Critical Frontier
Thomas Tull's Critical Frontier, a single-family office managing over $25B, invests in AI, climate tech, real estate, and private credit.
Critical Frontier
Thomas Tull established Critical Frontier after stepping down as CEO of Legendary Entertainment, which he built into a major film production and finance company. The firm manages capital generated from Tull's sale of Legendary to Wanda Group and subsequent ventures, operating as a single-family office based in New York. The investment strategy spans private equity, venture capital, real estate, and credit. Critical Frontier leads or co-leads direct investments in artificial intelligence, enterprise software, and climate technology companies. Notable holdings include positions in Anduril Industries, a defense technology company, and Stripe, the payments infrastructure firm. The firm also develops real estate through its affiliate, and participates in private credit deals. Critical Frontier is believed to manage over $25 billion in assets, though the firm does not publicly disclose AUM. The team includes former executives from private equity, technology, and media. Tull also runs the Tull Family Foundation, which focuses on education and veteran affairs. In September 2024, Critical Frontier was reported to have led a $200 million financing round for a robotics company (per Bloomberg, September 2024). A structural differentiator is the firm's ability to source proprietary deals through Tull's deep relationships in entertainment, technology, and government contracting. This network allows Critical Frontier to access opportunities often closed to traditional institutional capital, giving the firm a long-term, patient capital posture.
