Due diligence, in plain English.

7 MIN READ · LAST REVIEWED OCTOBER 2026

In short
  • Due diligence is everything you do to decide whether an opportunity deserves serious consideration.
  • Check three things: the issuer, the offering, and who controls the money.
  • A claim is not a fact until it has been verified, and a fact is only as good as the last time it was checked.

A short phrase for a long process

“Due diligence” sounds technical, but the idea is simple: before you commit money, you find out whether what you have been told is true, and whether the people involved can be trusted with your investment. In public markets, regulators, auditors and analysts do much of that work for you. In private offerings, much more of it falls to you.

Most investors were never taught how to do it. The good news is that you don’t need to become an expert. You need to know what to check, where to look, and when to ask for proof.

Check three things in every offering

1. The issuer: is it who it says it is?

Confirm the company exists and is in good standing in the state where it was formed. Find out who runs it, who owns it, and who is being paid to raise money for it. Search those names for past regulatory actions or disqualifications.

2. The offering: is it set up properly?

Most private offerings rely on an exemption such as Rule 506(b) or 506(c) and file a Form D with the SEC. Check that the filing exists and matches what you are being told: the exemption, the amount being raised, and the people named. Read the offering documents, especially the risks, the fees, and how and when you can get your money out.

3. The money: who controls it?

Ask where your money goes when you invest, whose name is on the account, and who can move it. Look for a dedicated account for the offering, a third-party administrator or outside accountant, and a cap table kept by someone other than the sponsor alone. Ask how often you will receive updates, and what they will include.

Where to look on your ownThe SEC’s EDGAR database shows Form D filings. Your state’s business registry shows good standing. FINRA BrokerCheck shows the history of brokers and firms. The SEC’s action lookup shows enforcement actions against individuals.

Questions to ask before you invest

  • Which exemption is this offering using, and when was the Form D filed?
  • Who are the directors, officers and managing members, and who is being paid to find investors?
  • Where will my money be held, and who can move it?
  • Who keeps the books and the cap table? Is a third party involved?
  • How often will I receive updates, and what will they show?
  • What happens if I want my money back early?
  • What has already been verified, by whom, and when?

Watch for pressure, not just problems

Urgency is a warning sign on its own. “Limited spots,” “closing Friday” and “guaranteed returns” are designed to stop you asking questions. A sponsor who is doing things the right way will be glad you asked, and will be able to show you.

Claims, facts and dates

Every offering tells a story, and every story is optimistic. A claim becomes a fact when it is verified. And because facts change after you invest, a verification is only as good as the last time it was performed. When you review an offering, ask not only “was this checked?” but “when, by whom, and when will it be checked again?”

HOW INVESTSECURE.ORG HELPS

We verify the Core 12, the twelve facts every investor should have before saying yes, or no, and show each one with how it was checked and the date of its latest review. Look for the badge, and open the record.

InvestSecure.org does not approve, rate, recommend or endorse any issuer, offering or person; a verification is not a recommendation to invest, and no fee depends on the outcome of an offering. Each point reports what was verified or remains unverified against specified sources as of its review date; no point establishes continuing truth or Rule 506 compliance. It does not assess quality, value or performance, or guarantee that a fact will remain true. Issuers remain solely responsible for their offerings, disclosures and compliance with securities laws.
