Superconductive

Superconductive Inc. is the company behind Great Expectations (GX), an open-source data quality framework used to validate, document, and profile data across modern data stacks. Teams declare "Expectations" — assertions about how data should behave — and GX Core, the Apache-2.0 Python library that is the engine of the platform, tests batches of data against them, generates human-readable Data Docs, and integrates with orchestration and cloud data tools. Superconductive is backed by Index Ventures. GX is distributed primarily as a Python package rather than a hosted REST API; the managed GX Cloud SaaS offering has been wound down, leaving the open-source library as the supported surface.

Superconductive is profiled on the APIs.io network. Tagged areas include Company, Data, Data Quality, Data Validation, and Data Testing.

Superconductive’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, changelog, and 12 more developer resources.
