I've run MentorCruise since 2018 and went full time on it in 2020, in the middle of a pandemic. It's profitable, it has a team of five, and there are 6,700+ mentors on the platform. I've spent years on operating problems, and years on the question of whether the thing I was operating was the right thing. Those felt nothing alike from the inside. They look identical from the outside, which is exactly why people buy the wrong one.
The market doesn't help. "Business coach" is a title anyone can adopt tomorrow, and startup advice attracts people whose whole qualification is having watched startups from nearby. Nobody accredits either role. There are coaching credentials you can go and earn, and not one of the bodies issuing them can stop a person practicing without one. So the entire weight of the judgment lands on what the person has actually done. That's a harder check than reading a credential off a profile, and a better one, and most of it can be run before you pay anybody.
The short version
- If your main uncertainty is whether the business should exist, you want a startup mentor. If it's how well you're running a business that already works, you want a business coach. That's the whole call.
- Run it as a one sentence test: write down the question you'd most want answered in the first hour, then ask whether a good answer changes what you're building and who for, or how you run what you've got. First one is an existence question, second is an operating question.
- If you write two sentences instead of one, you're in the middle case: revenue coming in and still not sure the business is right. There's a separate three check test for that below, and its default is the mentor.
- Both roles are unaccredited, so verify the same way in both: what they've actually operated or built, how recently, and what they'll show you before you pay.
- A person worth hiring can tell you who they're wrong for. If nobody is ever the wrong client, you're reading marketing.
Two problems that look the same from outside
How do you tell a business coaching problem from a startup problem? Ask what a good answer would change. If it changes what you're building or who you sell it to, the thing itself is in question and you need pattern matching against many attempts. If it changes how you run what already exists, the thing is fine and the execution isn't, and you need operating discipline. Same founder, same bad week, two different hires.
Here's the test in full. It takes about a minute. Write down, in one sentence, the question you'd most want answered in the first hour with this person, then ask what a good answer to it would change.
Existence questions. "Should I keep going with this?" "Are we going after the wrong market?" "Is now the time to raise, or is now the time to stop?" A good answer changes the shape of the company, and what you need is someone who has watched a lot of companies arrive at that fork and can describe what the ones who chose each way looked like at the time. That's a startup mentor.
Operating questions. "Why does everyone I hire leave inside a year?" "How do I get out of every sales call?" "We're busy and the margin is falling, where's it going?" A good answer changes how the week runs, and what you need is somebody who will hold a process on you and measure whether it moved. That's a business coach.
The test works because it classifies your own sentence instead of weighing up factors. You don't have to be right about your business. You only have to be honest about which question you're carrying around.
If you genuinely have one of each, sequence them rather than blending them. The existence question goes first, always, because operating improvements to a business that shouldn't exist compound in the wrong direction. Getting better at running the wrong thing is the most expensive way I know to spend a year.
We run separate pages for business coaches and business mentors, and people ask me why we don't merge them. This is why. On the coaching page you're shopping for someone to run a process on your operating problems. On the mentor page you're shopping for someone who has been where you are and will tell you what they saw. The startup coaching page is the sharper end of the second one, where the questions are about formation rather than operation.
None of this is the general coach versus mentor distinction, which is a different axis and already answered in full over on coaching vs. mentoring.
The middle case: revenue coming in, business possibly still wrong
What if you have customers and you're still not sure the business works? Revenue doesn't settle the existence question, it just makes it more expensive to ask. Three checks separate the two: whether the problem regenerates after you fix it, whether your revenue is a market or a set of relationships, and whether your plan needs the market's permission. Two out of three points at a startup mentor, and you should go there first.
This is where the tidy answer breaks. Plenty of businesses have real customers, real invoices and a real payroll, and are still the wrong business.
Check one: does it come back? Have you fixed this exact problem before and watched it return within two or three quarters? A correct fix that doesn't hold isn't an operating failure. Something about the shape of the business keeps regenerating the problem, and you'll fix it again next year. That's structural, and structural is mentor territory.
Check two: is that revenue a market or a network? If most of your income comes from a handful of customers who found you through people you already knew, you have a set of relationships. Relationships are worth a lot and they aren't evidence that a market exists. Plenty of founders spend two years improving delivery for a handful of clients who all met them at the same conference.
Check three: does the plan need permission? Hiring, delegation, a weekly operating rhythm: those are inside your control. Whether anyone will pay more, or switch from what they use now, is not. If every version of your fix routes through convincing the market to want something it currently doesn't, you're making a bet about the thing and calling it execution.
