Private placements — securities offerings sold without full SEC registration — rely on exemptions provided by Regulation D, and marketing them is governed by securities law most marketers never encounter. This article explains, in general educational terms, what Regulation D is, how its exemptions shape private-placement marketing, and what marketers need to understand. It is not legal advice; securities marketing requires qualified counsel.
What Regulation D provides
Securities offered to the public generally must be registered with the SEC — an expensive, demanding process.
Regulation D provides exemptions that allow companies to raise capital through
private placements without full registration, under defined conditions. It’s the framework most private capital-raising relies on.

The key exemptions under Regulation D for marketers are the Rule 506 exemptions:
Rule 506(b) permits raising unlimited capital from accredited investors plus a limited number of sophisticated non-accredited investors — but does
not permit general solicitation or advertising. Offerings rely on pre-existing relationships, and accredited status can generally be self-certified.
Rule 506(c) permits general solicitation and advertising — public marketing of the offering — but requires that all purchasers be accredited investors and that the issuer take reasonable steps to verify their accredited status.
The distinction matters enormously for marketers: under 506(b), you generally can’t advertise the offering publicly; under 506(c), you can, but with the accredited-only restriction and verification requirement. Which exemption an offering uses determines what marketing is permissible. This choice, and compliance with the chosen exemption, are legal decisions for the issuer and their securities counsel.
Common questions
What is a private placement?
A private placement is an offering of securities sold without full SEC registration, relying on an exemption such as those under Regulation D. Rather than a public registered offering, it’s a private capital raise to a defined set of investors under conditions that qualify for exemption. Private placements are common for startups, real estate deals, private funds, and other private capital raises. Because they’re unregistered, they operate under the specific conditions of their exemption — which governs, among other things, how they can be marketed.
What’s the difference between Rule 506(b) and 506(c) for marketing?
The central marketing difference is advertising. Rule 506(b) does not permit general solicitation or advertising — offerings rely on pre-existing relationships and can’t be publicly marketed — but allows some non-accredited sophisticated investors and generally permits self-certification of accredited status. Rule 506(c) permits general solicitation and advertising (public marketing) but requires all purchasers to be accredited and requires verification of their accredited status. So 506(c) allows marketing that 506(b) prohibits, in exchange for stricter investor requirements.
Can I advertise a private placement publicly?
Only under certain exemptions. Under Rule 506(c), general solicitation and advertising are permitted — so public marketing is allowed, subject to the accredited-only and verification requirements. Under Rule 506(b), general solicitation and advertising are
not permitted. So whether you can publicly advertise a private placement depends entirely on which exemption the offering relies on, which is a legal determination made by the issuer and their securities counsel. Advertising an offering that relies on 506(b) would jeopardize the exemption.
What does the verification requirement under 506(c) involve?
Under 506(c), issuers must take reasonable steps to verify that purchasers are accredited investors — they can’t simply rely on self-certification. Reasonable verification may involve reviewing financial documentation, obtaining confirmation from qualified third parties, or using verification services, with what’s “reasonable” depending on circumstances and SEC guidance. This requirement is what distinguishes 506(c) from 506(b)’s lighter self-certification, and satisfying it correctly is essential to maintaining the exemption — firmly a matter for securities counsel.
How does Regulation D affect how I use investor marketing data?
Investor data helps identify and reach potential investors, but Regulation D governs how offerings can be marketed and to whom. Under 506(b), marketing is constrained by the prohibition on general solicitation; under 506(c), marketing is permitted but purchasers must be verified accredited investors. So the exemption shapes what you can do with investor data in the context of an offering. Using the data must fit within the offering’s exemption framework, structured with securities counsel. This is general information, not legal advice.
What happens if a private placement violates Regulation D?
Losing the exemption is the central risk — if an offering fails to comply with its Regulation D exemption (for example, by improperly advertising a 506(b) offering, or failing to verify accredited status under 506(c)), the exemption can be lost, potentially turning the offering into an unregistered securities offering in violation of securities law. The consequences can be serious, including regulatory enforcement and liability. This high-stakes risk profile is why private-placement marketing demands qualified securities counsel throughout.
Where does the marketer’s role end and the lawyer’s begin?
Marketers can help identify and reach potential accredited-investor audiences and craft messaging appropriate to the chosen exemption. The selection of the exemption, the determination of what marketing is permissible under it, the verification of accredited status, and overall securities-law compliance are legal matters requiring securities counsel. The division is essentially: audience and messaging support sit with marketing; exemption choice, compliance, and verification sit with legal. Given the stakes, marketers should work closely with the issuer’s counsel throughout.
How this applies to your business
If you market private placements, the exemption framework governs everything — including whether you can advertise at all. Under Rule 506(b) you generally can’t publicly market the offering; under 506(c) you can, but only to verified accredited investors. Before any marketing, the offering’s exemption must be established by counsel, because it determines what marketing is permissible. Treat the exemption as the foundation your marketing is built on, not a detail to confirm later.
Work with qualified securities counsel throughout, and keep the marketer/lawyer division clear. Audience identification and exemption-appropriate messaging are marketing’s role; exemption selection, compliance, and accredited-status verification are legal. The verification requirement under 506(c) and the advertising prohibition under 506(b) are precisely where getting it wrong loses the exemption — squarely legal territory. This article is general educational information, not legal advice; consult a securities attorney for your situation.
Use accredited-investor data within the framework counsel establishes. Quality data helps identify and reach potential investors, but it operates inside the exemption’s constraints — it doesn’t substitute for securities-law compliance. Treat investor data as one input into a legally structured offering process, used in the manner the chosen exemption permits.
