Stripes Group and Accel Partners have made a $61 million growth equity investment in Pond5, an online marketplace for video footage and stock media. The fresh funds will be used to fuel global growth, hiring and product development. Artists from around the world use Pond5 to upload video clips and other media, including music, photos and special effects. Those creating media projects, like films, mobile applications and video games, can then buy the royalty-free content for their own use. Pond5's collection currently boasts more than 15 million media clips sourced from 30,000 artists in 127 countries; its 2.7 million videos compose the largest royalty-free video collection online. The company has been cash-flow positive since its founding in 2006 and doubles sales annually.
