EnterpriseDB, the Postgres database company known as EDB, has acquired Altinity, a Berkeley, California, company that sells enterprise software, managed cloud services and round-the-clock support for the open-source ClickHouse analytics database. EDB announced the deal on November 5, 2026, from its base in Wilmington, Delaware.
The companies did not disclose the price or other terms. The acquisition has already been completed: Altinity chief executive Robert Hodges wrote on the company's blog the same day that Altinity is now the EDB Real-Time Analytics group, reporting directly to EDB chief executive Kevin Dallas.
Hodges said Altinity's customer contracts, service-level agreements, products and services are unchanged, that customers will keep working with the same engineering team, and that the whole management team is staying. Altinity's engineers will join EDB's Postgres contributors and maintainers on a single product roadmap, EDB said.
What Altinity built
ClickHouse is a column-oriented database for fast analytical queries over very large datasets. It began at Yandex before its use spread quickly, Altinity noted in 2020. Altinity, founded in 2017, built a business around helping companies deploy, operate and support it. Altinity says it is not affiliated with ClickHouse, Inc., which holds the ClickHouse trademark.
Its products include Altinity Stable Builds, certified long-term-support releases with three years of support and FIPS-compatible versions for regulated customers, and Altinity Antalya Builds, which add storage, authorization and data lake features. The Altinity Kubernetes Operator for ClickHouse, which Altinity says was the first Kubernetes operator for any analytic database, has been downloaded more than 108 million times from Docker Hub. Altinity.Cloud is a managed service that can also run inside customers' own cloud accounts, a setup Altinity says it was first to offer.
EDB named The Trade Desk, Tubi, Kong, AppsFlyer, ZoomInfo and PostHog among Altinity's customers, and said Altinity has helped hundreds of companies. Dallas described Altinity as the second-largest independent contributor to the ClickHouse code base.
“Having these two engines together in one multi-model data layer radically reduces costs for customers.”
Why EDB is buying
EDB calls itself a sovereign data and AI company. Its main product, EDB Postgres AI, is built on the Postgres database and aims to handle transactional, analytical and AI workloads in one system, with access rules enforced at the data layer. The company says it is the largest commercial contributor to open-source Postgres and its sales and support teams serve about 1,700 enterprise customers.
Adding ClickHouse gives EDB a dedicated engine for real-time analytics next to Postgres, which is built mainly for transactions. EDB argued that running both under one platform will lower costs for customers. It plans to introduce integrated enterprise ClickHouse capabilities in the fourth quarter of 2026, with a shared Apache Iceberg catalog and consistent access controls across the two databases on the roadmap.
The combined offering is meant to run wherever customers keep their data: in their own cloud accounts, in a developer cloud, on self-managed Kubernetes or OpenShift clusters, or on local hardware that is fully disconnected from outside networks. EDB said availability of each option will be detailed as the products launch.
What happens to customers
Hodges framed the deal as a way to secure Altinity's long-term commitments. Joining a larger company that backs open source, he wrote, gives Altinity the resources to meet its obligations to customers and the ClickHouse community over many years. He said the decision came down to shared values between the two leadership teams more than to technology or sales plans.
He also tied it to demand from AI. Companies building AI agents want software that can draw on large and fast-growing enterprise datasets, and many want to keep that data inside their own cloud accounts and data centers rather than handing it to outside providers. Hodges pointed to Kubernetes, ClickHouse and Apache Iceberg as the base for such systems and said Altinity's expertise in columnar storage and cloud operations complements EDB's work on database internals and transaction processing. He promised new products in the coming weeks.
The founders and the funding
In October 2020 it announced its first venture funding, $4 million from Accel, alongside the private beta of Altinity.Cloud on Amazon Web Services. At the time its services business had more than 50 clients, including Fortune 500 companies, and the release quoted Alexander Zaitsev as chief technology officer.
No further funding rounds have been confirmed, and neither company said how many people work at Altinity. The details of the deal reported here come from the two companies' own announcements.
