Gnostic: Sadly the almost all of game kickstarters cannot get enough funds to avoid outside funds completely. Not every crowdfunding is StarCitizen.
Niggles: MY understanding of KS were funds needed to start and complete the goal. Im wondering how many actual devs have completed games without going third party sourcing or crawling to early access?.
There are a few, like the devs of Forced and Shovel knight, at great sacrifice and personal cost.

They rised 65K on kickstarter and still need to take a 200K bank loan. The rest of the struggles can be easily seen in the funny story picture

Shovel Knight Devs got 300K when they need 1.44 M under normal condition because not only for salary, but health insurance rent, electricity, water, food/snacks, conventions, computer and other equipment, software licenses, lawyer fees, taxes, development kit expenses etc
One of the team take no pay and the rest have half pay.
They even plan to cram 2 years development time into one year, but end up 5 month without pay because after one year they cannot release a satisfactory build.
