I'm in a similar position--plenty of technical experience (~15K hours of programming, founded 2 startups and built the teams, sold 1), but I'm not quite sure what I want to build next. I've been offered early positions at a lot of startups, but nothing has really grabbed me yet.

If you think you have an awesome idea (eg, customer validation in a reasonably large market for something that is 4x better than existing solutions and yet not impossible to build), send me an email (joshalbrecht@gmail.com), especially if it's in an area that I have lots of experience in (finance, manufacturing, or machine learning)

Also, hit me up if you're in the Bay Area and need a technical cofounder on a mobile project.

I was on the Paper team, but besides iOS, I am very handy when it comes to backend or system administration tasks.

Just a heads up, but I opened the github link on your website and got a 404.

Weird, it works for me in Chrome/FF/Safari. What browser?
