Luel
Y Combinator-backed marketplace connecting AI companies with contributors for rights-cleared, multimodal training data collection.
What is Luel?
Luel is a two-sided marketplace founded in 2025 and headquartered in San Francisco, part of the Y Combinator W26 cohort. The platform connects AI companies and enterprises seeking high-quality, rights-cleared training data with a global network of content contributors. Luel specializes in sourcing and licensing multimodal AI training data — including video, audio, and images — providing "to-spec" datasets that are compliant, audit-ready, and rights-cleared. AI teams submit specifications for the data they need (modality, scenarios, instructions, quality requirements), and Luel mobilizes its contributor network to collect, create, or provide the required content. The company emphasizes proper legal documentation, chain-of-title for all datasets, custom bespoke data collection campaigns, and a multi-stage QA process to meet enterprise standards.
Mission & values
Turn everyday words and actions into rights-cleared multimodal training data for frontier AI labs — bespoke collections plus an off-the-shelf marketplace.
Qualifications
Contributors earn money by providing media (video, audio, images) or participating in data collection campaigns. Luel matches vetted contributors to specific data-collection requests based on their profile and capabilities. The platform is designed for global participation, allowing contributors to monetize their content or actions by converting them into usable training data. Onboarding typically involves screening and quality verification processes. No specific degree is required, but the ability to produce high-quality media content and follow detailed specifications is essential. Projects vary in scope and compensation.
