There is no single way to invest in a private company. In the United States, an individual might buy securities in a Regulation D private placement, participate in a Regulation Crowdfunding or Regulation A offering, buy shares of a business development company (BDC) that owns private-company investments, or purchase an existing holder’s shares in a private secondary transaction. Each route has different eligibility rules, disclosures, fees, ownership rights, transfer restrictions and chances of finding a buyer.
Private-company investing can produce a total loss, and you may be unable to sell when you want. Treat the investment as long-term or indefinite, verify the current offering documents and rules, and commit only money you can afford to lose. This guide covers U.S. federal frameworks; state securities laws, your residence and the specific security can change the result.
What “investing in a private company” can mean
A private company is not required to have publicly traded shares on a national exchange. You can still gain economic exposure, but the instrument and legal relationship matter. You might own a company’s preferred stock, common stock, convertible note or other security; lend through a private debt offering; buy an interest in a pooled vehicle; or purchase shares from an existing holder. Those are not interchangeable investments.
The route also determines what information you receive. Public reporting companies generally file periodic reports under a standardized regime. Private offerings can provide a pitch deck, private placement memorandum, financial statements or a crowdfunding offering page, but the depth, audit status and continuing updates vary. An offering document, a Form D notice or a platform listing is not a finding that the investment is suitable, accurate or approved by the Securities and Exchange Commission (SEC).
#1 Best Overall
The SEC’s private-placement bulletin states: “Private placements, however, are not subject to some of the laws and rules designed to protect investors, such as the comprehensive disclosure requirements that apply to registered offerings.” Antifraud laws still apply, but recovering money after a fraudulent offering can be difficult or impossible.
Five U.S. routes to private-company exposure
| Route | Who may invest | What you own | Disclosure and limits | Liquidity considerations |
|---|---|---|---|---|
| Regulation D, Rule 506(b) | Unlimited accredited investors; up to 35 non-accredited investors if conditions are met | A security issued by the company or an affiliated issuer | No general solicitation; disclosure obligations depend on investor status and the offering | Usually restricted; resale requires an exemption and may face issuer or contractual limits |
| Regulation D, Rule 506(c) | Accredited investors only; issuer must take reasonable steps to verify status | A company security | General solicitation is permitted, but verification is required | Restricted securities and a potentially very small buyer pool |
| Regulation D, Rule 504 | Eligibility depends on the offering and applicable state and federal conditions | A company security | Eligible issuers can offer up to $10 million in a 12-month period under the SEC bulletin’s stated limit; conditions vary | Resale depends on the exemption, state rules, issuer terms and buyers |
| Regulation Crowdfunding | Individuals may participate, subject to investment limits and offering rules | The security specified in the offering, such as equity, debt or a similar instrument | Must use a registered broker-dealer or funding portal and provide specified company, financial, use-of-proceeds and risk information | Generally a one-year resale restriction with exceptions; an active market may never develop |
| Regulation A | Public investors can participate, subject to the tier and offering terms | The security described in the offering circular | Tier 1 and Tier 2 have different filing and ongoing-reporting requirements; SEC qualification is not approval | Securities may be less restricted, but finding a buyer without an exchange or active market can be difficult |
| Publicly traded BDC | Anyone able to buy the listed shares through a brokerage account | Shares of a portfolio investment vehicle, not direct shares of each private company | Exchange-listed filings and fund disclosures; fees, leverage, valuation and strategy affect results | Shares generally trade during market hours, but price can differ from portfolio value and may be volatile |
| Non-publicly traded BDC | Eligibility and minimums depend on the offering | Shares or interests in a non-listed BDC | Offering materials and periodic reports differ from listed BDCs | Repurchase windows may be limited or absent; there may be no routine exit |
| Private secondary transaction | Buyer and seller must satisfy applicable law and transaction requirements | An existing holder’s private-company security | Information may be limited; issuer, transfer agent and contract approvals can be required | A marketplace or bulletin board does not guarantee a buyer, execution or liquidity |
Regulation D private placements
Rule 506(b): a private, non-solicited offering
Rule 506(b) can accept an unlimited number of accredited investors and up to 35 non-accredited investors, provided the conditions of the exemption are met. The issuer generally cannot advertise the offering to the public. Non-accredited purchasers can trigger additional disclosure requirements, and an issuer can impose stricter standards than the legal minimum.
Ask for the exact security, capitalization information and all offering agreements. Preferred stock may have liquidation preferences, conversion rights or voting provisions that make it different from common stock. A convertible note can depend on a later financing, valuation cap, discount and maturity terms. A private loan can rank ahead of equity but still default.
Rule 506(c): public advertising with accredited-only sales
Rule 506(c) permits general solicitation, but every purchaser must be accredited and the issuer must take reasonable steps to verify that status. A self-certification checkbox is not necessarily enough. Verification may involve income documentation, net-worth evidence or a written confirmation from a qualified professional, depending on the process.
Rule 504: a capped offering route
The SEC’s Regulation D bulletin states that eligible issuers may offer up to $10 million in a 12-month period under Rule 504. State registration or qualification requirements and resale conditions can be important. Confirm the current limit and the issuer’s specific exemption because federal and state conditions can change.
Form D is a notice, not approval
Issuers commonly file Form D with the SEC after selling securities under Regulation D. The SEC’s wording is direct: “Form D does not represent SEC approval or registration.” A filing confirms that a notice was submitted; it does not verify the company’s projections, valuation, management or use of proceeds.

