About
TEIEN is building Japan’s Data Foundry, an always on infrastructure that delivers trusted datasets seamlessly.
We are a collective of engineers and vetted domain experts who turn local data assets into production ready training and evaluation resources through rigorous QA and secure workflows.
Our name comes from teien, the Japanese word for garden, as a nod to Japanese craftsmanship: careful cultivation, precision, and quiet reliability.
What we do
We source, produce, and verify datasets across modalities, from text and images to audio and structured data.
We are developing a pipeline in which deliveries include clear specifications, transparent quality checks, and documentation you can audit, helping teams move from prototype to production with confidence.
