“Like night and day”: How Auditzy made queries 33x faster by switching from Postgres to ClickHouse

Auditzy, a company founded in Mumbai in 2022, focuses on converting user interaction data from websites into actionable insights for various business teams, addressing both performance optimization and business impact. Initially, Auditzy's architecture using Postgres struggled with scalability and performance issues, such as query latency and complex maintenance tasks. In response, they transitioned to ClickHouse in 2023, following a successful proof of concept that demonstrated significant improvements in query speed, storage efficiency, and reduced technical debt. This shift allowed Auditzy to streamline operations and focus on new features, such as the Auditzy Copilot, which uses ClickHouse and LLMs to provide real-time, conversational analytics for users across an organization. The move to ClickHouse has not only enhanced the user experience and developer efficiency but also positioned Auditzy to innovate further in delivering dynamic and accessible analytics solutions.
