How to Vet a Private Deal in 30 Minutes

This guide gives you a practical 30-minute process to vet a private deal quickly and consistently. It is not a substitute for legal, tax, or investment advice, and it is not a recommendation to buy or sell any security. It is a way to decide one of three things:

1. Pass (it fails basic checks or does not fit your goals)

2. Park (interesting, but you need more information)

3. Proceed (it merits deeper diligence)

If you are using an investment platform like Braintrust (https://www.braintrustinvest.com) to research, attend webinars, review materials, and track your portfolio across public and private holdings, this framework also helps you standardize how you evaluate opportunities across your watchlist.

Important risk reminder: Private investments may involve loss of principal, limited disclosures, limited liquidity, valuation uncertainty, capital calls (for some funds), and long holding periods. Past performance does not guarantee future results.

The 30-minute private deal vetting checklist (overview)

• Minute 0–3: Define the deal in one sentence + what you need it to do for your portfolio

• Minute 3–8: Confirm structure, terms, fees, and who controls the money

• Minute 8–15: Assess the business model and “why this wins” in plain English

• Minute 15–22: Evaluate people, incentives, and track record without hero worship

• Minute 22–27: Stress-test risks, downside, and liquidity realities

• Minute 27–30: Decide: Pass, Park, or Proceed. Then write your next-step questions

Let’s walk through each step.

Minute 0–3: Write the “one sentence” deal summary (and your own objective)

Before you judge a deal, force clarity.

1) Summarize the deal in one sentence

Examples:

• “A venture fund raising a new fund to invest in early-stage B2B software.”

• “A private credit fund offering loans secured by real estate.”

• “A growth-stage company raising a Series B to expand sales and marketing.”

If you cannot write a clean sentence, you do not understand it yet. That is a “Park” signal.

2) Decide what the deal is supposed to do for your portfolio

Private deals usually fall into a few portfolio roles:

• Growth (higher upside potential, typically higher risk and longer duration)

• Income (interest or distributions, still not guaranteed)

• Diversification (different drivers than public equities, but correlations can rise in stress)

• Inflation hedge (sometimes claimed, not automatic, depends on asset and leverage)

Write down your target role. If the deal does not match your role, it is okay to pass even if it is “high quality.”

Minute 3–8: Confirm the structure, terms, fees, and control points

This is where many investors lose time later. Get the basics right now.

3) What is it, exactly: fund, SPV, or direct company investment?

• Fund: A pooled vehicle with a manager making multiple investments. You are underwriting the manager and the strategy.

• SPV (special purpose vehicle): A pooled vehicle for a specific deal. You are underwriting both the deal and the SPV terms.

• Direct investment: You invest directly into the company. You are underwriting the company and the security terms.

Each comes with different documents, fees, and control mechanics.

4) Identify the security and where you sit in the stack

Ask: What am I buying?

• Common equity, preferred equity, SAFE, convertible note, senior debt, mezzanine debt, units in a fund, and so on.

If it is debt, ask:

• Is it secured or unsecured?

• What is the collateral?

• Where are you in priority if things go wrong?

If it is equity, ask:

• What rights come with the shares (information rights, pro-rata, liquidation preference)?

• Are there protections against dilution?

5) Read the “money terms” quickly

You are not doing full legal diligence in 30 minutes, but you can still spot red flags:

• Minimum investment and whether capital is called over time

• Fees (management fee, performance fee or carried interest, admin fees)

• Lockups and transfer restrictions

• Redemption policy (many private deals have none)

• Use of proceeds (for a company raise) or investment mandate (for a fund)

A common mistake is focusing on projected returns and ignoring fee drag and liquidity.

6) Confirm who controls the bank account and custody

For pooled vehicles, understand:

• Who is the manager or GP?

• Is there a third-party administrator?

• Are there audited financials (or an intention to audit)?

You are looking for a basic “institutional hygiene” signal. Lack of it is not automatically disqualifying, but it raises the diligence bar.

Minute 8–15: Understand the business model and why it might work

This is where you cut through storytelling.

7) Explain the revenue engine in plain language

Ask:

• Who pays?

• Why do they pay?

• How often do they pay?

• What would make them stop paying?

If you cannot answer these without buzzwords, Park it until you can.

8) Identify the real driver of outcomes

Most deals are driven by a small number of variables:

• Pricing power

• Customer acquisition efficiency

• Retention

• Gross margin

• Leverage and refinancing risk (for real estate and credit)

• Regulatory or reimbursement dynamics (healthcare, fintech)

• Cycle exposure (construction, discretionary spending)

Pick the top two drivers and note what would need to be true for those drivers to play out.

9) Check the valuation or entry price logic

You do not need a spreadsheet right now. You need sanity.

• For companies: What is the valuation? What is it based on (revenue multiple, comparable deals, prior round)?

• For real estate: What cap rate assumptions are being made? How sensitive is it to interest rates, occupancy, and expenses?