I got this wrong in my own company. I launched MentorCruise with hourly pricing, and within three months I realized the model was broken: mentors optimized for billable hours instead of outcomes. That looks like an operating problem right up until you notice the pricing model is producing the behavior. You can run a broken model better. It stays broken.
What they've actually done, and how recently
How recent does the experience need to be? Less recent for a coach than for a startup mentor, and this asymmetry is the thing most people miss. Operating skill ages slowly. Delegation, hiring, cash discipline and getting out of your own way work roughly the way they did ten years ago. Startup formation ages fast. How you raise, where distribution comes from and what a market will pay all move inside a couple of years.
So the question is the same for both and the bar is different.
For a business coach, ask what they've operated. Not how long they've been coaching, and not the size of the largest company on their client list. Have they carried a P\&L. Have they hired someone, then let someone go, then had to tell the team. Have they set a price and lived with what it did to demand. Honest concession: a coach doesn't have to have run your business, and plenty of good ones haven't run any. If that's the case, the substitute isn't a methodology name. It's the specific operating problem they've coached repeatedly, told back to you with what changed. "I've worked with a lot of founders on delegation" is a category. "Here's what founders do in month one when they stop taking the calls, and here's the part that goes wrong" is experience.
For a startup mentor, ask how many attempts they've seen and how many they owned. Both are real datasets and they aren't the same one. Someone who has sat on a lot of boards has seen a lot of companies from a seat that is useful and isn't the founder's. Someone who took their own company to a decision point knows what the call feels like with your own money and your own people, and has a very small sample. Ask which you're buying, and ask what stage: pre revenue and post Series A advice are different jobs with different failure modes.
Then apply the recency bar where it bites. Fundraising advice from someone whose last live raise was in a different market is a historical account. It might be a very good one. It isn't a current map.
I've built thirteen side projects over six years, and MentorCruise was the third. The useful part isn't the one that turned into a company, it's having thirteen early stage data points instead of one, because pattern matching needs a pattern. That's the actual asset a startup mentor is selling, and it's fair to ask them to size it.
The general version of these questions, for choosing any mentor rather than a business one, is in the companion piece on what a career mentor actually does.
What you can see before you pay
What can you actually check on a business coach or startup mentor before money changes hands? Three artifacts, and none of them is a bio. A profile that gives you the object of the verb rather than just the verb. Reviews written by someone whose problem resembles yours. And a free intro call where you bring one real decision and watch what they do with it. All three are available before you commit to anything.
The noun test on the profile. "Scaled teams" is a verb missing its object. Scaled which team, from what to what, doing what work? You're not demanding a metric, you're asking for a noun. Whether the profile supplies one without being asked is itself the signal, because people who have done specific things tend to name them.
Read the reviews sideways. We have a 4.9 out of 5 average across 20,000+ reviews and that number is close to useless to you as an individual buyer. What's useful is whether any reviewer had your problem. Five stars from a founder who was raising a seed round tells you nothing about whether this person can fix your hiring funnel. Search the reviews for your situation, not for the score.
The intro call, coach version. Ask what the first four sessions look like, and ask what would count as it not working. The second question is the one that matters. If there's no answer to it, there's nothing to hold them to and you've bought conversation. A coach who names the measure up front has handed you the thing you'd fire them with.
The intro call, mentor version. Ask about a company they advised that didn't make it, and what they now think they missed. Real datasets have losses in them. A track record that is all wins is either very short or it's a marketing page, and the answer tells you which inside ninety seconds.
One extra for startup people: the public prior. Is there anything they wrote or said before the outcome was known? A post, a talk, a newsletter from four years ago that made a call. Anyone can explain why a company won after it won. Very few have a public record of what they thought while it was still uncertain, and that record is the best evidence going that the pattern matching is real.
The tells that should stop you
What are the warning signs specific to this market? Six, and they're all versions of the same thing: a claim you can't check, dressed as a claim you can. Unbounded practice areas, observer experience sold as operator experience, diagnosis arriving before questions, proximity presented as a track record, stale fundraising credentials, and a person who can't name anyone they're wrong for.
-
The unbounded practice. Someone who coaches business, mindset, leadership, relationships and money. Breadth is the tell, because operating knowledge is specific and hard won. A person who can help with all of it has usually built a method that's about you rather than about the business, which is a legitimate product and not the one you came for.
-
Observer experience sold as operator experience. "I've worked with over 200 startups" is a real qualification for a specific job. It isn't the same as having run one. The tell isn't the claim, it's the blur, and one question clears it: which of those did you make decisions in?
