Custom Software Development

ExtensionEngine has deeps roots as an outsourced software development firm. We have 150+ developers and QA located in the talent-rich Croatian cities of Split and Zagreb. Our UX team and senior project managers and principals are based in Cambridge, MA, USA.

Though our focus is now primarily on Custom Learning Experiences, we provide ongoing outsourced software development to a number of long term clients. We selectively take on new projects if they are interesting, technically challenging and we have a chance to collaborate with world-class companies. Contact us if you are interested in learning more.
