Luel

Luel is a two-sided marketplace and multi-modal data lab for AI training data, connecting companies that need high-quality, rights-cleared datasets with verified contributors who supply and license on-demand video, audio, and image data. Contributors can earn money by submitting media from their own devices (for example, footage from their camera roll) or by completing requested data tasks, while buyers purchase premium, curated, rights-cleared multimodal datasets from the Luel catalog. Positioned as "the frontier of data," Luel powers the foundations of machine perception through a proprietary, continuous data engine. The company is backed by Y Combinator, General Catalyst, and Lightspeed Venture Partners. Luel does not currently publish a public API, SDK, or developer documentation surface.

Luel is profiled on the APIs.io network. Tagged areas include Company, AI, Machine Learning, Training Data, and Data Marketplace.

Luel’s developer surface includes signup flow, engineering blog, support, and 6 more developer resources.
