Los Angeles-based startup Moonvalley, a developer of AI-powered video creation tools, has secured an additional $43 million in venture capital funding, as disclosed in a recent SEC filing.

This filing, which lists 11 unnamed investors, comes approximately one week after Moonvalley unveiled its inaugural AI video-generating model, Marey. Previously, Moonvalley had raised $70 million in seed funding from notable backers, including General Catalyst, Khosla Ventures, and Bessemer Ventures.

According to a Moonvalley spokesperson, the filing “does not dictate the total funding number” and the actual figure will be formalized and announced in the coming weeks.

The video generator market has experienced rapid growth, with numerous vendors emerging in the space. Startups like Runway and Luma, as well as tech giants such as OpenAI and Google, are releasing models at a rapid pace, often with little differentiation between them.

Moonvalley’s Marey model, developed in collaboration with Asteria, a relatively new AI animation studio, offers customization options including fine-grained camera and motion controls. It can generate high-definition clips up to 30 seconds in length and is considered lower risk from a legal perspective, according to Moonvalley.

Many generative video startups train their models on public data, which can include copyrighted material. While these companies argue that fair-use doctrine protects their practices, rights owners have still filed complaints and cease and desist orders.

Moonvalley is working with partners to handle licensing arrangements and package videos into datasets that the company purchases. This approach is similar to Adobe’s, which procures video footage for training from creators through its Adobe Stock platform.

The emergence of video generators has raised concerns among artists and creators, who worry that these tools will disrupt the film and television industry. A 2024 study commissioned by the Animation Guild estimates that over 100,000 U.S.-based film, television, and animation jobs will be impacted by AI by 2026.

Moonvalley plans to address these concerns by allowing creators to request that their content be removed from its models, permitting customers to delete their data at any time, and offering an indemnity policy to protect users from copyright challenges.

Unlike some “unfiltered” video models, Moonvalley is committed to building guardrails around its creative tooling. Similar to OpenAI’s Sora, Moonvalley’s models will block certain content, such as NSFW phrases, and will not allow users to prompt them to generate videos of specific people or celebrities.
