Ownership for business cofounder
I'm primarily a developer/engineer. My designer and I have been working on our project for a while (>2 year) while we've had other jobs. We're both perfectionists so we took our time until the thing was perfect (did user surveys, ran previous versions, did customer surveys, rinse and repeat etc)
I spoke with a couple of investors in the interim, but I got the sense they seemed leery until we could show there were actual people using the darn thing at least. Making products is my forte anyway, so I figured I'd work on it. So now we're a couple of weeks away from letting friends and family use it. It is time again to at least get back on investors' radars but I can only focus on so many things at a time: write code, fix bugs, work on my real job etc.
Meanwhile my previous manager had been asking to become CEO. He's a pretty good salesguy and has been able to get some good meetings etc with investors and prospective customers in the last month or so.
My question is what is the proper ownership ratio to offer the guy?
