Company profile
researched Sep 2026Grably describes itself as a multi-modal human interaction data research lab that captures and models multi-signal human activity and decision-making, combining physical motion, physiological signals, gaze and vision, speech, intuition and contextual cues. The stated mission is to enable AI systems that understand what people are doing, how they decide and how they interact.
The company structures its work as a five-stage process: defining aspects of human activity, attention and decision-making that current AI models cannot capture; capturing synchronized multi-signal data (motion, gaze, voice, context, physiology) in both controlled and natural settings; structuring the data by aligning, annotating and validating each signal for cross-modality integrity; scaling to larger and more diverse populations and real-world environments; and maintaining living datasets that are continuously updated, re-verified and enriched.
Grably's advertised catalog includes multi-modal conversational and human interaction data (billions of sequential messages in more than 100 languages from over 500 million users, with views, forwards, replies, reactions and media files); diverse video data with meta information (9,000 years of video across more than 300 million clips covering computer use, gaming, spokesperson, DIY and negotiation categories); labeled sports event data covering football, soccer and other sports; and medical imaging, lab results and medical records spanning more than 45 million studies from 10 million patients. Each product lists a stated delivery time, ranging from two weeks for conversational data to 30 weeks for medical data, and the company also offers custom dataset design.
Business model
Grably assembles and sells proprietary multi-modal datasets to AI labs and research teams, with defined per-dataset delivery timelines and an option for custom dataset design for clients or collaborators with niche research goals.
Sale and delivery of proprietary and custom-built datasets to AI research customers.
Traction
Grably states that it holds 17 proprietary datasets covering more than 100 petabytes of data and more than 500 million participants, and says its datasets are used by AI labs and research teams. A third-party company data page lists Grably with 1-10 employees, including six employees across four departments.
▸Full profile — market position, technology, go-to-market, geography
Market position
Grably positions itself as a research lab focused on the "human layer" of intelligence, supplying multi-signal behavioral datasets rather than general-purpose web-scraped training corpora.
The company emphasizes synchronized capture across multiple simultaneous signal types (motion, gaze, voice, physiology, context) rather than single-modality data, scientific validation of cross-modality alignment, and continuously maintained "living" datasets.
Technology
The company collects synchronized multi-signal data across motion, gaze, voice, physiology and context, then aligns, annotates and validates each signal to maintain cross-modality integrity, and maintains datasets as continuously updated and re-verified assets. Its website is built with React and Framer Sites, and its reported stack includes Google Workspace, Google Tag Manager, Yandex.Metrika and GoDaddy hosting.
Go-to-market
Direct sales of catalog datasets with published delivery timelines via the company website, supplemented by bespoke dataset design engagements for research clients and collaborators.
AI labs and research teams developing models in multimodal learning, cognitive modeling, human-AI collaboration and decision-making analysis, as well as teams working on video generation, computer/browser use agents, and medical AI assistants.
Geography
United States; dataset offerings span more than 100 languages and global user-generated content.
