Why a mentor matters to a first-time founder
A good mentor can save you months by spotting mistakes they have already made, such as hiring too early or pricing too low. The relationship is informal: unlike an adviser or board member, a mentor normally gets no shares, fee or decision-making power. Mixing these roles up leads founders to give away equity for occasional advice or to expect a mentor to do work they never agreed to. Clear expectations protect both the advice and the relationship.
Examples of mentoring
You are about to hire two salespeople. On your monthly call, someone who built and sold a company like yours tells you to wait until you have closed 10 customers yourself and written down how each sale happened. They take no shares and they send no invoice. That person is your mentor. If you later ask them onto a formal advisory board, with equity and defined duties, that is a separate agreement you write down.
Common misunderstanding
People collect mentors as logos, or they give away equity for a coffee. Advice is not ownership. They also expect a mentor to do the work: introductions, hiring, the pitch. Some will. The role is still advice. If you need labour, hire, or make them a co-founder and vest it.
When to use it
Ask someone when you have a real question and you will act on the answer. A monthly call with no question is a performance. One honest mentor who has done the stage you are in will beat a list of five famous names.
