Mentors are of strategic importance to entrepreneurs. In accordance to the American Angel Investor Association, startups with mentor support are three times as likely to make it versus without a mentor. The most sought after mentor profile is an entrepreneur who has been in their situation and brought at least one company from zero to exit. A very different profile is interesting as well: subject matter experts, people with profound knowledge about the space the company the company is in. Consultants or enterprise managers are usually not so high on the hit list as many people think.
Good mentors make suggestions here and there. The best mentors never give advice. Instead they ask so many well articulated questions that the mentee comes up with the solution themself. Mentors may make connection to relevant people. The best mentors help the mentee to weave any connection they ever need themself. Mentors can help troubleshoot internal problems. The best mentors help the team solve the problem themselves.
