What A Mentor Should Give You, And What They Can't
Starting this April, I’ve taken on the role of Accompany Runner (AR) at NEDO’s NEP (NEDO Entrepreneurs Program).
This position provides hands-on support for building business models, aimed at individuals and teams pursuing startups in deep tech fields.
For details, see the NEP special site, but roughly speaking, it’s positioned as an “experienced accompany runner.”
After receiving this offer, I found myself thinking through, once again, what I should provide as an accompany runner, and what I can’t provide.
I’ve felt something similar through my work as an advisor or consultant at individual companies up to now.
This time, though, I’ll be responsible for people selected through an open call, so unless I properly design expectations in my own mind, the arrangement won’t be fair to either side.
Rarely does anyone ask me point-blank, “What does a mentor actually do for you, in the end?”
Few people ask that directly to someone’s face; most just feel a gap between expectation and reality, sense the mood getting worse somehow, and drift away.
That’s exactly why the mentor side needs to sort this out for themselves.
I myself have served in a mentor-like capacity at several companies, and conversely, there are a few people I would call mentors to me.
So I should be able to speak about “what a mentor is” with some real feeling for it, but every definition I try ends up sounding somewhat hollow.
“An experienced advisor” is too tidy a phrase.
“Someone who tells you the right answer” is clearly wrong.
“Someone who connects you with industry contacts” — that’s part of it, but not the essence.
This NEP assignment gave me the occasion to sit down and sort this out properly, and I arrived at an answer that’s consistent for me.
I want to write that down here.
What you shouldn’t expect from a mentor
First, it’s easier to start by sorting out what you shouldn’t expect.
Get this wrong, and the relationship distorts for both mentor and mentee.
① They are not someone who gives you the right answer
The general premise is that a mentor is involved as someone with more experience than the mentee.
But having more experience doesn’t mean they’ve experienced everything the mentee is currently facing.
Circumstances differ from person to person, and the times are different too.
So if you frame a mentor as “someone who has the right answer,” the relationship will inevitably drift out of alignment somewhere.
This breaks down even more seriously if the mentor themselves starts acting like “someone who gives the right answer.”
② Introducing contacts doesn’t necessarily lead to a solution either
Once a mentor has accumulated a certain amount of experience, there are situations where they can help the mentee through their network of contacts.
But the person they’re introduced to won’t necessarily solve the mentee’s problem.
In the end, only the mentee can solve the mentee’s problem.
An introduction only creates a point of contact; it doesn’t create the answer.
③ Personal anecdotes aren’t necessarily useful as they are, either
Stories like “back when I was young, this is how it was” are ones a mentor can tell with real pleasure.
But an anecdote only works for problems with the same structure — it doesn’t work for a different structure.
In fact, applying an anecdote to a situation that looks similar but is actually different will push the mentee in the wrong direction.
An anecdote should be offered as one reference point among others, not as a prescription.
Lined up this way, what a mentor has to offer looks fairly unreliable.
If “the right answer, contacts, and anecdotes” are all not necessarily useful, the question becomes: what is this role even for?
That’s precisely why I think lowering expectations once is the right move.
Rather than being trusted excessively, making it clear from the start that “in this sense, I won’t be useful” produces, in the end, a relationship that functions over the long term.
What a mentor “can definitely provide”
So, having lowered expectations, what can be guaranteed?
- Listening closely and staying by the mentee’s side
- Always being on the mentee’s side
- Not abandoning them
- Having little direct stake in the outcome
This isn’t governed by the amount of experience or knowledge one has.
Intention alone can guarantee it.
And for the mentee, there actually aren’t many other people who offer this combination.
A boss is an evaluator, so it’s hard to speak honestly to them.
A colleague is also a rival.
An investor has a stake as a financial backer.
Family and friends are on your side, but the dimension of the worries often doesn’t match up.
In other words, a person who satisfies all three conditions — “being on your side,” “being able to talk it through,” and “having little stake in the outcome” — is surprisingly rare in everyday life.
A mentor is in a position to deliberately satisfy these three conditions.
I think this is the core value.
If I had to sum it up in one line, the phrase that fits best is something like “an experienced older brother figure who always listens as your ally.”
Not excessive, and not insufficient either.
Why this is urgently needed — the reality of a leader’s isolation
From here, this is especially about business owners and executives, but the higher up the position, the fewer people there are left to talk to.
You can’t show weakness to your employees.
Even more so, there’s no way you can voice internal complaints to shareholders or stakeholders.
Family and friends are always on your side, but the granularity of the worries is simply different.
Bank negotiations, capital policy, staff reductions, negotiating with investors, resignation talks — dealing seriously with this kind of thing in an ordinary conversation with family is structurally impossible.
As a result, there’s no one to talk to.
The quality of decision-making drops, and it wears on you mentally too.
This isn’t unique to business owners; I think it’s a structure common to anyone in a position carrying a certain level of responsibility.
This is exactly where a mentor delivers value.
Because they’ve experienced situations that are just as difficult, or worse, the context comes through.
Because they also know people with a variety of backgrounds, they can respond either with “I understand” or “I know someone who would understand.”
And because their stake in the outcome is low, they can be candid.
Once you understand this structural inevitability, you can see that the question “what should you expect from a mentor” is part of the larger question of “how do you design for the isolation of business owners and leaders.”
The hidden benefit of listening
I want to add just one more point.
A mentor’s act of “listening” carries a benefit that goes beyond a merely passive role.
By putting into words what they couldn’t tell anyone else, the mentee organizes their own thinking.
In other words, even without the mentor supplying the right answer, they support the process by which the mentee themselves gets closer to it.
Anyone who has run hiring interviews or coaching sessions knows this: people often only realize what they actually think once they start speaking to someone they trust.
A mentor provides exactly that opportunity to speak.
In this sense, “listening” is not a passive act.
It might, in fact, be the point in a mentor’s work where they deliver the most solid value.
Summary — mentorship as expectation design
To sum up:
- Areas where you should lower expectations — the right answer, contacts, and anecdotes are all uncertain; don’t see a mentor as “someone who gives you the answer”
- Value that can be guaranteed — being on your side, listening, not abandoning you, having little stake in the outcome
- Structural inevitability — business owners and leaders are structurally prone to isolation, and a mentor is positioned to receive that isolation
- In one line — an experienced older brother figure who always listens as your ally
Whether I’m the one requesting a mentor or the one acting as one, this is the framing that has clicked into place for me.
Being expected of too much is uncomfortable, and being underestimated doesn’t sustain the relationship either.
Making clear up front what you “can’t do,” and then reliably providing what you “can do” — this, I think, is the key to a mentor relationship that functions over the long term.
And this is, in fact, a design principle for trust relationships in general, not just for mentorship.
As an AR for NEP, I want to approach the entrepreneur candidates I’ll be working with in this spirit.
The right answer is something to search for together, not something I already hold.
But what I can provide, I will provide steadily and reliably.
That’s all there is to it.
