About
ParadeDB is a San Francisco-based database company — backed by Y Combinator (S23) with $14 million in total funding including a $12 million Series A in 2025 led by Craft Ventures with Y Combinator — providing developers and data engineering teams with a transactional Elasticsearch alternative built as a Postgres extension, enabling full-text search, vector search, and analytics directly within existing PostgreSQL databases without managing a separate Elasticsearch cluster. Launched in December 2023, ParadeDB has achieved 400,000+ deployments in 12 months and serves customers including Alibaba Cloud, Bilt Rewards, and Modern Treasury — making high-performance search and analytics available within ACID-compliant Postgres transactions that Elasticsearch cannot support.
