If you have spent any time looking at private investments, you have probably read a private placement memorandum (PPM), a confidential information memorandum (CIM), an “investor deck,” or a deal memo that summarizes the opportunity.
These documents can be helpful. They can also be deeply misleading, even when nobody is trying to commit fraud.
The problem is structural: most private deal materials are built to sell a story and manage liability, not to give you the clearest possible picture of risk, incentives, and what has to go right for the deal to work.
This article breaks down the most common ways private deal memos mislead investors, what to look for instead, and how to pressure test a deal without needing to be a full time analyst.
Important note: This is general educational content, not investment, legal, tax, or accounting advice. Private investments are speculative, illiquid, and involve a risk of total loss. Past performance does not predict future results. Consider your objectives and consult your own advisers before investing.
The uncomfortable truth: a deal memo is marketing dressed as analysis
In public markets, there are standardized disclosures, ongoing reporting, and generally more price transparency. In private markets, disclosure is negotiated, uneven, and often controlled by the party raising money. Even in well run offerings, the deal materials exist for three main reasons:
Raise capital by presenting a compelling narrative.
Frame risk in a way that is legally sufficient.
Create a paper trail showing investors received “disclosures.”
None of those goals is the same as “make the investor maximally informed.”
That is why it is common to see:
Pretty charts with thin assumptions.
A “base case” that quietly behaves like a best case.
Risks listed, but not quantified or connected to outcomes.
Comparables that flatter, not inform.
Terms explained in a way that glosses over who gets paid first.
This is not a moral judgment. It is just how capital raising works.
Your job as an investor is to translate the memo back into reality.
1) Projections are presented as if they are forecasts
Most private deal memos include some form of projected returns: revenue growth, margins, exit multiples, IRR, MOIC, payback periods, or distributions.
The misleading part is rarely the math. It is the confidence implied by the formatting.
A spreadsheet that outputs “22% net IRR” feels precise, even though it may be driven by a handful of optimistic inputs:
Growth rates that assume smooth execution.
Margins that assume pricing power.
Capital needs that assume no surprises.
Exit assumptions that assume a receptive market at the right time.
What to do instead
Ask for a sensitivity table that shows returns under stress:
What happens if revenue is 20% lower than plan?
What if the exit is delayed by 2 years?
What if margins are 300 bps lower?
What if refinancing costs are higher?
If the outcome goes from “great” to “barely okay” with small changes, the deal is fragile.
Also, watch for projection language that sounds like certainty:
“Expected” and “targeted” are often used in ways that readers interpret as “likely.”
A better framing is “illustrative” or “scenario based,” with clear downside cases.
2) “Total addressable market” slides substitute for real traction
A classic private market move is to start with a massive TAM (total addressable market), then show a tiny share capture that looks “conservative.”
This can mislead because the hard part is not the market size. The hard part is:
Distribution
Switching costs
Customer acquisition economics
Competition
Regulation
Time and capital required to scale
A $50B market does not make a company investable. It just means the story has room to sound big.
What to do instead
Look for evidence of pull, not just potential:
Cohort retention or repeat purchase behavior
Sales cycle length and conversion rates
Net revenue retention (for subscription businesses)
Gross margin trends
Customer concentration
Unit economics with clear definitions (and not just “LTV” hand waving)
If the memo highlights TAM but is vague on customer behavior, you are looking at a pitch, not proof.
3) Comparables are cherry-picked to flatter the valuation
Memos often include a comps slide: similar companies, similar assets, recent acquisitions, public market multiples.
Common issues:
Choosing a peer set that is higher quality than the target.
Using peak cycle multiples (especially in real estate or credit).
Mixing time periods, geographies, or business models.
Ignoring differences in leverage, margin profile, or growth.
What to do instead
Ask:
Why these comps and not others?
Are these comps at the same stage and risk level?
If this is a “roll up,” are the comps actually roll ups or mature platforms?
What multiple would apply in a recession or tighter credit environment?
If you are not given enough context to judge the comp set, treat it as marketing.
4) Key risks are disclosed, but not connected to outcomes
Most private deal materials include a “risk factors” section. It can run pages long. That can create a false sense of thoroughness.
The issue is that risk is often listed like a legal checklist:
“Competition may increase.”
“The manager may be unable to execute.”
“Economic conditions may deteriorate.”
True. But what does that mean for the investment?
What to do instead
Translate risks into specific questions:
If leasing is slower, what is the cash burn and what triggers a capital call?
