Every year, the editors of Technology Review pick 25 public and 25 private companies judged to be the most innovative out there.
These companies use new technologies to set the agenda in their industries, or to invent new industries from scratch. The last TR50 included firms like Apple, Complete Genomics, SpaceX, and Square.
The list is published each March, and we’re assembling the 2012 list now.
Take a look at the 2011 list, and tell us in the comments below about any new companies you believe we should consider for inclusion. Just as importantly, tell us which companies should no longer be on the TR50 list, either because they sat on their laurels, or their technology failed to deliver on its promise.
