Luma AI
A California AI lab, headquartered in Redwood City by its own account, that builds video and image generation models. It is best known for Dream Machine, its text-to-video app released publicly on 12 June 2024, and for the Ray family of video models that now power its products.
Luma was founded in 2021 by Amit Jain (CEO) and Alex Yu (CTO), with Jiaming Song as chief scientist. Its site says it has raised more than $1.1 billion across five rounds, the latest a $900 million Series C in November 2025 led by Saudi Arabia's HUMAIN with AMD Ventures, Andreessen Horowitz, Amplify Partners and Matrix Partners; press reported a valuation of about $4 billion, and the round came with access to HUMAIN's 2-gigawatt supercluster. Before Dream Machine it had made Genie, a 3D model generator.
Its product line also includes the UNI image and multimodal model, Luma Agents (launched March 2026), an API, Luma Enterprise, and an Open Physical AI Lab for robotics research (June 2026). Dream Machine drew criticism in June 2024 when a promotional trailer resembled Disney and Pixar's Monsters, Inc., and critics noted its training data is undisclosed.
