# DoubleDutch

> DoubleDutch was a mobile event technology company whose Developer Platform (DDDP) let customers and third-party developers build React Native extensions installable into any DoubleDutch event app. DoubleDutch was acquired by Cvent in 2019; www.doubledutch.me now redirects to Cvent's mobile event apps product. The developer surface (GitHub org, docs site, and official @doubledutch npm packages) remains published but is unmaintained. There is no public REST OpenAPI — the platform is a client-side extension SDK built on React Native and Firebase.
