Datasaur
NLP labeling platform that grew into private-LLM development for regulated industries.
About
Datasaur started as a Y Combinator W20 data-labeling interface for NLP, founded in 2019 by Ivan Lee in Livermore, California, and has since repositioned as a private AI platform for regulated industries. The Data Studio product handles span labeling, text and document classification, OCR, bounding-box, audio, and conversational labeling, with AI-assisted pre-labeling, workforce management, and cross-validation to keep quality up. An LLM Labs product lets enterprises build private LLM applications that run inside their own infrastructure.
The company raised a $4M seed in August 2023 from Initialized Capital, Gold House Ventures, and TenOneTen, and it advertises SOC 2 and HIPAA-aligned deployments with VPC and on-premise options. That regulated-industry focus, keeping data on the customer's servers, is the differentiator against generic labeling tools. Pricing is subscription-based and enterprise-oriented.
