I guess I should have been more clear. From my post, I'm looking for "someone extraordinarily entrepreneurial to be in the founding team of a company, with equity and responsibilities to match."
I am fully prepared to give a way a very large chunk of my company. Will it be 50%? I don't know. I've invested a lot into this, and other people have some equity now too. But I 100% understand the value of a tech co-founder, and am not looking to be stingy with equity. I know I can't make it succeed on my own.
