ClickHouse Inc. has secured $350 million in a Series C funding round led by Khosla Ventures, bringing its total funding to over $650 million.
ClickHouse's database, based on a columnar architecture, optimizes data retrieval by storing columns adjacent to each other for faster query processing.
The database includes performance optimizations like vectorized query execution, range query simplification, and the ability to handle massive scales of data.
ClickHouse plans to use the new capital to accelerate product development and expand its global presence, serving over 2,000 customers including major tech firms like Sony Corp. and Anthropic PBC.
