Ask HN: Why is there no Kickstarter for startups yet?

Hey there,

I've been working on https://buymeadomain.com for over a month now. I've been soft-launching on various forums & subs and gaining a lot of feedback along the way. One such feedback was to turn this into a "Kickstarter for founders who are in napkin-sketch stage".

I searched for Kickstarter for startups but it seems no one has cared to make something like that yet! Why is it so? Are there any complications?

Let me know.
