Advisory

A private world, entered by recognition rather than application.

Boris keeps close counsel with a small number of principals. There is nothing to buy on this page. Request the letter, or write to him directly — every note is read by Boris himself.

By invitation · By recognition
What this is

A consigliere is not a coach, a vendor, or a board seat. It is one trusted mind in your corner — private, candid, and entirely without an agenda of its own.

By the time most people find their way to this page, they already know who Boris is. The question is no longer whether the counsel is good. It is whether this kind of relationship — quiet, unhurried, accountable to no one but you — is the one they’ve been missing.

It is, by design, not for everyone. There is no program to enroll in, no tier to climb, no list to join. Only the quiet value of the right counsel at the right moment, given in confidence — a relationship, not a transaction.

What it runs on

Three things the accomplished rarely find elsewhere.

01

Candor, with care.

The truth no one else in the room will say — delivered plainly, and on your side. Not to wound, but because you can’t steer by flattery.

02

Confidentiality, sealed.

A space for the decisions and doubts that can’t be spoken to family, partners, or the team. What is said here stays here.

03

No agenda but yours.

The rare relief of counsel from someone who wants nothing from you in return. No upsell, no product behind the advice.

Who this is for

You will know if it’s you.

Entry here is by recognition, not application — so the right person sees themselves at once, and the wrong fit can pass without friction.

This resonates if
You’ve built something real — a mature company, and a name that carries weight.
You carry decisions you can’t fully share with family, partners, or your team.
You’d rather hear the unvarnished truth than be reassured.
You want one unbiased mind to think alongside — not another service.
This isn’t for you if
You’re looking for a cheerleader, or a quick tactical fix.
You’re early-stage and need hands-on operational help.
You want a guru, a methodology, or an off-the-shelf program.
You’re not yet ready to hear — or act on — an honest outside view.

If you saw yourself on the left, that recognition is the whole of it. Nothing more is asked.

The letter

The Chasm and the Castle.

It’s the long-form piece of writing where Boris lays out, plainly, how he sees the world a successful founder actually lives in — the chasm most never name, and the castle few learn to hold.

He’s happy to send it to you personally. Not a download in exchange for your details, and not the opening of a sequence — simply a way to get to know how he thinks before any conversation begins.

From the letter
“The hardest discipline in the age of AI is not learning AI. It is refusing the Rabbit.”
— Boris Blum, The Chasm and the Castle
A private note

A way to get to know him.

Not an application to be approved on paper — just an introduction. Tell him a little about who you are and what brings you here. If there’s a fit, you’ll hear from him directly. You’re welcome to ask for the letter while you’re here.

Held in strict confidence. Read by Boris, and no one else.


The right people tend to recognize themselves in all of this. If that’s you, he’d be glad to hear from you.
