Uber is buying up robotics departments and pushing into autonomous vehicles. They're definitely furthering the technological front. Also, I think you'll find plenty of criticism of Uber around here, it's not one of the most well-regarded companies.
The first privately funded, liquid-fueled rocket (Falcon 1) to reach orbit (28 September 2008)
The first privately funded company to successfully launch (by Falcon 9) Orbit and recover a spacecraft (Dragon) (9 December 2010)
The first private company to send a spacecraft (Dragon) to the International Space Station (25 May 2012)
The first private company to send a satellite into geosynchronous orbit
As an example, Linux wasn't the first UNIX-like kernel or the even the first free UNIX-like kernel, but it (with GNU) was the first free UNIX-like kernel to bring a UNIX-like kernel to the mainstream PC world and span the entire vertical range of computing scale from microcontrollers to TOP500 supercomputers. I'd call that expanding the technological front.

I booked a ride on Uber just the other day.

If we're setting the goal post for "furthering the technological front" at "helping all of humanity" then technology is at a standstill and the Internet is a failure. After all, fewer than 50% of the world uses the Internet.
