Flypaper Studio, the creator of an easy-to-use Flash presentation editor, has raised $3.5 million in additional venture funding.

Through a graphical interface reminiscent of Microsoft Powerpoint, Flypaper users can create presentations that are more than simple slide shows, incorporating interactivity and a range of different media. Users can also share templates, images and other media with each other on the Flypaper site. The Phoenix, Ariz. company offers both a free application and a product called Flypaper Pro, which provides analytics tools, extra storage and other features for $195 per year; the free version has been downloaded “tens of thousands” of times, a spokesman says.

While Flypaper can be useful to anyone who wants to make a cool presentation (or brochure, or portfolio), chief executive Pat Sullivan says the company is focusing on sales and marketing customers. There is, after all, an obvious appeal to creating flashy promotional materials without much difficulty, and it gives the product an identity beyond “easy-to-use Flash editor,” which a number of companies offer. (Sprout, for example, has been praised for its fancy Flash widget editor.) That’s also the audience Flypaper is targeting with its pro product, since the analytics data can help salespeople see which parts of their presentations seem to be effective. Sullivan says the company has plans for an “enterprise” product this fall, which will include integration with customer relationship management (CRM) software and the ability to create a private company network for media-sharing.

One of the more disappointing aspects of Flypaper is that, as a downloadable application, it doesn’t work on Macs. Sullivan acknowledges that Mac compatibility has been one of the top customer requests. There aren’t any specific plans on the project roadmap, he says, but Flypaper Studio will probably address this problem by creating a version that works on any computer, using platforms like Adobe AIR or Microsoft Silverlight.

The funding is part of Flypaper Studios’ first round, which includes $3 million raised already. It comes from existing investors Sierra Ventures and SCF Arizona. The company will probably go out for a full second round next year, Sullivan says.
