I appreciate your desire to be helpful to startups. And I think instead of becoming a listed Mentor at 500 Startups, I'd reach out to companies who have graduated from 500 Startups who are "live in the wild" and in need of your expertise. Find the companies that you're really passionate about, and reach out to them directly and offer to help in any way you can.

You're likely to make a much greater impact on those companies this way and create meaningful reputation capital within the 500 Startups community and startup community in general.

For me personally, I think Clarity is a much more efficient and fun way to give back to other entrepreneurs. By answering questions and doing calls on Clarity with teams in need of your expertise, you're able to scale your impact far greater than pretty much any other way of helping.
