That sounds like an naive argument to me! If your business wants to get funding for something, you better damn well have a good plan before you approach anybody. Or you'll be laughed at. Hell, try getting any money - what so ever - of third parties these days. Even if your portfolio looks like a throbbing totem pole...
It's all too easy assuming people will invest money on your good name or your previous endeavours. But that doesn't tell much about your current project and its potential. I think that's why Kickstart works for so many initiatives. People expect presents and signed bits in return. And that's fine considering the average amount of money pledged.
The problem with Kickstart is that it's just plain stupid to "invest" over €500. Sentiments and emotions set aside, of course. Because I think they are valid reasons of their own. Let's say the total project requires €500.000. And I put in €15.000. I would be expecting a piece of the revenues or the company at the very least. That's 3% of the total investment! For a dinner with the designers, two signed T-shirts, an old hockey puck and two sketches, I can get better returns than that.
My blunt point (as usual) is... Kickstart is just for fans who are emotionally attached and can go without a few bucks. It has a nice ring to it: Pledging money. And "investing in a project", "making stuff happen"... But really though, who'd invest in my company that actually has a steady revenue for the past couple of years. Other than my boyfriend and my dad of course? ... Do I hear €10.000? Do I hear 11.000? No? €500 then! I throw in this signed T-shirt! No? Aaaw!!
... Now, Two Guys, take my €1000, ja! :)
