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. The practice holds three disciplines to a single standard — most practitioners can hold only one: coach by ICF discipline, mentor by real operator experience, advisor by active board practice. Founded by Warren Jonas — ICF PCC certified and Henley-trained, serial founder (Wild & Stone, Robert Lloyd), board advisor across sectors including pharma, mortgages, moving services and consumer products — the Compass Coaching methodology is being extended through associate practitioners trained to the same bar.
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.
Two patterns I see, twenty years in
Pattern one: the founder who hires a coach when they need a mentor.
Frustrating for both. The founder wants an answer — 'just tell me what to do about this hire' — and the coach responds with a question. The founder leaves feeling unsupported. The coach leaves feeling the founder isn't coachable. It's not either of their faults. It's the wrong role for the moment.
The fix isn't a better coach or a more compliant founder. It's naming what you actually need before you hire. If you're facing a decision where the challenge is figuring out what you think, hire a coach. If you're facing a decision where you already know what you think and need someone who's seen this exact shape before, hire a mentor. Different tools for different moments.
Pattern two: the founder who hires an advisor and wants coaching.
Similar mismatch, opposite direction. Founder wants a deep exploration of their own patterns and blind spots. Advisor gives them the industry answer, the framework, the pattern-match from fifty other companies. Founder feels rushed. Advisor feels the founder isn't ready to act on the advice they came for.
Same fix: name what you need first. Advisors compress your learning curve on a category (fundraising, an acquisition, a market entry) by giving you the answer they've already learned. Coaches expand your learning curve on yourself. Both are valuable. Neither substitutes for the other.
The pattern I see most often is founders bouncing between coach and advisor thinking they need a different provider — when they actually need a different role from a different person. The provider isn't broken. The role definition is.
How to know which you need
Three questions to ask yourself before hiring:
1. Do I need someone to ask me questions I haven't thought of, or do I need someone to answer a question I have?
If it's the first, you need a coach. If it's the second, you need a mentor or advisor. Most founders default to 'answer a question I have' because that's what asking for help usually means. But at the founder level, most of the highest-leverage questions are ones you haven't asked yourself yet — which is why the coaching model exists.
2. Am I trying to figure something out, or trying to figure out what to do about something I already understand?
Figuring something out (a values question, a personal drift, a pattern you keep running) is coach territory. Figuring out what to do about something you already understand (a hiring decision, an M&A option, a market pivot) is mentor or advisor territory. Confusing the two is the source of most 'my coach isn't helping' or 'my advisor didn't get it' frustrations.
3. Do I keep bringing the same problem back to my last five leadership meetings?
That's the sign you need a coach + mentor combination. Coaches alone won't move a stuck problem because the founder needs a fresh answer. Mentors alone won't move it because the founder can't hear the answer through their own patterns. The two together — coach making the pattern visible, mentor showing the shape of the fix — is the only combination that reliably unsticks the stuck.
The combination that actually changes things
Almost every founder engagement I've done that shifted the trajectory of a business had the same pattern: coach + mentor combination, held over enough time that both roles could compound.
The coach's job was to make the pattern visible. The mentor's job was to name what shape of fix had worked for other founders at similar scale. Neither alone would have moved it. Coach alone kept surfacing the pattern but couldn't offer a proven fix. Mentor alone kept offering the fix but couldn't get the founder to see the pattern they'd need to fix.
The combination works because the two roles hold different tensions. The coach holds the founder's growth. The mentor holds the founder's competence. Both matter. Both, together, move faster than either alone.
The founders who scale fastest aren't the ones with the best coach or the best mentor. They're the ones who set up the combination early, held it for 12+ months, and let the compounding happen.
Frequently asked questions
What's the difference between a coach, mentor, and advisor?
A coach asks questions to help you find your own answer. They don't tell you what to do. A mentor has been where you're going and offers guidance based on their own experience. An advisor has seen many businesses face the same decision and offers pattern-matched perspective. Coach = your thinking. Mentor = their experience. Advisor = pattern from many experiences. Different roles for different moments.
Can one person be all three?
Rarely, and even when they can, they usually shouldn't try to be all three in the same engagement. The disciplines conflict. A good coach holds space; a good mentor fills it. Switching roles mid-session confuses the founder about which mode they're in. Better: hire different people for different roles, or hire one person who is deliberate about naming which role they're in for each session.
Which one should a founder hire first?
Depends on the moment. If you're stuck on a decision you've been circling for months, you probably need a coach first — the sign of a pattern is that you keep re-visiting the same shape. If you're facing a specific decision you've never made before (first M&A, first fundraise, first market entry), you probably need a mentor or advisor first. If you're not sure, coach first — the coaching conversation will surface whether you actually need mentoring or advice.
When does an advisor become a board member?
When their role shifts from advisory (offering perspective when asked) to governance (accountability for the business's direction). Advisory doesn't require a formal seat. Board membership does. The transition is usually about equity/compensation, formality of meeting cadence, and legal liability. Some advisors resist becoming board members because the governance responsibility changes what they can say. Some founders resist because it changes control dynamics. Both concerns are valid.
How much should each one cost?
Wide range. A coach: £5-15k per year for monthly sessions at the entry level, £30-60k+ for weekly at the senior end. A mentor: often free-to-token in exchange for equity/goodwill at early stage, £10-40k per year for structured programmes. An advisor: £10-50k per year for retained advisory work, higher if formal board seat. Beware: cheapest is rarely best; most expensive isn't always either. The right person at the right price for the right moment is what matters.
Do I need all three at the same time?
Rarely. Most founders benefit from two of the three at any given moment — usually coach + mentor for personal growth + business shape, or advisor + mentor for a specific transition. Having three simultaneously is expensive and can create conflicting signals. Better: one anchor relationship (usually coach) held for years, plus specific mentor or advisor engagements for specific transitions.
Is a mastermind or peer group a coach, mentor, or advisor?
Neither, exactly — it's a fourth thing. Peer groups (like a Business Leader Forum) work by peer pressure and shared vulnerability, not by expert guidance. They complement coach/mentor/advisor engagements but don't replace them. Most founders benefit from BOTH — a peer group for horizontal accountability and a coach for vertical growth.
About this essay
Who wrote it: Warren Jonas — ICF PCC accredited executive coach, Henley Business School trained, serial founder with 20+ years building and exiting businesses across technology, consumer goods, financial services and professional services. Currently Board Advisor across multiple UK and international scaling businesses, and Commercial Director at Temple. Also facilitates two Business Leader Forum groups for CEOs.
How it was written: Drawn from twenty years of playing all three roles — as a founder receiving coaching, mentoring and advising; as a coach and mentor to other founders; as an advisor across multiple boards. Edited and polished with editorial support; core insights are Warren's.
Why it exists: Because most founders waste their outside-help budget by hiring the wrong role rather than the wrong person. Naming the three disciplines clearly — and knowing which one you need for the moment you're in — is the highest-leverage decision most founders make about outside support. If this essay saves ten founders from that specific mistake, it's done its job.
