I don't think that it's fair to say that software isn't technology. Facebook didn't create new hardware but the idea of the timeline was new.

But even if we look at hardware I don't think it's true. Bre's MakerBot industries did manage to sell MakerBots while it was a startup.

Arduino is created by a startup.

Pebble is a YCombinator startup. Technology like Arduino allowed Pebble to do their prototyping easier than was possible before. There are also a bunch of other Kickstarter projects that produce technology.

I do consider the Hackerspace ecosystem capable of creating new hardware.

A lot of new technology get's developed by repurposing existing technology. Arduino couldn't have been developed without the ability to buy cheap chips but Arduino is still new technology.
