Build a small, premium boutique practice, without rebuilding the bank.

If you left a bulge-bracket or boutique investment bank after twenty or thirty years, you already know the problem. The calls still come in. Founders want your read before they engage an adviser. Board members want to know whether the process makes sense. Sponsors send you CIMs asking what you think. The judgment is still there. What is gone is the infrastructure that packaged it.

No analyst bullpen. No associate layer. No pitchbook production machine. No buyer database team. No compliance layer. No institutional letterhead. What you had was not a career. It was a platform. And the platform did not retire with you.

The One-Banker Boutique is a Sovereign Executive track from The Leverage Years designed for exactly this situation. It is a ten-module program that helps a retired M&A managing director or capital-markets banker build a lean, risk-controlled, high-fee advisory practice around a small number of founder-led mandates — without recreating a full investment bank.

The mechanism is Claude-anchored infrastructure. Claude is not the product. Your deal judgment is the product. Claude is the support layer that previously required an analyst, an associate, and a VP.

What does that mean in practice?

The course opens with a module on Identity and Market Positioning. The first lesson is called The Institutional Eviction. It asks a direct question: what specifically did the bank provide that you cannot provide alone? The answer is a structured Platform Loss Inventory — an honest accounting of what has disappeared. Brand, buyer databases, process management, pitchbook production, compliance review, CRM, distribution. The module then separates high-value banker judgment from low-value execution work, because the two are not the same thing. Your clients paid for your market judgment, your buyer knowledge, your negotiation instinct, and your capital strategy credibility. They did not pay for EBITDA cleanup in an Excel model. That distinction shapes the entire advisory model.

Module 2 builds the Deal AI Clean Room. Senior bankers do not use AI casually with transaction data. The course introduces a six-tier data classification system and an Anonymization Token System — Company Alpha, Founder One, Buyer Delta, Sponsor Blue — so that sensitive founder, buyer, and transaction information is never entered into any AI tool in identifying form. The architecture is called Anchor-and-Complement: Claude is the primary analytical anchor for synthesis, CIM review, buyer logic, diligence question organization, and client-ready drafting. Complementary tools — Perplexity for real-time research, NotebookLM for bounded document sets, Capital IQ or PitchBook for financial data — are used strictly at the workflow level for bounded tasks. Professional judgment sits above all of it.

Module 3 is the Signature Framework Builder. A retired managing director who offers deal help generically competes on willingness. A retired managing director who offers a Founder Transaction Readiness Review, an Instant CIM Decoder, or a Buyer Universe Engine competes on methodology. The course walks through building each of these frameworks in full, including the nine components every named advisory service requires: buyer definition, transaction problem, inputs, analysis categories, output format, decision value, regulatory boundaries, and exclusions.

What do clients pay for these services?

Module 7 covers AI Premium Pricing, and the answer is: price the transaction decision, not the hours. If Claude compresses first-pass CIM review from forty hours to twenty, that time savings accrues to your margin — not to a lower fee. A Founder Transaction Readiness Review is priced at $15,000 to $35,000 because the value is the decision quality, not the time input. An Instant CIM Decoder runs $10,000 to $25,000. A Buyer Universe Review ranges from $15,000 to $50,000. An ongoing one-banker advisory retainer is priced at $10,000 to $50,000 per month depending on scope and access.

Module 5 introduces the Mandate Intake Protocol — the first client-facing document a new founder receives after signing. It is a polished two-to-three page PDF defining document categories, sanitization standards, secure transmission channels, AI workflow disclosure, and professional boundaries. It signals institutional caliber before a single analysis is delivered.

Module 6 teaches Quiet Authority publishing. The format is called The Banker's Note — short, calm, precise observations from decades of deal experience. Not LinkedIn content. Not thought leadership for its own sake. Signal for a small, high-value audience: founders, board members, family offices, and senior advisors who recognize and trust the analytical frame.

Module 8 addresses the risk layer that every senior banker in this position must confront: the boundary between transaction advisory and regulated services. The Human Approval Matrix defines six approval levels, from internal brainstorming to client-facing deliverable to escalated specialist review. The Regulated-Service Boundary Checklist covers securities advice, broker-dealer activity, placement-agent activity, fairness opinions, valuation opinions, investment advice, and fiduciary exposure. The independent transaction advisor engagement architecture provides the language that separates the advisory role from licensed services in every engagement letter.

The program closes with a 30-Day Implementation Sprint: days one through five on positioning and context, days six through ten on AI infrastructure and risk controls, days eleven through fifteen on signature framework and offer, days sixteen through twenty on authority publishing and rolodex activation, days twenty-one through twenty-five on asset and location leverage, and days twenty-six through thirty on network reactivation and first-client delivery.

Who is this for?

It is for retired bulge-bracket managing directors and former M&A and capital-markets bankers — from Lazard, Evercore, Goldman, Morgan Stanley, JPMorgan, Citi, Bank of America, UBS, and established boutiques — who want to advise on a select number of founder-led transactions without rebuilding a full bank. It is not for people who want to learn AI. It is for people whose deal judgment is still commercially valuable and who need the infrastructure to make it operational at a senior, discreet, risk-controlled scale.

The outcome is a functioning one-banker advisory platform built around thirteen graduate deliverables: the positioning brief, the Deal AI Clean Room, the signature advisory framework, the productized diagnostic services, the AI premium pricing model, the mandate intake protocol, the rolodex activation scripts, and the sales call map.

The program is available at $3,495 self-paced, $8,995 with Advisory Board access, and $25,000 for Private Implementation. Details at theleveragedyears.com/one-banker-boutique.
