Great Expectations

Great Expectations is a pioneering data quality platform established with the objective of helping data teams achieve confidence in their data, regardless of the challenges they face. Founded in 2017 as a side project by Abe Gong and James Campbell, the company quickly gained traction within the data community due to its innovative approach. The primary offering, GX Cloud, serves as an end-to-end solution for managing the entire data quality process, providing users with a seamless experience while leveraging the power of the world's most widely adopted data quality framework, GX Core.

The core of Great Expectations revolves around the concept of 'Expectations', which are verifiable assertions about the data. These Expectations empower organizations to develop clear and expressive data quality tests, enabling both technical and non-technical stakeholders to engage collaboratively. Moreover, the framework supports a comprehensive set of data quality dimensions, including schema, freshness, volume, and more, to ensure reliable data management.
