Tuva Health, founded in 2020 in New York, USA, develops an open-source platform that cleans and organizes complex healthcare data such as insurance claims and electronic health records, making it easier for providers, payers, and pharmaceutical companies to analyze and use the information.

Luel is a human-data infrastructure company operating a rights-cleared data marketplace and collection engine for multimodal AI training data. Customers submit a dataset spec (modality, scenario, instructions, devices, QA rules); Luel scopes the project, recruits from a vetted global contributor network of 500K+ people across ~100 countries, runs multi-stage QA, and delivers licensed, audit-ready datasets (video, audio, images, screen recordings, sensor streams) within days, with new campaigns deployable in under 24 hours. Customers include generative AI labs, robotics companies, major social platforms, universities, hospitals, banks and ML research groups. Revenue comes from custom datasets, an off-the-shelf catalog, and marketplace listings. Luel is part of Y Combinator's Winter 2026 batch.

为模型实验室提供工程人才与训练数据

David AI, founded in 2023 in San Francisco, USA, creates and sells audio datasets for training large language models.

XDOF, founded in 2024 in Menlo Park, USA, builds data collection tools, data pipelines, and annotation systems for robot training data, serving AI labs and robotics companies. It addresses the bottleneck of insufficient physical manipulation data for general-purpose robot training.

Founded in 2024 and headquartered in New York, Mecka AI pays everyday workers such as baristas, cooks and mechanics to record themselves performing routine tasks using custom body sensors and iPhones, then collects and annotates this human motion and egocentric interaction data and sells it to robotics companies and AI labs training humanoid robots and other embodied models. It positions itself as a 'physical world data layer' addressing the shortage of real-world interaction data for embodied AI. Its four co-founders come from consumer fintech and crypto rather than robotics, having previously built Mentum (restaurant payments) and Utopia Labs (acquired by Coinbase).
