Most people start mentor search backwards. They look for fame, then hope expertise is attached. The useful order is the opposite: name the outcome you need in the next 90 days, then find someone who has shipped that outcome recently. A specialist with 40 honest reviews will usually beat a generalist with a million impressions.
Fit shows up in three places. Domain — have they done the work in your category, not adjacent theatre? Stage — a Series B operator and a first-time freelancer give different advice, both valuable, rarely interchangeable. Working style — some mentors diagnose fast and send you away with homework; others sit with the mess. Read bios for verbs, not adjectives.
Price is a signal, not a personality test. Extremely cheap sessions often mean the mentor cannot afford to prepare. Extremely expensive sessions are fine if the scope is explicit. What you want is a published rate, a clear session length, and a profile that states who they will not take on. Ambiguity is more expensive than a higher hourly number.
Before you book, write a one-paragraph brief: current situation, decision on the table, what you already tried. If a mentor cannot respond to that brief in a useful way — even in a short public bio — keep walking. Prepared learners get better hours; vague learners get motivational speeches.
