Find the Leak · Fix the Weakness · Rebuild the Revenue
Vault Medallion VAULT
Our Mission

Keep more of your best clients.
Earn more from every one.

Four out of five wealthy clients change advisers within two years of an inheritance — and most firms never see the revenue walk out the door. Vault finds exactly where you're losing it — in pricing, retention, and the wrong person in the room — puts a dollar figure on each leak, and rebuilds how you win, keep, and grow the relationships that drive most of your revenue. We bring the revenue you ought to have.

01 · What We Do
Category of one

A consultancy purpose-built for ultra-high-net-worth revenue.

By ultra-high-net-worth we mean individuals with roughly US$30 million or more in investable assets (Knight Frank's threshold). Definitions vary by industry and firm — what matters isn't the label, but that a small number of these clients drive a disproportionate share of your revenue.

Vault works with any firm whose revenue runs through ultra-high-net-worth clients. The category is the buyer profile, not the industry.

Private banks. Family offices. Luxury operators. Premium real estate. High-end advisors. The common thread: a small number of clients who matter disproportionately to the profit and loss — and an operating discipline that has not kept up with the stakes.

Too much revenue is leaking out of firms that depend on the world's wealthiest clients, and almost nobody is built to find it and fix it.

That is the gap Vault was built for. Not training-derived. Deal-derived. Twenty-five years of carrying the pipeline personally, distilled into a methodology that compounds across handlers, across years, across the inheritance moments where most relationships break.

02 · How We Work

Every engagement begins with the Revenue Leak Audit.

The Audit looks at the operation — pricing, positioning, qualification discipline, handler-buyer match, retention cadence, internal selling — and puts a dollar value on each leak found.

Step 01

We Diagnose

The Audit looks at the whole operation and puts a dollar value on each leak found. Pricing. Positioning. Qualification discipline. Handler-buyer match. Retention cadence. Internal selling. Numbered, evidenced, prioritised.

Step 02

We Match the Fix

If the leak is in handler skill, training fires. If it sits deeper — in structure, incentive, leadership — a different engagement does. We deploy what the Audit calls for, not a generic programme.

Step 03

We Compound the Recovery

We rebuild the operating discipline so the revenue keeps compounding — across years, across handlers, across the inheritance moments where most relationships break.

03 · Why Us

Operator-grade methodology. Not theory.

Vault's structural defensibility rests on four visible signals — and two more that compound over time.

Category Creator

No direct competitor in APAC purpose-built to find and fix the revenue leaks of firms whose business runs through ultra-high-net-worth clients. The category exists in the buyer’s mind — the integrated resort, the private bank, the family office all know they have a ultra-high-net-worth operating problem — but the firm purpose-built to fill the category did not exist until Vault.

→ The first move in the category gets the data moat.

05 · Selected Engagements

What recovery looks like.

Anonymized scenarios from twenty-five years on the floor. Every number is real; every name is held in confidence.

If this sounds familiar

It's probably happening to you right now.

Most firms never find out which of these is costing them — or what it's worth. The Revenue Leak Audit does, to the dollar.

01

The inheritance you didn't see coming

Fifteen years with a family; the patriarch passes, the children move the account within a year, and no one warned you.

02

The discount you can't see

You quietly shave the fee on every renewal "to be safe." Across the book, it's a six-figure habit hiding in plain sight.

03

The wrong person in the room

Your best closer keeps losing your most important prospect — the wrong personality for that buyer, never matched on purpose.

04

The book that lives in your head

If you left tomorrow, a large share of the firm's revenue would walk out with you.

05

The calls you only make when you want something

Your competitor calls your top clients when they don't. Guess who gets the next deal.

06

The quiet families you're losing

The three relationships that carry your profit feel taken for granted — and have started taking meetings elsewhere.

07

The record sale you never followed

You closed a career-best deal last year. They've bought twice more since — from someone else.

08

The referrals you never ask for

Every top client knows five people just like themselves. Your most profitable growth channel sits idle.

