This is an excellent topic and thank you for this nice article providing tips for choosing the right Entrepreneurial Mentor. I have one question. You have mentioned:
"Angel investors are good candidates to become mentors. They like to relive the glory days vicariously through investments and the entrepreneurs driving the companies. They're interested also in helping you succeed."
But I feel that the investor can be a good mentor in very rare occasions. Most of the time, an investor would have interest in the success of the start-up. Hence more than mentoring, it could be providing instructions, which would prevent the entrepreneur to be able to think more independently...instead of grooming the entrepreneur, it could be more of "spoon-feeding" isn't it?
Thanks, Sanjib. You express a valid concern however, in my experience, angel investors are not seeking a 'quick hit' and are more interested in helping the process of building a successful company. The entrepreneur needs to be watchful that philosophies are aligned with the angel.