Do you have to be an accredited investor?
No. Accreditation is required for some offerings, not every private-company route. Regulation Crowdfunding permits public participation within its investment-limit framework, and Regulation A is designed for public offerings subject to its tier and conditions. Rule 506(b) can include a limited number of non-accredited investors. Rule 506(c), by contrast, is accredited-only.
Individual accredited-investor tests
The SEC’s accredited-investor bulletin lists these common individual tests:
- Income exceeding $200,000 individually, or $300,000 jointly with a spouse or spousal equivalent, in each of the prior two years, with a reasonable expectation of reaching that level in the current year.
- Net worth exceeding $1 million individually or jointly with a spouse or spousal equivalent, excluding the value of the primary residence.
- Certain financial-professional licenses in good standing, subject to the applicable category.
There are also entity categories. Meeting a threshold is a legal eligibility classification, not a recommendation, guarantee of sophistication or evidence that a particular investment is safe. Confirm the current rule text and the offering’s verification procedure before sending money.
How Regulation Crowdfunding works
Regulation Crowdfunding (Reg CF) allows qualifying companies to raise from the public through a registered broker-dealer or funding portal. The issuer must provide specified information about the business, offering, intended use of proceeds, risks and financial condition. The required information is more structured than an informal pitch, but it remains limited compared with a public reporting company’s disclosures. Financial statements may have different review or audit requirements depending on the offering and issuer history.
What to check before a Reg CF investment
- Open the official offering page. Confirm the issuer, intermediary, security type, price, target amount, maximum amount and deadline.
- Read the risk factors and financial statements. Look for cash burn, debt, related-party transactions, customer concentration and assumptions behind forecasts.
- Review the use of proceeds. Determine how much funds operations, marketing, repayment, salaries, acquisitions or fees.
- Understand your rights. Check voting, dividends, liquidation priority, conversion, information rights and dilution provisions.
- Calculate your limits and concentration. Apply the current investment-limit rules and consider the amount alongside your emergency savings and other speculative holdings.
- Plan for no sale. Crowdfunding securities generally cannot be resold for one year, subject to exceptions. Even after that period, a willing buyer may not exist.
Regulation A offerings
Regulation A has two tiers. The SEC bulletin states a $20 million maximum for Tier 1 and a $75 million maximum for Tier 2 in a 12-month period. Tier 2 generally carries more extensive reporting obligations and financial-statement requirements than Tier 1. Investors receive an offering circular describing the company and securities.
“Qualified” by the SEC means the offering met the applicable filing and qualification process; it does not mean the SEC approved the company’s accuracy, valuation or investment merits. Read the offering circular, audited or reviewed financial statements where provided, dilution terms and any resale provisions. A security can be legally resalable yet practically illiquid if no exchange or active market exists.
Buying exposure through a business development company
Publicly traded BDCs
A publicly traded BDC invests in debt and equity of small and medium-sized businesses, including private companies. Buying its listed shares gives you indirect exposure to that portfolio. You do not own a proportional direct share of each portfolio company, and you cannot choose which borrower or startup receives capital.
Evaluate the BDC as an investment vehicle: portfolio composition, credit quality, leverage, management fees, incentive fees, dividend policy, net asset value, valuation method and market-price history. Listed shares can be bought or sold during market hours, but the market price can trade above or below reported portfolio value and can move sharply with interest rates, credit conditions and investor sentiment.
Non-publicly traded BDCs
A non-publicly traded BDC may invest in similar assets but does not provide an exchange quotation. Repurchase offers can be limited to specified windows, capped at a percentage of shares, or unavailable. Valuations and disclosures follow the vehicle’s documents and regulatory requirements rather than continuous exchange pricing. Treat the exit as uncertain and read the repurchase policy before investing.