09

The stakeholder you never met

A deal you were sure of died at the final meeting — because you never met the spouse, the lawyer, or the mother who decides.

10

The price you gave away

You dropped the price to win, and never found out they'd have paid full freight if you'd held your position.

Who we serve

Built for whoever carries the wealthiest relationships.

If your revenue runs through a small number of very wealthy clients, Vault is built for you — whatever the industry on your business card.

Private bankers

Grow the book, don't leak it

The children inherit and move the money, you discount the relationships you value most, and the book lives in your head. We rebuild pricing and hand-offs so it grows.

Family-office advisers

Keep the mandates that matter

Families drift at succession and fees keep shrinking. We re-sort the book by who truly matters and build the rhythm that keeps them.

Luxury property brokers

One sale into a lifetime

Repeat ultra-wealthy buyers treated as one-off deals, discounted to close. We turn one sale into a stream of referrals — and teach you to hold price.

Casino & resort hosts

Right host, right whale

The wrong host on the wrong guest, and no plan to win them back. We match host to guest and rebuild reactivation around real worth.

Art & collectibles advisers

Past the single sale

The relationship ends when the deal closes. We build the long game that turns one acquisition into many.

Yacht & jet brokers

Stay in front, hold margin

Long silences between purchases, always chasing new names. We keep you present with proven buyers and protect your margin.

Private-client lawyers

Trust into expansion

Deep trust you never extend to the family's other needs. We turn that trust into more work and a steady flow of referrals.

Wealth managers

Protect a concentrated book

A book riding on a few clients, renewals assumed. We fix the adviser-client fit, earn the renewals, and protect the book.

Representative outcomes (illustrative — real engagements are confidential under NDA): a private bank where the Audit traced about S$8 million a year leaking through discounted renewals and two mismatched bankers; a family office spending a third of its effort on clients who didn't need it while three top families drifted; a luxury developer sitting on tens of millions in unclaimed repeat-and-referral revenue.

Our Commitment

We don't refund. We work harder.

If the results we agreed aren't there, we keep working with you — at no further fee — until the engagement has earned you back at least twice what you paid Vault, in revenue or commissions directly attributable to the work.

Applies to the Accelerator and above, and forms part of your engagement agreement — against outcomes agreed in writing before work begins, and conditional on you implementing the agreed moves. Full terms govern.

10 · The Honest Answers

The questions that actually decide it.

Twelve questions Vault is asked most often by buyers considering a $39,997 Mastery or a $1M Embedded Engagement. The answers below are the ones Marcus gives in the room. No corporate hedging.

How long does a typical Vault engagement take?

The Snapshot is three days. The Standard Audit runs 2–4 weeks. The Forensic Audit runs 4–6 weeks. The Core Programme runs 3–6 months. The Embedded Engagement is multi-quarter. Individual programmes range from a single 60-minute debrief to the Sanctum's 5-day immersion plus 3-month council container. Every engagement begins with an Audit, and the Audit determines what fires next. The pace is set by what the Audit finds, not by a sales calendar.

What time commitment does the engagement require from my team?

An audit typically requires three to five hours from key stakeholders over the engagement window — one 90-minute interview each from the commercial leader, the COO, the head of CRM, plus a kickoff and a debrief. Vault does its own data work. We pull what we need from CRM exports and prior board materials rather than asking your team to compile briefs for us. The time-from-your-team economics of a Vault audit are favourable compared to the major strategy firms by design.

What confidentiality protections are in place?

ultra-high-net-worth client confidentiality is treated as a foundational duty. Every engagement operates under signed NDAs with mutual obligations. Internal Vault delivery is single-team and need-to-know. Case material is anonymised by default and never published without explicit, documented permission. Client identities are not disclosed in proposals or pitches to other prospects, full stop. Discretion is part of the brand register, not a contractual line item.

How is success measured?

For an Audit: a calibrated revenue-leakage range, prioritised remediation list, and a recommended Vault programme matched to the findings. For a Programme: success criteria are defined and agreed in the engagement letter before kickoff, calibrated to the buyer’s specific situation. For Corporate engagements: the 60% re-audit clause — at the 12-month mark Vault returns and re-runs the diagnostic; if the headline leak has not measurably narrowed, sixty percent of the original audit fee is credited back, payment 50/50. We hold the price even if it costs the deal.