If customer acquisition costs rise, does the model still work or does growth stall?
If rates stay high, can the deal refinance or does equity get impaired?
A good memo helps you see the causal chain from risk to cash flows to returns. Many do not.
5) The capital stack is explained, but the incentives are not
Private deals live and die by the fine print:
Fees
Promote / carried interest
Liquidation preferences
Dilution protections
Redemption rights
Covenants and triggers
Who controls major decisions
Memos often describe these terms accurately, but in a way that downplays how they shape outcomes.
For example:
A “2 and 20” style structure can be reasonable, but you need to know what the carry is calculated on, whether there is a preferred return, and whether there is a catch-up.
In venture, a liquidation preference can turn “a good exit” into “a bad outcome” for common equity holders.
In real estate, fees can meaningfully reduce investor returns even when a project “performs.”
What to do instead
Ask for a simple waterfall illustration with multiple exit values. If the sponsor cannot clearly show:
who gets paid first,
how fees accumulate,
and where the promote kicks in,
you are not ready to underwrite the deal.
6) “Alignment” is asserted instead of proven
You will often read: “The sponsor is aligned with investors.”
Sometimes this is true. Sometimes it is technically true but economically weak.
Examples:
The sponsor invests a small percentage relative to fee income.
The sponsor invests using borrowed money secured by management fees.
The sponsor has incentive to raise more capital even if the marginal deal quality declines.
What to do instead
Look for alignment in economics and behavior:
How much GP capital is at risk, in dollars, not just percentages?
How much revenue does the sponsor earn from fees regardless of performance?
What is the sponsor’s track record in down markets?
Are key personnel locked in, and what happens if they leave?
Alignment is not a sentence in a memo. It is a structure.
7) Track records are presented in ways that inflate competence
Private market performance is notoriously easy to “package”:
Gross returns instead of net of fees and expenses
Selected deals rather than the full portfolio
Unrealized marks treated like realized outcomes
IRR highlighted without showing MOIC and cash-on-cash
Vintage years that benefit from a unique market regime
This does not mean the sponsor is dishonest. It means incentives reward presentation.
What to do instead
Ask for:
Net performance (net of all fees and carry)
Full portfolio or fund level reporting, not just “case studies”
Realized versus unrealized breakdown
Loss ratios and write-offs, not just winners
The dispersion of outcomes (how often they lose money)
Also ask, “What did you learn from deals that went wrong?” If you get a polished non-answer, that is information.
8) Liquidity risk is minimized with friendly language
Private offerings often use language that sounds flexible:
“Target hold: 3 to 5 years”
“Potential early exits”
“Secondary opportunities may exist”
The reality is:
You may be locked in for longer than you expect.
Extensions are common.
Secondary sales can be restricted, discounted, or unavailable.
Even when there is a buyer, paperwork and approvals can take time.
What to do instead
Underwrite illiquidity as a core risk:
Assume you cannot sell when you want.
Assume the hold period extends.
Make sure you do not need that capital for near-term obligations.
Illiquidity is not just inconvenience. It can force bad decisions elsewhere in your portfolio.
It’s essential to understand the liquidity risks associated with private offerings and plan accordingly.
9) Conflicts of interest are disclosed, but not emphasized
Private market structures often create conflicts that are not obvious:
The sponsor may allocate deals among multiple funds.
The sponsor may use affiliated service providers.
The sponsor may earn fees on transactions (acquisitions, refinancings, dispositions).
The sponsor may manage both the borrower and the lender side in credit.
These conflicts can be managed well, but they should be scrutinized.
What to do instead
Ask:
What conflicts exist and how are they governed?
Is there an independent advisory committee?
Are affiliated fees capped or waived?
How is allocation handled between vehicles?
Good sponsors do not pretend conflicts do not exist. They explain how they are controlled. It's also worth considering options like continuation funds, which can help mitigate some of these issues by providing more clarity and control over fund allocations.
10) The memo creates “comfort” by being long
Length can feel like rigor. In practice, long memos often bury the key variables:
the true break-even,
the leverage sensitivity,
the dilution scenarios,
the fee load,
and the downside case.
A document can be 80 pages and still avoid the one chart that matters.
What to do instead
Try this exercise: summarize the deal on one page using only:
What you own (security, seniority, rights)
How it makes money (cash flows)
What can go wrong (top 5 risks tied to outcomes)
What you pay (all fees and carry)
What has to be true for it to work (3 to 5 “must be true” statements)
If you cannot do that after reading the memo, the memo did not do its job.
