When you’re raising capital for your business, you don’t have to choose between U.S. investors and international ones. Smart founders are using Regulation D and Regulation S together to cast a wider net and access global capital markets without the headaches of going public.
Here’s the thing: most business owners think they need to pick one or the other, but these two SEC regulations actually complement each other perfectly when raising capital. Regulation D handles your domestic fundraising, while Regulation S opens doors to investors outside the United States. Used together, they can significantly expand your funding opportunities.
Understanding the Geographic Split
The key difference between Regulation D and Regulation S comes down to geography. Think of it like this: Regulation D is your “home game” regulation for raising money from U.S. investors, while Regulation S is your “away game” regulation for international investors.
Regulation D governs private placements within the United States. Whether you’re selling equity to accredited investors in Texas or convertible notes to sophisticated investors in New York, Reg D is your go-to exemption. It lets you raise unlimited amounts of capital from qualified investors without registering with the SEC.
Regulation S, on the other hand, provides an exemption for securities offered and sold entirely outside U.S. borders. The SEC’s logic is simple: if no U.S. investors are involved and the offering happens offshore, why should U.S. securities laws be as strict?
Key Differences That Matter for Your Business
Investor Requirements
Under Regulation D, you’re dealing with accredited investor rules. For individual investors, that means they need either $1 million in net worth (excluding their primary residence) or $200,000 in annual income ($300,000 for couples). Entities need $5 million in assets. Also, SEC guidance issued in early 2025 stated anyone investing $200,000+ can be presumed to be accredited in most instances.
Regulation S doesn’t care about accreditation status. The only requirement is that investors must be “non-U.S. persons” – meaning they don’t live in the United States and aren’t U.S. citizens investing for U.S. accounts.
Marketing and Advertising Rules
This is where it gets interesting. Under Regulation D’s Rule 506(b), you cannot publicly advertise your offering. You’re limited to investors you already know or who come through existing business relationships. However, Rule 506(c) allows general solicitation and advertising – but then all investors must be accredited, and you must verify their accredited status.
With Regulation S, you can market internationally, but there’s a catch: your marketing cannot be accessible to U.S. investors. No placing ads in U.S. publications, no targeting U.S. residents on social media, and no marketing activities that could “condition” the U.S. market.
Resale Restrictions
Securities sold under Regulation D come with resale restrictions. Your investors typically can’t resell their shares for at least one year without registration or another exemption.
Regulation S securities have a “distribution compliance period” – usually 40 days for reporting companies or one year for non-reporting companies – during which the securities can’t flow back into the U.S. market.
How to Structure a Combined Offering
Here’s where the magic happens: the SEC has explicitly stated that a Regulation D offering won’t be “integrated” with a Regulation S offering. That means you can run both simultaneously without one affecting the exempt status of the other.
Let’s say you’re raising $2 million for your growing software company. You might structure it like this:
- U.S. Tranche (Reg D): $1.2 million from U.S. accredited investors
- International Tranche (Reg S): $800,000 from non-U.S. investors
Both offerings can use the same terms – same valuation, same type of security, same investor rights. The only difference is the regulatory framework governing each tranche.

Practical Implementation Steps
Filing Requirements
For your Regulation D offering, you’ll need to file Form D with the SEC within 15 days of your first sale. This form provides basic information about your offering – the amount you’re raising, who’s involved, and confirmation that you qualify for the exemption.
The Regulation S portion requires no SEC filings since it’s conducted entirely offshore. However, you may need to comply with securities laws in the countries where you’re marketing.
Documentation Strategy
You’ll likely use the same core offering documents for both tranches – your private placement memorandum, subscription agreement, and investor rights agreement. The key is adding specific language addressing the different regulatory requirements. Disclosure is critical and the primary document is the private placement memorandum – you do not want to run afoul of securities laws.
For Regulation D investors, include accreditation verification procedures and resale restriction legends. For Regulation S investors, include representations about non-U.S. person status and distribution compliance period restrictions.
Marketing Coordination
This requires careful coordination. If you’re using Rule 506(c) for general solicitation in the U.S., make sure your marketing doesn’t inadvertently reach international audiences who should be accessing your Regulation S materials instead.
Consider using different marketing channels entirely – U.S.-focused platforms for your Reg D offering and international platforms for your Reg S offering.
Compliance Considerations
Verification Requirements
Under Rule 506(c), if you’re doing general solicitation, you must take “reasonable steps” to verify accredited investor status. This might include reviewing tax returns, bank statements, or getting verification letters from CPAs or attorneys.
For Regulation S, you need to verify non-U.S. person status. This typically involves checking passports, foreign addresses, and getting representations that investors aren’t U.S. persons or investing for U.S. persons.
Ongoing Obligations
Both regulations create ongoing compliance obligations. Regulation D securities carry legends restricting resale, and you’ll need to monitor any secondary trading to ensure compliance.
Regulation S securities need monitoring during the distribution compliance period to ensure they don’t flow back to U.S. investors too early.

Strategic Advantages of the Combined Approach
Expanded Investor Base
The obvious benefit is access to a much larger pool of potential investors. Instead of limiting yourself to U.S. accredited investors (roughly 13% of U.S. households), you can also tap into international wealth.
Risk Diversification
Having investors from different geographic regions can provide stability. Economic downturns that affect U.S. investors might not impact your international investors the same way.
Competitive Positioning
Many of your competitors are probably only using Regulation D. By also utilizing Regulation S, you’re accessing capital sources they’re ignoring.
Common Pitfalls to Avoid
Integration Issues
While the SEC says Reg D and Reg S offerings won’t be integrated, you still need to be careful. Don’t use the same marketing materials for both, and maintain clear separation between the offerings.
Inadvertent U.S. Marketing
It’s easy to accidentally market your Regulation S offering to U.S. persons through digital advertising, social media, or website content. Use geo-blocking and careful targeting to avoid this.
Documentation Mistakes
Using the wrong form documents or failing to include proper legends and restrictions can jeopardize your exemptions. Each tranche needs appropriate documentation reflecting its specific regulatory requirements.
The Bottom Line for Growing Businesses
Combining Regulation D and Regulation S isn’t just for large companies or sophisticated issuers. If you’re raising significant capital and want to maximize your options, this dual-track approach makes sense.
The key is proper planning and execution. You need to understand both regulatory frameworks, structure your offering correctly, and maintain compliance throughout the process. While it’s more complex than a single-regulation offering, the expanded access to capital often justifies the additional effort.
Before moving forward with any capital raise, especially one involving international investors, consult with securities counsel who understands both Regulation D and Regulation S requirements. The compliance stakes are high, but the opportunities can be substantial for businesses ready to access global capital markets.
The combination of these two regulations gives growing companies unprecedented access to capital from both domestic and international sources – all while maintaining the flexibility and cost advantages of private placements over public offerings.
