Oculus VR is the first billion dollar company to come from Kickstarter

"Not even two years have passed since Oculus VR began a Kickstarter campaign to raise $250,000 for a better prototype of its virtual reality goggles known as Oculus Rift. It ended up raising $2.4 million.
Today the company sold to Facebook for about $2 billion.
By any measure, it looks like the most successful project ever to have raised money on the Kickstarter crowdfunding platform.
The nearest comparison is the Pebble smartwatch, which raised more than $10 million on the platform and later raised $15 million in a funding round led by Charles River, though its valuation is unknown. Ouya, a video game console, raised $8 million on Kickstarter, then also raised $15 million in a round led by Kleiner Perkins."
