How Rapid River came to be.

  • 2010-2011

    Rapid River's founders, Nick and Calum, work together as expatriate software developers at the Malaysian back office of an international financial derivatives trading firm. Both move on to different companies, but remain friends.

  • 2013

    Rapid River Software, Inc.

    After a couple of years back in the USA as part of the San Francisco startup scene, Nick hangs out a shingle as a DevOps consultant. Nick names his company after a beautiful whitewater river in Maine where he learned to kayak when he was a teenager.

  • October 2014

    One Becomes Two

    Apparently people need good software developers. (Who knew?!) Thanks to GitHub, PivotalTracker, and Slack - tools that allow developers to collaborate seamlessly around the globe - Calum is able to quit his day job and work full-time with Nick for Rapid River's US-based clientele.

  • May 2015

    Rapid River Software Sdn Bhd

    Now with four full-time remote developers, Nick and Calum are still unable to keep up with the demand for Rapid River's services. They decide to incorporate in Malaysia as an MSC status company in order to tap into the enormous pool of Malaysian and expatriate developers around Kuala Lupmur.

  • 2016

    A Real (Full) Office

    With five developers in Kuala Lumpur and nine others worldwide, Rapid River opens its Kuala Lumpur headquarters on the 25th floor of a shiny new grade A office building in Bangsar South. We remain true to our roots as a developer-centric company whose motto is: "We get things done."
