Odyssey, a world model artificial intelligence startup, has secured a $310 million Series B financing round, elevating its corporate valuation to $1.45 billion. The round was led by Natural Capital, with participation from Amazon, AMD Ventures, and GV. This latest capital injection brings the company total raised to $337 million since its founding in 2023. Founded by autonomous vehicle industry veterans, Odyssey is co-led by Chief Executive Officer Oliver Cameron and Chief Technology Officer Jeff Hawke. Cameron previously served as vice president of product at GM Cruise following the acquisition of his startup Voyage, while Hawke contributed engineering expertise to the United Kingdom-based autonomous firm Wayve. This deep background in self-driving technology directly informs Odyssey core technological focus. Operating within the rapidly evolving landscape of generative AI, Odyssey specializes in world models that move beyond traditional text and conversational large language models. The company develops systems that ingest physical world data and simulate it using accurate physics engines. To train these models, Odyssey employs a distinctive data collection methodology that mirrors geospatial mapping efforts but relies on personnel equipped with backpack-mounted cameras rather than autonomous vehicles. The resulting technology is currently deployed across robotics development, video game production, and advanced media generation, with the firm gaining particular recognition for its capacity to render rich, interactive video sequences from simple text prompts. Strategic infrastructure partnerships formed a central component of this financing milestone. Following the investment from Amazon, Odyssey has designated AWS as its primary cloud computing provider. The company will now focus on optimizing its world model architectures to operate efficiently on AWS Trainium semiconductor chips, establishing a scalable alternative to Nvidia dominant AI hardware ecosystem. The financing round attracted significant interest from the broader technology and venture capital community. Beyond institutional participants, Odyssey has secured backing from a prominent network of angel investors, including Google Jeff Dean, venture capitalist Elad Gil, Y Combinator president Garry Tan, Vercel founder Guillermo Rauch, and Cruise co-founder Kyle Vogt. This convergence of capital, strategic cloud infrastructure, and specialized AI talent positions Odyssey to accelerate the commercialization of physics-aware machine learning models across industrial and creative sectors.
