Selling a business is one of the most financially complex events of your life. In the weeks and months that follow, you will face an enormous volume of decisions — tax elections, entity restructuring, estate plan updates, investment allocation, insurance analysis, real estate, and more — all while managing the emotional weight of a major transition. The quality of the advisor you choose at this moment will shape outcomes you will live with for decades.
Most founders approach this decision the wrong way. They interview a few wealth managers, review pitch decks, and make a selection based on AUM, brand name, or a warm referral. That process is almost guaranteed to miss the questions that actually matter.
What follows is a framework for evaluating a wealth manager when a significant liquidity event is on the horizon or has just occurred. It is blunt by design — because the stakes are too high for anything less.
1. How Are You Being Compensated During the Pre-Sale Phase?
If you are still working toward a sale — negotiating with investment bankers, restructuring ownership, updating estate documents, evaluating offers — you likely do not have sufficient liquid assets to make an AUM-based fee make economic sense for either party.
An AUM fee on $1,000,000 generates $10,000 per year at a 1% rate. The work required to properly support a founder approaching a $20M+ liquidity event — tax planning, entity structuring, estate coordination, offer evaluation, earnout negotiation — can easily represent 200 to 400 hours of high-skill advisory work. There is no universe in which $10,000 supports that work at the level it deserves.
If an advisor is willing to serve you on an AUM basis during the pre-sale phase without flagging this mismatch, one of two things is happening: they are planning to underdeliver, or they are absorbing the pre-sale work as a loss leader and recouping it on the back end. Neither outcome serves you.
The right structure for the pre-sale phase is a consultative fixed-fee arrangement — scoped, priced in advance, and decoupled from portfolio size. Most founders have ample income to support this model. Ask every prospective advisor directly: “If I'm not yet liquid, how do you structure the engagement, and what does it cost?” Their answer will tell you more than anything in their pitch deck.
2. Can I See an Anonymized List of Every Household You Personally Advise?
This is the question most advisors are not expecting — and the one that most directly separates those who are genuinely equipped to manage post-exit wealth from those who are not.
After your liquidity event, your household AUM increases significantly. The question you need answered is whether your prospective advisor has substantive, ongoing experience managing wealth at your new scale, or whether you are about to become their largest client. Both situations exist in the market. Only one is acceptable.
Standard verbal reassurances — “we work with ultra-high-net-worth clients” or “our average account size is $X million” — are inadequate. Averages are easily distorted by a few large outliers and reveal nothing about whether this specific advisor, sitting across from you, personally serves clients at your level.
What to ask instead: request an anonymized list of all households managed by the advisor or the team that would specifically serve you. The list should include each household's approximate AUM and how long they have been a client. When you review it, look for:
- The full range of AUM sizes across the book
- The median household AUM — not the average
- How many households have assets equal to or greater than what you will bring post-liquidity
- How long the advisor has held their largest relationships
If the advisor cannot or will not produce this — citing “privacy,” which anonymization fully addresses — that is a meaningful signal. An advisor who is confident in their practice will share it.
3. Name the Professionals You Refer Most Often, and Tell Me About Those Relationships
The complexity of post-exit wealth does not stay inside a brokerage account. It extends into estate law, tax law, insurance, M&A advisory, real estate, and sometimes aviation, philanthropy, and divorce law. An advisor who cannot coordinate across those disciplines is not a wealth manager — they are a portfolio manager with a large title.
Before entering any relationship, ask your prospective advisor to name the professionals they work with most frequently in each of these categories: estate and tax attorneys, CPAs, insurance specialists, M&A advisors, and real estate professionals. Then ask:
- How long have you worked with each?
- How many shared clients do you have?
- What does coordination actually look like in practice — when a client has a complex need, what happens?
If they cannot answer those questions in specific, concrete terms — names, years, and real numbers — that is a red flag. A deep professional network takes years to build and is the result of delivering results for shared clients repeatedly over time. It cannot be manufactured for a pitch meeting.
Consider taking it one step further: contact those professionals directly. Ask the estate attorney or CPA whether they actively refer to this advisor, how long they have known them, and what working together is actually like. Professionals who have genuine collaborative relationships will speak warmly and specifically. Those with a looser connection will tell you a different story.
4. Will My Assets Be Held at a Single Custodian?
If a wealth manager proposes holding all of your assets at a single custodian — whether that is Schwab, Fidelity, Merrill Lynch, or anyone else — understand what that arrangement costs you before you agree to it.
Multi-custodian architecture is not a preference for complexity. It is a financial decision with measurable consequences.
Cash and lending rates
Different custodians offer meaningfully different rates on cash balances and margin lending. On $15M in liquid assets, a 50-basis-point difference in cash rates is $75,000 per year. That is not a rounding error.
Derivatives and structured products
If you have a concentrated stock position or need to hedge an equity exposure, dealer spread on options and structured products varies by custodian — and by how much leverage your relationship gives you. A client captive to a single custodian has no leverage. A client with assets distributed across relationships can credibly direct flow, and custodians price accordingly.
Trading costs
For families doing meaningful equity trading or rebalancing, bid-ask spreads and transaction costs differ across platforms. In aggregate, those differences compound.
Proprietary product conflict
A custodian that is also a product manufacturer has a structural incentive to place your assets in their products. That incentive does not disappear because your advisor holds a “fiduciary” title.
The right question to ask is direct: “What is your philosophy on custodian selection, and do you work across multiple custodians?” An advisor who works only within a single custodial relationship — by choice or by contractual constraint — cannot fully optimize your outcomes. Ask why.
5. Can You Advise Me on Everything — Not Just My Portfolio?
This is the most important question, and the one most wealth managers cannot answer honestly.
Post-exit founders do not need a portfolio manager. They built significant wealth without one. What they need is a single point of coordination for every financial decision in their lives — not just the assets sitting in a brokerage account.
In practice, that means being equipped to handle questions like:
- “My former business partner just showed me an investment opportunity. Does it make sense?”
- “I have an earnout provision from the sale. How do I structure and optimize it?”
- “I want to see my total net worth — not just the portfolio you manage, but my real estate, private investments, and the deal I co-invested in two years ago. Can you give me a complete picture?”
- “Can you manage the consolidation of all my year-end tax documents?”
- “I'm thinking about buying a property. Can you advise on the purchase and help me negotiate terms?”
These are not unusual requests. They are the questions that define what it actually means to serve a post-exit founder — and they represent the difference between an advisor who manages a brokerage account and a team that manages a life.
Before you enter a relationship, ask directly: “What is outside your scope?” An honest answer to that question tells you more than any amount of marketing material. If the answer is a version of “we focus on investment management,” you have your answer. If the answer is a detailed description of how they coordinate across your entire financial picture — taxes, real estate, outside investments, professional relationships, family governance — you may have found what you are looking for.
The Standard to Hold
The wealth management industry has done an effective job of presenting AUM fees, custodian relationships, and portfolio construction as the heart of what it does. For a founder navigating a liquidity event, those are table stakes — not differentiators.
What separates an advisor worth trusting at this moment is the quality of their pre-sale work, the depth of their professional network, their willingness to operate across custodians, and their genuine capacity to serve as a financial partner across every dimension of your life — not just the parts that generate a fee.
Ask the questions above before you sign anything. The answers will tell you everything the pitch deck won't.
