Datost is a proactive AI data analyst that operates inside team communication tools like Slack. It maintains a semantic layer of business definitions so it can understand context-specific terminology before generating SQL, and it connects to data sources including Postgres, MySQL, BigQuery, Snowflake, and Databricks, as well as tools like Datadog, Sentry, and PostHog via MCP. The company was founded by Maceo Cardinale Kwik, who built Datost while at Traba and reached 80% adoption there, and Jason Wang, who previously managed payment infrastructure at Traba. Datost is based in San Francisco and is part of Y Combinator's Spring 2026 batch.
