Omidyar Network Executive Forum: Companies Honored For Social Impact (PHOTOS)

Last week, eBay founder Pierre Omidyar's Omidyar Network hosted its annual investees conference in Silicon Valley.

Known as the Omidyar Network Executive Forum, it's a three-day event that brings together social impact companies that Omidyar has invested in. From well-known non-profits like the Ashoka foundation to lesser-known ones like Ushahidi, these organizations all have one thing in common: They're changing society for the better.

The conference seeks to create a common platform for these companies. In a tough economic climate, many social impact organizations face similar problems: How to engage the media better? How to attract top talent? How to leverage social networks? The Omidyar Executive Forum aims to provide answers to these questions and create networks between like-minded companies.

At the end of the event, the Omidyar Network Award is presented to organizations that have created lasting partnerships and utilized their networks.

Here's a slideshow of the game-changing companies that were nominated this year:
