Sigma, the layer to build and scale your analytics, apps, and agents, announced it has joined ClickHouse’s House Mates partner program as a founding Accelerate-tier member. The partnership, launched at ClickHouse Open House in San Francisco, connects Sigma’s warehouse-native AI Apps and agentic analytics platform with ClickHouse’s high-performance real-time data infrastructure, giving enterprises a governed path from live data to confident decisions.

House Mates is ClickHouse’s partner community and program, curated to bring together the platforms enterprises trust most to build on top of ClickHouse. Sigma joins as a founding cohort member at the “Accelerate” tier, the program’s higher-level designation for technology partners with deep integration and joint go-to-market commitment.

For joint customers, Sigma connects directly to ClickHouse and executes queries live against the source, with no extracts and no copies, so business teams can work with real-time data through a familiar spreadsheet interface while inheriting the access controls enterprise IT already has in place.

“We built House Mates to bring together the partners our customers depend on most,” said Aaron Katz, Co-Founder and CEO of ClickHouse. “Sigma stood out from the start. Their warehouse native architecture keeps queries running at ClickHouse speed and puts that performance directly in the hands of business users. That’s the kind of partnership that creates real value for our joint customers, and exactly why Sigma is part of our founding cohort.”

“ClickHouse is one of the fastest-growing databases in the market, and our customers are building on it because it delivers disruptive cost-performance,” said Sigma CEO Mike Palmer. “Entering the House Mates partner program is our commitment to delivering the best runtime layer on top of ClickHouse.”

Together, Sigma and ClickHouse deliver a full analytics path from raw data to governed business action: ClickHouse provides the real-time, high-throughput data layer, and Sigma provides the governed workspace where analysts, operators, and executives work with that data through a spreadsheet-like interface, SQL, Python, or natural language without ever moving data out of the warehouse. Joint customers benefit from live query performance, inherited access controls, and a single platform where dashboards, analyses, AI applications, and agentic workflows all operate on the same governed data.
