist Bulgaria. That experience shaped his support for capitalism. He saw inefficiencies in how the state managed resources. He believes private initiative drives better outcomes, innovation, and accountability. For him, capitalism is not only an economic system but also a culture of responsibility and action.

Gravity is built on that principle. Today, most sponsorships in sports go to the top one percent of athletes and clubs. Gravity is building tools for the long tail, where athletes struggle to find visibility and support. The company focuses on underserved groups such as young athletes, women, and athletes of color. It also provides financial education so athletes understand how to manage and grow what they earn.

Nathaniel also sees his role as a connector. He has supported more than 100 startups and sits on multiple boards. He offers Liberty Ventures members access to networks in Europe, the UK, and the US. He can connect investors to companies, and companies to capital. His strongest domains are sports, life sciences, and research-based innovation. He values feedback and believes that relationships are the foundation of sustainable business.

When asked what he seeks from others, he points to knowledge and relationships. He wants to learn where trends are heading and to build trust with peers. For him, good business outcomes follow strong connections.

Gravity itself targets a $1 trillion opportunity at the intersection of sports, gaming, social impact, and content. Nathaniel sees it as both a business and a passion. The name reflects that. Gravity comes from the image of sports as a universe, with many planets—football, basketball, tennis—held together by a central force. The brand dropped vowels to stand out in a modern market, and it carries the meaning of gravitas, or value and virtue.

Nathaniel’s work blends entrepreneurship, innovation, and social purpose. He believes business leaders should use capitalism to empower people, not only to generate profit.
