The Birth of Deasie: Data Governance for Language Model Applications

Is Your Enterprise Data Ready for Language Models?

Enter Deasie, a platform founded in 2023 with a singular purpose: to ensure that enterprises feed only relevant, high-quality, and safe data into their language models. The team recognized a critical issue – the inability of enterprises to identify the right set of documents for their AI applications. This realization led to the birth of Deasie.

What Does Deasie Do?

Deasie's core mission is to filter thousands of documents based on key data quality dimensions. These dimensions include relevance, timelines, consistency, and bias. Additionally, Deasie runs checks to identify sensitive information within the data, ensuring that enterprises maintain data compliance. Ultimately, Deasie delivers the optimal set of data to the target Generative AI (GenAI) application, enhancing the reliability and effectiveness of language models.

Leveraging a Proven Track Record

Deasie's founders come with a track record of success. Prior to founding Deasie, they built an ML data governance tool from scratch at McKinsey and deployed it with 11 Fortune 500 companies. This experience served as a crucial foundation for their current venture, highlighting the demand for robust data governance solutions in the industry.

Problem: Unstructured Data's Challenge in Language Model Applications

The Uncharted Territory of Unstructured Data

For the first time, enterprises are venturing into the realm of unstructured data. This includes documents, reports, emails, and a myriad of other text-based resources. Unstructured data has become a goldmine for Generative AI use cases, but it comes with unique challenges.

Critical Questions Left Unanswered

As enterprises delve into this unstructured data, they are confronted with critical questions that need answers:

Does this data contain sensitive information?

Is this the most relevant data for this problem?
Are there inconsistencies in the data that could skew my results?
These questions are paramount to ensuring the success and ethical usage of language models, but without the right tools, they remain unanswered.

Solution: Deasie's Data Governance Platform