In a private secondary, an existing shareholder seeks a buyer instead of the company issuing new securities. The transaction may occur directly, through a broker or on a private marketplace. A listing or bulletin board is only an advertisement of potential interest; it does not guarantee a buyer, an executed trade, a fair price or an active market.
Conditions that can block a resale
- The security may be restricted and require a valid federal resale exemption.
- State securities laws can impose additional registration, notice or qualification requirements.
- The company may have a right of first refusal, board-approval requirement or transfer-agent process.
- Shareholder agreements can prohibit transfers to competitors or unapproved persons.
- The company may not provide current financial information to prospective buyers.
- There may be no buyers at the seller’s desired price, even when a platform displays indicative interest.
Before buying, obtain written confirmation of transfer procedures, legends, required consents, fees, settlement timing and the buyer’s ability to resell later. Ask whether the seller’s price reflects a recent financing, a different class of shares or a negotiated discount for illiquidity.
How to research a private-company investment
Use a repeatable diligence process rather than relying on exclusivity, celebrity endorsements or urgency. The SEC specifically highlights financial statements, management, competitors, use of proceeds, transfer restrictions and your capacity for total loss.
Rank #4
Company and market checks
- Request financial statements and determine whether they are audited, reviewed or unaudited.
- Reconcile revenue, margins, cash balance, debt, burn rate and runway with the company’s claims.
- Identify direct and indirect competitors and ask what prevents customers from switching.
- Review management backgrounds, prior operating results, litigation, bankruptcies and related-party arrangements.
- Test forecasts: identify the customer, pricing, hiring, regulatory and financing assumptions that must hold.
Security and deal checks
- Identify the exact class, number of securities, price per unit and ownership percentage on a fully diluted basis.
- Read liquidation preferences, seniority, conversion, anti-dilution, voting, redemption and information rights.
- Map existing debt and preferred classes that could receive proceeds before common shareholders.
- Confirm every fee, carried interest, placement charge, management fee and expense allocation.
- Ask when transfer restrictions might be lifted and what approvals a future sale requires.
Independent verification
Search available SEC filings in EDGAR, including Form D notices where relevant, and review state securities-regulator resources. A qualified lawyer or financial adviser can analyze an exemption, tax issue, contract or concentration problem specific to your situation. A professional’s involvement does not remove investment risk.

Liquidity: can you sell private-company stock?
Sometimes, but never assume it. “Liquidity” means the ability to convert a security to cash at a predictable price and reasonable speed. Private securities often fail one or more of those tests. Legal restrictions can prevent a sale; an issuer can withhold approval; and an interested buyer may never appear.
Why a sale can take longer than expected
- You identify a potential buyer and agree on a price.
- Counsel or the intermediary checks the federal exemption and state requirements.
- The issuer or transfer agent reviews the buyer, right-of-first-refusal terms and corporate approvals.
- Documents, signatures, legends and settlement instructions are completed.
- The transfer is recorded, which can take longer if company records are incomplete or the issuer is not cooperative.
Even a completed transfer can produce a lower price than the last financing round. A financing price may apply to a different security class, include strategic rights or reflect a larger, primary investment. Do not use it as a guaranteed exit valuation.

Set a total-loss limit
Assume the investment could become worthless. Keep emergency cash, insurance and near-term obligations outside speculative private investments. Do not borrow to invest in an asset that may not be saleable.
Limit concentration
One startup, sector, geography, founder or financing round can dominate results. Consider how the position interacts with employer stock, venture funds, public equities and other illiquid assets.
Match the time horizon
Use a time horizon that tolerates years without distributions or a sale. A planned tuition payment, home purchase or retirement withdrawal is a poor match for a security with uncertain resale.

Watch for pressure tactics
High-pressure deadlines, claims of guaranteed returns, secrecy demands and “exclusive” access are reasons to slow down. Ask for written answers and independently verify material claims. A polished presentation does not substitute for evidence.
A practical decision framework
| Question | If the answer is “yes” | If the answer is “no” |
|---|---|---|
| Can I lose all of this money without impairing essential goals? | Continue to diligence size and concentration. | Do not invest this amount. |
| Do I understand the security’s priority and rights? | Compare those rights with the price and valuation. | Pause until the documents are clear. |
| Can I hold indefinitely? | Assess whether the potential return justifies illiquidity. | Prefer an investment with a dependable exit. |
| Can I verify the issuer, management and financial claims? | Document the evidence and remaining uncertainties. | Treat the information gap as a material risk. |
| Are the fees, leverage and conflicts understandable? | Compare the net outcome with alternatives. | Request clarification or decline. |
| Do I satisfy the route’s eligibility and transfer rules? | Complete required verification and retain records. | Do not attempt to bypass the restriction. |
Costs, taxes and recordkeeping
The security’s stated price is not the complete cost. Identify platform or placement fees, legal and transfer-agent charges, fund management and incentive fees, borrowing costs, and expenses charged to a BDC or other vehicle. For a secondary purchase, ask who pays transaction costs and whether the quoted price is net of fees.
Tax treatment depends on the instrument, holding period, entity structure, distributions, losses and your jurisdiction. Keep subscription agreements, capital-account statements, valuation notices, confirmations, Forms K-1 or 1099 where issued, and records of every fee. Obtain tax advice for your facts rather than assuming that a private-company loss or gain will receive a particular treatment.

U.S. scope and changing rules
The frameworks described here are U.S. federal securities concepts. State requirements can apply, especially when securities are resold. SEC bulletins and offering limits can be updated, and an issuer’s documents control the specific transaction. The Regulation D Investor Bulletin was updated September 21, 2026; the cited Regulation Crowdfunding bulletin is dated October 14, 2022, while the accredited-investor and Regulation A bulletins are dated April 14, 2021. Recheck the operative SEC rule text, current limits and issuer disclosures before investing.
For broad background, Private Capital: The Complete Guide to Private Markets Investing from Wiley-VCH can help explain private-markets concepts, but it is not a substitute for current legal documents, tax advice or individualized investment advice.
