How ADA Built 500+ Data Connectors for a Leading Data Integration Platform
500+ Connectors | Custom Development | Global Platform
Fivetran needed connectors for sources without standard integrations, regional platforms specific to Asian markets, legacy systems that predated modern APIs, and niche applications with proprietary formats. Enterprise deals were stalling because customers couldn’t connect the sources they needed.
Building connectors at scale required diverse API expertise — REST, SOAP, GraphQL, custom protocols, plus regional ecosystem knowledge that US-based teams didn’t have.
ADA became an extension of Fivetran’s engineering capacity, building custom connectors using a hybrid Clojure and Java pipeline. Every connector met production-grade standards for reliability and security.
Over two years, ADA delivered 250 connectors covering regional platforms, legacy systems, and niche applications, unlocking enterprise deals that had previously been blocked.
