How Community Building Helped Photojojo Find Success The online forum and store is devoted to do-it-yourself photography tools and techniques, but the main goal is creating long-term relationships.

Photojojo, an online forum and store devoted to do-it-yourself photography tools and techniques, makes community-building look like a snap. "Our growth has been fueled entirely by word-of-mouth," says Amit Gupta, who started the company six years ago to serve an emerging generation of photo buffs who want to "customize mass-produced objects" such as iPhones and "make their own stuff."

Photojojo attracts between 1.1 million and 1.5 million unique visitors every month and has a registered community of more than 1 million. (The company does not disclose revenue figures.) Site visitors are encouraged to share ideas and tips, post old and favorite photos and learn about the latest tools and techniques through tutorials. The site also sells unusual and hard-to-find gear and accessories.

"Photojojo's goal is to make photography more fun for everyone," Gupta says.