• For credit: What is the yield relative to default risk, duration, and recovery expectations?

If the pitch relies on “this is a rare chance” rather than a coherent pricing argument, treat that as a warning.

10) Look for disclosure of what could go wrong

Strong sponsors and companies can articulate risk clearly. If the materials are all upside and no trade-offs, assume the downside exists and is being under-discussed.

Minute 15–22: Evaluate people, incentives, and track record (without getting dazzled)

In private markets, execution and integrity matter a lot because you have less transparency and fewer exit options.

11) Who is the decision maker, and what is their edge?

Ask:

• What specific experience gives this team an advantage in sourcing, operating, or underwriting?

• Is the advantage durable, or is it a nice story?

12) Alignment: Are they financially motivated the way you want?

Look for:

• Meaningful GP commitment or insider ownership

• Fee structure that does not reward asset gathering more than performance

• Clear governance and reporting cadence

Be cautious when incentives encourage growth in assets under management at any cost, or when performance fees are paired with limited transparency.

13) Track record: What is real, what is marketing?

Track record in private markets can be messy. In 30 minutes, you are not verifying everything. You are checking whether the story is coherent and documented.

• Are results shown gross or net of fees?

• Are metrics realized or mostly unrealized marks?

• Are comparisons fair, or cherry-picked?

If track record claims are vague, you can Park and request supporting detail later.

Minute 22–27: Stress-test downside, liquidity, and concentration

This is the part most investors skip, then regret.

14) Liquidity and time horizon: When can you realistically get your money back?

Private investments often have:

• Multi-year holding periods

• No public market for resale

• Limited redemption windows (if any)

• Exit timing dependent on market conditions

Ask:

• What is the expected duration?

• What are the exit paths?

• What happens if markets freeze?

If you might need the capital in the next few years, be honest about that. Liquidity risk is not theoretical.

15) Downside case: Name three realistic ways this could disappoint

Examples:

• Growth slows, raising the next round becomes difficult, dilution increases

• Interest rates stay high, refinancing gets expensive, property cash flow compresses

• Defaults rise, recoveries are lower than modeled, and the fund gates redemptions

If the deal does not survive a basic downside narrative, it is probably a pass.

16) Concentration: What would this do to your portfolio risk?

Private deals can quietly concentrate your exposures:

• Too much in one sector (AI, real estate, crypto-adjacent fintech)

• Too much in one geography

• Too much in one stage (all early-stage venture)

• Too much in one manager

A practical rule: if a single private deal failing would materially change your financial plan, size is likely too large for your risk tolerance.

Minute 27–30: Decide Pass, Park, or Proceed (and write your question list)

At the end of 30 minutes, you are not trying to “be done.” You are trying to decide whether the deal deserves more of your time.

Use this simple decision rule

Pass if:

• You do not understand it clearly

• Fees, terms, or governance feel one-sided

• Liquidity is mismatched with your needs

• The downside is hard to define or obviously severe

• The pitch feels pressure-driven or light on risk disclosure

Park if:

• It might fit, but key facts are missing (financials, track record detail, audited statements, concentration limits)

• You need to compare it to alternatives

• You want to hear the sponsor answer questions live (for example, via a webinar)

Proceed if:

• You understand the structure and it fits your portfolio role

• Terms are reasonable for the risk

• The team’s edge and incentives make sense

• You can articulate both upside drivers and downside risks

• You are comfortable with the liquidity and time horizon

Write your “next-step” questions (copy/paste ready)

Here are solid, non-confrontational questions that surface quality quickly:

1. What are the top three risks you worry about most, and how do you mitigate them?

2. What reporting will investors receive, how often, and what metrics will be included?

3. How are valuations determined for unrealized positions (if applicable)?

4. What fees will investors pay at each layer (fund, SPV, admin), and are there any unusual expenses?

5. What is a realistic timeline for liquidity, and what are the most likely exit paths?

6. What assumptions matter most in your base case, and what happens if they are wrong?

These questions are also useful if you are reviewing archived materials later.

In making these decisions, it's crucial to understand the economic implications of your choices. For instance, this paper discusses various economic factors that could influence your decision-making process. Additionally, understanding past financial crises can provide valuable lessons for future investments. The insights from this FDIC speech could be beneficial in this regard.

A quick note on using platforms and workflow

A big part of “vetting in 30 minutes” is not just judgment. It is organization.

If you are evaluating multiple private opportunities over time, consider keeping a consistent record of:

• Deal summary, structure, fees, liquidity

• Your Pass/Park/Proceed decision and why

• Open questions and where you left off

Platforms like Braintrust can be helpful here because you can centralize research materials, attend live webinars, and track your portfolio holdings across public and private markets in one place. The key is to use a repeatable checklist so every deal is judged against the same standards.

In addition to utilizing such platforms, it's also essential to stay informed about the latest trends and insights in alternative investing. Resources like JPMorgan's Alternative Investing Insights can provide valuable information that aids in making informed investment decisions.