What if we already have a sales training partner in place?

Vault is not a sales-training vendor. Vault is an audit-led revenue-recovery consultancy that sometimes deploys training as the remediation when training is what the Audit calls for — and just as often deploys structural, operational, or cultural interventions instead. Most sales-training spend produces 90 days of improvement followed by full reversion because it was applied to a problem training cannot fix. The Audit’s job is to name the true category before any remediation is sold.

What makes Vault different from McKinsey, BCG, or Bain?

The major strategy firms staff partners who advise on commercial strategy from a research and analytics perspective. Vault is led by a principal who personally carried AUD 45B in turnover (~AUD 605M revenue) across Las Vegas Sands, Crown Resorts, and The Star Entertainment Group. The methodology is not derived from training a methodology, then applying it. It is derived from running a AUD 45B turnover book (~AUD 605M revenue) for four years and then codifying what made it work. Where the major firms are broader and more institutionally resourced, Vault is deeper, more operator-grade, and category-specific to ultra-high-net-worth revenue recovery.

Why is the pricing fixed? Do you offer discounts?

The pricing ladder is engineered to protect perceived value across the entire suite. Discounting at any tier dilutes the premium positioning of every product on the ladder permanently. The price is held even if it costs the deal. What is negotiable is scope and sequence — we will engineer a smaller engagement to fit a tighter budget. What is not negotiable is the price of the engagement as scoped. Operator-grade firms hold their pricing. So does Vault.

What does the 60% re-audit clause actually mean?

For every corporate engagement built on a Vault audit, twelve months after delivery, Vault returns and re-runs the same diagnostic against the same baseline. If the headline revenue leak has not measurably narrowed, sixty percent of the original audit fee is credited back. Payment terms: 50% on engagement signature, 50% on the 12-month re-audit (with re-audit fee credited or refunded if the headline leak persists). The clause keeps Vault accountable to the standard Vault sells. Most consultancies will not write this clause. We do.

Can an engagement be paused mid-stream?

Yes, with notice. Engagements can be paused if a buyer’s operating environment changes materially — M&A activity, leadership transition, regulatory event — provided the pause is documented and a restart timeline is agreed. Engagements that are paused for more than 90 days require a rescoping conversation rather than a simple restart, because the operating context will have moved.

What if Marcus is unavailable during the engagement window?

The “Marcus-permanent” rule applies to Forensic Audits, the Core Programme, Embedded Engagements, the Partnership, the Patron, the Mastery, and the Sanctum tiers. These are non-transferable — Marcus delivers personally. If Marcus is genuinely unavailable for a critical milestone, Vault will reschedule rather than substitute. For Snapshot, Standard Audit, Self-Audit, Foundation, Assisted Audit, Accelerator, and Team Pilot tiers, Senior Vault Practitioners (and from Q3 2026 onward, certified Whale Wrangler Trainers) carry delivery alongside Marcus.

Do you work with smaller firms or earlier-stage operators?

The Individual Pathway is built for operators carrying their own ultra-high-net-worth relationships: private bankers, family-office leads, premium real estate brokers, hospitality directors, advisors. The Self-Audit at $497 is the entry point. The Foundation at $1,997 is self-paced. Smaller firms enter through the individual ladder rather than the corporate ladder. If a firm has fewer than 30 commercial staff but a defensible ultra-high-net-worth book, Snapshot ($15K) is generally the appropriate first engagement.

What is the next move? How do we actually start?

Two paths in. Path one: take the free WHALE Code™ Handler Read — 60 questions, ~12 minutes — for your initial WHALE Code animal profile and a preliminary read of your operation. Path two: book a thirty-minute Revenue Leak Diagnostic call with Marcus. No commercial pressure. Marcus reads the operation as you describe it and tells you whether a paid Audit is appropriate. The honest first move.
