Perceptron (Perceptron Network) is a ~2024-founded decentralized AI-data-infrastructure startup with a UK/UAE/Israel team. It condenses global data collection into a single contributor mesh, letting AI companies commission specific, human-verified datasets on-demand via its data-questing platform, delivered in days by ~800K nodes and 300K+ daily contributors across 150+ countries at ~90% lower cost than centralized data vendors. It merged with the 700K-node BlockMesh network in June 2025 to form an end-to-end DePIN data pipeline with token incentives.

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).

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.

AfterQuery, founded in 2024 in San Francisco, USA, is an applied research company that provides expert datasets and reinforcement learning training environments for frontier AI models.

Kaiyu Data (Kai望数据), founded in 2022 in Beijing, builds an AI data automation platform and provides one-stop AI data solutions for automakers, autonomous driving companies, and other cross-industry enterprises.
