Fivetran is a cloud data integration platform — it automatically syncs data from hundreds of SaaS applications, databases, event streams, and file sources into cloud data warehouses (Snowflake, Google BigQuery, Databricks, Amazon Redshift, Microsoft Fabric). Fivetran handles the difficult infrastructure work: managing connector APIs, schema changes, incremental syncs, and data quality — so data teams don't have to build and maintain custom ETL pipelines. Founded by George Fraser and Martin Chen in 2012 in Oakland, Fivetran grew from open-source beginnings into a $400M+ ARR enterprise business. Notable customers include Meta, Google, Salesforce, HubSpot, and thousands of mid-market and enterprise companies. The company competes with Airbyte (open-source), Matillion, and custom Python ETL pipelines. Fivetran raised over $730M from Andreessen Horowitz, General Catalyst, CEAS Investments, and D1 Capital Partners.
