About
Great Expectations is a data quality and validation company founded in 2018 and headquartered in San Francisco, California. The company was founded by Abe Gong and James Campbell to commercialize the Great Expectations open-source Python framework, which they had originally built to solve data quality problems at their previous companies. The Great Expectations framework introduced the concept of treating data as code — defining expected data behaviors as declarative "expectations" in code, running them as part of CI/CD pipelines, and generating human-readable validation reports.\n\nGreat Expectations raised $40 million in funding from investors including Index Ventures and CRV. The open-source framework became one of the most widely adopted data quality tools, with millions of downloads and an active community of contributors. It supports a broad range of data sources including Pandas DataFrames, Spark, SQL databases, and all major cloud data warehouses, and integrates with orchestration tools like Airflow, Dagster, and Prefect. GX Cloud, the commercial SaaS product, adds a managed platform for sharing validation results, tracking data quality trends over time, setting up alert routing, and collaborating on data quality remediation across data teams.\n\nGreat Expectations's code-first approach and deep Pythonic integration make it the preferred data quality tool for data engineering teams with strong software engineering backgrounds. Its strength in the developer community, large library of community-contributed expectations and plugins, and integration with every major data platform give it broad reach across the data engineering ecosystem. The company has positioned GX Cloud as the collaboration and observability layer on top of the battle-tested open-source foundation.
