>"What are examples of successful crowdfunded companies?"

I can talk about successful crowdfunded products, including products made by companies.

To give one example to start with, Formlabs has used crowdfunding to help generate money to manufacture their 3D printers:

I'd suggest it comes down to experience. With experience in crowdfunding you can spot the campaigns that are likely to succeed, and which ones are likely to fail. The main problem I see is when campaigns are too ambitious based on the background of the people involved. For example, high volume manufacturing in China without prior experience of working with Chinese manufacturing companies.

In formlab's case they had a 1.8MUSD seed round prior to the crowdfunding. They raised ~3MUSD from crowdfunding.

This probably helped give them some runway to put together a series A. However they still raised an additional 50MUSD.

So, I don't think they're a great example of a company bootstrapping from crowdfunding. It's more of a traditional play, with some validation (and some runway) from crowdfunding.

How about Pebble? They did start being funded by Y Combinator and angels but got most of their funding from Kickstarter https://en.wikipedia.org/wiki/Pebble_(watch)#History

But now they got bought out by FitBit after going too much in debt (?).

Occulus. That one ended well for the founders.

Bought out by Facebook -- which is not the norm of most crowdfunded companies. In my personal belief, the crowdfunding model as it exists now is not a form of investment that will scale well. When a kickstarter company fails, it's not liable to all the people it took money from unless by fraudulent circumstances. What I believe will be more viable is a crowdsourced capital fund where an executive acts as a trustee representative and makes investing decisions for us.