-
Diagnosis before questions. If someone reaches a firm opinion about your market in the first ten minutes, they've matched you to a template. Speed of diagnosis is an inverse signal in both roles. What you want in a first call is someone asking things you have to go and look up.
-
Proximity as track record. Being at a company while it worked isn't the same as having made the calls that made it work. Ask what they personally decided and what they'd decide differently now. Good people answer this happily.
-
The stale raise. For anyone selling fundraising help: when did you last do this, and with whom. Terms and investor expectations move fast enough that a raise from a very different market is a story rather than a map.
-
Nobody they're wrong for. Covered next, because it's the whole ballgame.
What each one is wrong for
When should you not hire either? A business coach is wrong for you if the honest answer is that the business doesn't work, because coaching will make you better at running it. A startup mentor is wrong for you if you already know it works and the real problem is that you personally won't delegate. And both are wrong when what you're carrying is a capital problem, a co-founder problem, or burnout.
A business coach is the wrong hire when the thing is broken. A good coach will build the operating rhythm, get the hiring loop working and get you out of the middle of everything. If the business shouldn't exist, all of that is real improvement pointed in a direction that doesn't pay. Coaching is an amplifier and it doesn't check the sign.
A startup mentor is the wrong hire in two situations. The first is when you already know the model works and the constraint is you: you won't hand over the sales calls, you won't let anyone else own the roadmap, you keep rewriting other people's work. No amount of market pattern matching fixes that. It's a behavior problem and it responds to structure and accountability, which is what coaching is for. The second is when you've already decided and want the decision confirmed. A mentor's value is disagreement, and if you're not going to change your mind, you're buying an expensive nod.
Neither is the answer when the problem isn't advice. Some of what founders bring to a first call is a funding gap that needs a bank or an investor, a co-founder dispute that needs a lawyer and a signed document, or exhaustion that needs a doctor. I'd rather say that plainly than let someone spend three months of sessions on it. Mentorship compresses time on problems where knowing what to do is the bottleneck. It does very little where knowing isn't.
A marketplace is wrong for some of this too. If what you need is someone in the room three days a week, holding a stake and carrying real responsibility for outcomes, that's an advisor or an operating partner, and it's a different transaction with equity in it. What we're good at is the recurring hour with someone who has done the specific thing. If you need the other one, go and get the other one.
So: take the sentence you wrote earlier and go to the page that matches it. Operating question, business coaches. Existence question, startup coaches, or business mentors if your problem is broader than the startup framing. Run the profile checks on three people before you talk to anyone, then spend the free intro call on the two questions above. If the answers don't come back clean, that's the system working. Not booking anyone is a legitimate outcome, and a much cheaper one than three months of the wrong help.
Frequently asked questions
What's the difference between a startup mentor and a startup advisor?
Mostly the contract and the stake. An advisor usually has a formal relationship with the company, often equity on a vesting schedule, and is expected to be reachable and sometimes to open doors. A startup mentor is a recurring paid relationship with you rather than with the company, with no ownership and no obligation to the cap table. Want someone whose incentive is tied to the outcome? Advisor. Want frequent unfiltered input without giving away ownership? Mentor.
Do I need a business coach if I'm a solo founder with no team?
Check whether your problem survives the absence of other people. Delegation, hiring and management problems need a team to exist. Pricing, sales process, focus and the pull toward the interesting task instead of the important one do not, and those are all coachable solo. If your list is mostly the second kind, a coach works. If it's mostly the first, you're describing a problem you don't have yet.
Should I get a startup mentor before I have a product?
Yes, and that's arguably the highest value point. Before there's a product, almost everything you're doing is an existence question: who this is for, what they do instead today, whether the wedge is the right one. Those are exactly what pattern matching helps with, and they get expensive to revisit once you've built. What to bring isn't a pitch. It's the two or three decisions you're stuck between.
How do I check a business coach's credentials?
You mostly can't, and that's the point. There's no license to practice and no regulator to complain to, so a certificate tells you someone completed a program rather than that anyone stands behind them. Replace the credential check with the evidence check: what have they operated, which specific problem have they coached repeatedly, what changed, and what will they show you before you pay.
Can a business coach help me decide whether to shut the business down?
That's a startup mentor question. A coach's job is to help you run the thing better, which quietly assumes the thing should keep running. Someone who has watched companies wind down, and has seen the difference between founders who stopped in time and founders who didn't, is who you want in that conversation. Ask them directly whether they've been through a shutdown, on either side of it.
