What Deasy Labs does

Deasy Labs was acquired by Collibra in July 2025 (global leader in enterprise data governance). Deasy Labs provides metadata orchestration for AI workflows. Deasie's platform provides the best way for AI teams to create and embed high-quality, customized metadata into their AI workflows (e.g., RAG, Agentic frameworks). Our three founders (from Amazon, McKinsey/QuantumBlack & MIT) previously built an ML data governance tool from 0 to 1 within McKinsey, which we deployed with 11 Fortune 500 companies. We saw in early 2023 the ability to create high-quality metadata (without reliance on domain experts) would be a key factor in achieving the accuracy & speed in GenAI applications required for production. Our investors include General Catalyst, Y Combinator, RTP Global and world experts in enterprise data. Website:

Metadata for GenAI workflows

What is your company going to make? Please describe your product and what it does or will do.

We build a metadata orchestration platform that helps AI teams create and embed high-quality, customized metadata into GenAI workflows, like retrieval-augmented generation and agentic frameworks. This metadata improves accuracy and speed by eliminating dependence on domain experts for labeling and annotation.

Where do you live now, and where would the company be based after YC?

We live in New York City, NY, and the company is based here. After YC, we plan to keep Deasy Labs in NYC.

Explain your decision regarding location.

We are based in New York City because it allows us to tap into top enterprise clients and talent. It's also where the three of us reside and have built relationships. Staying local keeps us focused and efficient.
