A founder sat opposite me last month and said: 'I've been told I need a coach. I've been told I need a mentor. Someone at my board said I need an advisor. I don't know what the difference is, and I don't have time to hire three people.'
That's the right instinct. The market has confused these three words for so long that most leaders can't tell them apart. Which is a problem, because they do very different things — and hiring the wrong one for your specific moment will cost you six months.
Here's how to tell them apart, and how to tell which one you actually need.
The three roles, honestly defined
A coach helps you find your own answer.
Not because coaching is holier than telling. Because your answer, when you find it yourself, is the one you'll actually execute. A trained coach doesn't hand you the solution — they ask the questions that surface the solution you already know but haven't articulated. They notice the patterns you're running. They hold space for the thinking you don't have time for anywhere else.
Good coaching feels slow at first. Then, at some point, it feels like the fastest thing you've ever done. Because you stop making the same mistake for the fourth time.
A mentor shares experience.
Where a coach asks questions, a mentor tells you what happened when they were in your seat. They pattern-match your situation against a version of it they lived through five, ten, twenty years ago. They tell you what worked, what didn't, and what they'd do differently now.
Mentorship is directive. It's not 'here are three questions to consider.' It's 'when I hit that, I did X, and it turned out to be a mistake for these three reasons — here's what I'd do in your shoes.'
Good mentorship saves you the fifteen months it would take to learn the same lesson from the market.
An advisor shapes the structure.
Where a coach works on you and a mentor tells you what to do, an advisor works on the situation. Board dynamics. Deal structure. Governance. The strategy the leadership team is publicly defending but quietly disagreeing with. Advisors sit above the day-to-day. They ask about the shape of the game, not the play.
Good advisors are the reason a board makes a call cleanly instead of drifting for four months.
When you need which
The three roles solve different problems.
You need a coach when the problem is a pattern. You keep making the same kind of mistake. You keep avoiding the same kind of conversation. You keep hiring people you later can't manage. You know something needs to change and you don't know what. This is a coaching problem. Nobody can tell you the answer, because the answer is inside your own operating system and you can't see it. A coach helps you see it.
You need a mentor when the problem is a first. You've never scaled to £10m before. You've never raised institutional capital before. You've never fired a co-founder before. You need someone who has, and who will tell you honestly what they learned. Frameworks don't help here. Experience does.
You need an advisor when the problem is a structure. Board is dysfunctional. Governance is unclear. The M&A conversation is happening and nobody in the room has done one before. You're not looking for personal development — you're looking for someone who can shape the situation before it shapes you.
Most founders and CEOs need all three, at different moments in the same month.
The trap most leaders fall into
They hire one and expect it to be all three.
They hire a coach and are frustrated when the coach won't tell them what to do. (That's the coach doing their job correctly, but it doesn't feel like value in the moment.)
They hire a mentor and are frustrated when the advice, however well-earned, doesn't quite fit their specific situation. (Advice is always general; leaders are always specific.)
They hire an advisor and are frustrated when the advisor doesn't help them with the harder personal question underneath the strategic one. (Advisors solve the game; they don't solve you.)
Each of those frustrations is legitimate. The person hired is not doing the job wrong. They're being asked to do a job they weren't hired for.
The combination that changes everything
Most practitioners can only offer one of the three, because the training paths are different.
- Coaches train through ICF or equivalent programmes — hundreds of hours of supervised practice, a discipline built around asking rather than telling.
- Mentors earn the right through having actually done the thing — usually as founders, operators, or category-shaping executives.
- Advisors develop through board and NED experience, deal work, or specific functional expertise at scale.
Very few people hold all three. Fewer still hold them at the standard required for the leaders we work with.
That's why we've built Jonas Partners around the combination. Warren Jonas is ICF PCC certified — a coach by discipline. A serial founder — a mentor by experience. A board advisor across sectors — an advisor by practice.
The engagement moves between the three modes as the moment requires. Coaching when the answer needs to come from you. Mentorship when direct experience is what's called for. Advisory when the situation itself needs shaping. It runs on our Compass Coaching methodology.
The client doesn't have to work out which they need. That's our job.
The honest question to ask before you hire anyone
If a coach, mentor or advisor is telling you they can do all three, ask them how. What's their coaching training? What have they built? What boards have they served on?
If they can't answer clearly in each of the three areas, they can't do the combination. They can only do one and pretend the others.
That's the market. It's why so many leaders end up hiring the wrong person, being underwhelmed, and concluding that 'coaching doesn't work' or 'mentoring is just war stories.' The problem wasn't the modality. The problem was the fit — and the market's failure to be honest about what each role actually is.
Get the fit right. The work gets easier.
