Fivetran

Founded in 2012 by George Fraser and Taylor Brown out of Y Combinator, Fivetran builds automated data-movement pipelines that extract data from hundreds of source systems (SaaS applications, databases, event streams) and load it into cloud data warehouses and lakehouses such as Snowflake, Databricks, BigQuery, and Redshift. The company markets its connectors as zero-maintenance: schemas adapt automatically as source systems change, removing the custom ETL engineering work that data teams historically built and maintained by hand. Fivetran expanded into enterprise-grade data replication with its 2021 acquisition of HVR, broadening its base beyond SaaS-to-warehouse syncing into high-volume database replication for large enterprises. In 2026, Fivetran completed an all-stock merger with dbt Labs, the maker of the open-source dbt transformation framework, combining Fivetran's data-movement layer with dbt's data-transformation and semantic-modeling layer under one roof, with the explicit goal of building a governed data foundation for enterprise AI agents. The combined company describes itself as serving more than 100,000 data teams, and continues to operate under the working name "Fivetran + dbt Labs" post-merger. Fivetran remains a private company; there is no public trading venue for its stock, and secondary transactions occur only through private funding rounds and pre-IPO share sales.
