San Francisco CA open-source data quality framework; raised $40M+; GX Cloud adds hosted monitoring and collaboration on top of the widely-used OSS library.
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.
San Francisco CA semantic layer and headless BI platform; raised $100M+; API-first data access layer that sits between warehouses and any BI or AI consumer.
Cube is a semantic layer and headless business intelligence platform founded in 2019 and headquartered in San Francisco, California. The company was founded by Artyom Keydunov and Pavel Tiunov to solve the problem of metric proliferation in data-driven organizations: when every BI tool, internal application, and data consumer defines its own metrics independently, companies end up with different answers to the same business question depending on where they look. Cube provides a single semantic layer — a governed data model layer — that defines all business metrics and dimensions once, then serves them consistently to any downstream consumer via REST, GraphQL, or SQL APIs.\n\nCube raised $100 million across multiple funding rounds from investors including Bain Capital Ventures, Decibel Partners, and 468 Capital. Its platform is built on an open-source core (Cube.js) with hundreds of thousands of community users and deployments. The commercial Cube Cloud product adds managed infrastructure, a development environment, testing tools, query caching for performance optimization, and access controls. Cube's API-first, headless architecture allows it to serve metrics to traditional BI tools, embedded analytics applications, internal data apps, and increasingly AI assistants and large language model (LLM)-powered analytics tools.\n\nCube's caching and pre-aggregation engine is a significant technical capability: it automatically builds materialized aggregates from frequently run queries and serves them from a high-performance cache layer, dramatically reducing warehouse query latency and costs for dashboards and embedded analytics applications. This performance layer makes Cube a practical choice for public-facing embedded analytics where end users expect sub-second response times that direct warehouse queries cannot reliably deliver.