A practical checklist: questions that cut through most memos
When you want to get serious, these questions tend to separate “storytelling” from “underwriting”:
What is the single biggest driver of returns? Price, growth, leverage, multiple expansion, cost reduction, something else?
What is the base case assumption that feels most aggressive? And why?
What does failure look like? Not “lower returns,” but the actual operational or market path to loss.
Where does cash come from, and when? Timing matters, especially in leveraged deals.
How much can the sponsor earn if the deal is mediocre? Fee economics matter.
What happens in a recession scenario? Show numbers, not just words.
What are the gates and controls? Who can make what decisions and when?
What is the plan B if the exit window is shut? Refinancing? Hold longer? Sell at a discount?
If the sponsor answers these directly, that is a strong signal, even if you ultimately pass on the deal.
How a platform can help without replacing your judgment
Private investing does not need to be mysterious, but it does require process: organizing documents, comparing opportunities, tracking exposures across private and public holdings, and maintaining a record of what you reviewed and why.
That is one reason we built Braintrust. When you can research opportunities, attend educational webinars, review materials, and track your portfolio in one place, it becomes easier to invest with consistency rather than putting a finger in the air.
Just keep the hierarchy straight:
Tools help you get organized.
A good process helps you ask better questions.
Nothing replaces understanding the deal you own.
The bottom line
Most private deal memos mislead investors because they are built to raise capital, not to train you as an underwriter. They are optimized for persuasion and defensibility, which often means emphasizing upside, smoothing uncertainty, and burying the details that determine who wins and who gets paid.
If you want to protect yourself:
Treat projections as scenarios, not forecasts.
Demand downside analysis and sensitivity tables.
Follow the incentives through the fee stack and the waterfall.
Get clear on liquidity, conflicts, and control rights.
Reduce the deal to its core “must be true” statements.
Private markets can play a valuable role in a diversified portfolio, but only if you approach them with clear eyes and a repeatable framework.
Risk reminder: Private investments are illiquid, speculative, and may involve high fees, leverage, limited transparency, and complex tax and legal considerations. You can lose some or all of your invested capital. Always do your own due diligence and consider professional advice.
Frequently Asked Questions
What is a private placement memorandum (PPM) and how should I interpret it?
A private placement memorandum (PPM) is a document used in private investments to summarize an opportunity. However, it primarily serves to raise capital, manage legal liability, and create disclosure records rather than provide a fully transparent analysis. Investors should approach PPMs critically, understanding that they often present marketing narratives rather than objective risk assessments.
Why are projections in private deal memos often misleading?
Projections like IRR or revenue growth in private deal memos can seem precise but usually rely on optimistic assumptions such as smooth execution and favorable market conditions. They often lack sensitivity analyses showing how returns change under stress. Investors should request sensitivity tables and be cautious of language implying certainty, recognizing projections as illustrative scenarios rather than guaranteed forecasts.
How can total addressable market (TAM) slides be deceptive in private investment materials?
TAM slides highlight large potential markets but don't reflect the real challenges of capturing market share, including distribution difficulties, customer acquisition costs, competition, regulation, and scaling time. A large TAM alone doesn't confirm investability. Instead, investors should seek evidence of actual customer traction like retention rates, sales cycles, unit economics, and gross margin trends.
What issues arise with comparables used in private deal memos?
Comparables may be cherry-picked to flatter valuations by selecting higher-quality peers, using peak market multiples, mixing different geographies or business models, or ignoring differences in leverage and growth profiles. Investors should question why certain comps were chosen and whether they truly match the target's stage and risk level to avoid being misled by marketing tactics.
How are risks typically presented in private investment documents and what is the limitation?
Risks are often listed extensively as legal checklists without connecting them to specific investment outcomes. This approach can create a false sense of thoroughness while failing to clarify how each risk impacts returns or the probability of adverse events. Investors need to translate these disclosures into meaningful impact assessments for informed decision-making.
What steps can investors take to better evaluate private deal memos?
Investors should critically analyze projections by requesting sensitivity analyses, look beyond TAM to verify real customer traction metrics, scrutinize comparables for relevance and fairness, and connect disclosed risks to potential outcomes. Understanding that deal memos are marketing tools helps investors translate narratives back into realistic assessments of risk and reward before committing capital.
