I think of the proposition as an intro to a PARTNERSHIP.
I posted above that I'm willing to match the offer. I don't think of this as an "investment" so much as me trying to kick start a relationship where I'm a cofounder.
As such, I'm interested specifically in ideas where I believe I can provide value that the other cofounder doesn't, so we both benefit. I expect it to be an ongoing pursuit where I continue to work on the company.
Buying half a company for 5k and then putting in 3k of advertising only to walk away would be the wrong move on my part and that's not the intention I have going into any transaction that may result from this.
