Interactive cloud-based presentation service Prezi has announce it just passed five million registered users. The impressive milestone has been reached in 2 years, according to a post on the company’s blog.

To mark the occasion, the company developed the Prezi (of course) below which shows its progress highlighting its most significant moments along the way.

The company has a pretty unique background. The concept was born in Budapest, Hungary, in 2007 when architect and artist Adam Somlai-Fischer, who had long tinkered with zooming presentions, built the prototype Prezi product on the advice of Budapest University of Technology professor Peter Halacsy.

Somali-Fischer and Halacsy, who is now Head of Product, then recruited Peter Arvai as CEO, and the trio build the product into a company. Prezi was launched in April 2009, a year that proved to eventful seeing investment from TED Conferences and Sunstone Capital and the opening of a San Francisco office in November.
