I'm about to launch a startup, do you do consulting for small companies with what I'd like to think is a big mission (likely similar to all startups lol)? In other words, is there some way to contact you and do you work with non-billion dollar startups if you find it worthwhile? Or is it more in line with 'read my books and call me when you raise your first million'?

Yes, I'd be happy to help you. Just drop me an email, and I can connect you to a variety of resources that might be stage appropriate for you.
