3D3R Software Studio was a web-focused software development and consulting firm founded in 2007 by Ohad Eder-Pressman, an Israeli/American developer committed to writing software grounded in engineering and inspired by design. As an evolved firm, 3D3R Software Studio remained faithful to this ethos of rigorous coding and artistic innovation. By involving our clients in the design process, our engineers combined expertise and enthusiasm to deliver a superior product and a better experience.

On November 2011 3D3R was acquired by Chegg Inc where among other things the team has lead the development of Chegg's world-class HTML5 eTextBook Reader.
