I would actually go further and say it's not just difficult, I imagine it would be near fatal unless you were a well established company walking in. We found fundraising to be an incredibly soul sucking process and without at least a firm grip and a solid plan for what you're doing you wouldn't make it far.

While not nearly as bad as fundraising itself, I would also caution people not to underestimate how much work a successful kickstarter is. A lot of work is required, and is continued to be required long after it has finished.
