As an interaction designer, I see tons of opportunities for great new products and solutions every day. Some of these solutions are easy to prototype. Eventually I will create a startup with the goal of social impact as well as business profit. Until then, I'd like to freelance invention.
I have a few products designed that I would like to prototype and test. After observing the product being used in the real world, I will more accurately determine if the product is viable and an appropriate solution. At that point I will find venture capital to fund mass production.
While I'm still creating and testing prototypes, I need funding.
How would you fund prototypes for new inventions?
Kickstarter crowd-funding seems plausible, but I won't have anything to offer my support "backers." All I will have is a prototype to run a test with. Generally people want a finished product in exchange for successfully funding the project.
