Clusterity is a PostgreSQL consulting and training company that also builds database tools. Its services include an annual training program, half-day and full-day workshops on migration safety, reading query plans and reviewing AI-generated SQL. It also offers SQL Labs, sandboxes for practising on production-scale data, and publishes the open-source tools dryrun, RegreSQL and Fixturize.

The customers are engineering teams working with PostgreSQL. The annual program starts at €12,000 per year for a team of up to eight engineers, workshops cost €2,500 (half-day) or €4,000 (full-day), and SQL Labs is sold as a solo plan at €495 per year or a team plan from €1,990 per year. Prices are quoted ex. VAT in euros. Revenue comes mainly from training and consulting, with the product plans as a smaller line.
