Angels, micro-funds and funds: what the rules say and what to ask
Founders talk about angels, micro-funds and funds as different investors. This article sets out what US securities rules say about each and what to ask.
This article is general information, not legal or financial advice. It was written on October 10, 2026, from the public sources listed on this page, and it does not describe any agreement with World Enterprise. Securities rules change and have exceptions, so confirm the current position with your own lawyer.
Founders often sort investors into angels, micro-funds and funds, and ask how each kind decides. No source cited here describes how any of them decides, so this article does not guess. What public sources do describe is the legal frame around every one of these investors: who counts as an accredited investor, which exemptions let a company sell them shares, and what each exemption asks of the company. Those rules shape what you must do whoever writes the check. For the practical side of choosing, read choosing the right first investors for a SaaS company.
The legal question behind the labels
A private company that sells shares must either register the offering or rely on an exemption. The SEC says every offer and sale of securities must either be registered under the Securities Act of 1933 or rely on an available exemption from registration. Section 4(a)(2) of the Securities Act exempts from registration transactions by an issuer not involving any public offering, and the SEC’s page on Rule 506(b) of Regulation D describes that rule as a safe harbor under Section 4(a)(2).
Regulation D leans on a defined term, the accredited investor. The rule defines it as a person who comes within a listed category, or whom the issuer reasonably believes comes within one, at the time of the sale. So the question to ask of any investor is not whether they call themselves an angel or a fund. It is which category, if any, they fall into.
How a person qualifies
The rule, in 17 CFR 230.501(a), lists the paths for an individual. A natural person qualifies if they have:
- an individual net worth, or joint net worth with a spouse or spousal equivalent, above $1,000,000, with the primary residence left out of the calculation under conditions the rule sets;
- individual income above $200,000 in each of the two most recent years, or joint income above $300,000 with a spouse or spousal equivalent, and a reasonable expectation of reaching the same level this year;
- one or more professional certifications, designations or credentials held in good standing, of the kind the rule describes.
The rule also lists any director, executive officer or general partner of the company selling the securities. That category matters to you: a founder who is a director or executive officer of their own company is covered by the rule’s text.
How an entity qualifies
An investment vehicle is an entity, and the rule gives entities their own paths. The table is a simplified reading of some of them. The rule carries conditions and exceptions that this table leaves out.
| Path | What the rule says |
|---|---|
| Large entity | An organization, corporation, trust, partnership or limited liability company, not formed for the specific purpose of acquiring the securities offered, with total assets above $5,000,000 |
| Owned by accredited investors | Any entity in which all of the equity owners are accredited investors |
| Entity with investments | An entity of a type not listed elsewhere, not formed for the specific purpose of acquiring the securities, owning investments above $5,000,000 |
| Regulated institutions | Banks, registered brokers and dealers, registered investment advisers, insurance companies, and a Small Business Investment Company licensed by the U.S. Small Business Administration, among others |
A vehicle formed for the specific purpose of acquiring the securities is treated differently. For counting purchasers under Regulation D, an entity organized for the specific purpose of acquiring the securities, and not accredited as an entity owned wholly by accredited investors, is looked through: each beneficial owner counts as a separate purchaser. Ask any investor that writes through a special-purpose vehicle how the vehicle qualifies.
What the exemption path asks of you
The exemption a company relies on sets who may invest and what the company must do.
- Rule 506(b). The company can raise an unlimited amount of money and can sell securities to an unlimited number of accredited investors, but may not sell to more than 35 non-accredited investors in any 90-calendar-day period. The rule allows no general solicitation or advertising to market the securities.
- Rule 506(c). The company may broadly solicit and generally advertise the offering, provided that all purchasers are accredited investors and the company takes reasonable steps to verify each purchaser’s accredited investor status.
- Disclosure. If the company sells to non-accredited investors under Rule 506(b), it must give them disclosure documents and the financial statement information that Rule 506 specifies.
- Form D. A company relying on Rule 504, Rule 506(b) or Rule 506(c) is required to file a notice on Form D within 15 days after the first sale of securities in the offering. The SEC’s Form D page says the date of first sale is the date on which the first investor is irrevocably contractually committed to invest, and that the SEC does not charge a filing fee for the notice.
- State law. Under Rule 506(c), the SEC says the states still have authority to require notice filings and collect state fees. Under Rule 504, a company must comply with state securities laws and regulations in the states where it offers or sells.
Rule 504 exempts from registration the offer and sale of up to $10 million of securities in a 12-month period. Which exemption fits your round is a question for counsel.
Who cannot use an exemption, and what follows from using one
Exemptions have limits on who may use them. The SEC’s Rule 504 page lists the companies that are not eligible: Exchange Act reporting companies, investment companies, companies that have no specific business plan or have indicated their plan is to engage in a merger or acquisition with an unidentified company or companies, and companies disqualified under the rule’s “bad actor” provisions. The SEC’s pages say Rule 506(b) and Rule 506(c) offerings are subject to bad actor disqualification provisions as well. Which people and roles those provisions cover is a question for your counsel, and the answer should come before you approach an investor, not after.
Purchasers in a Rule 506(b) offering or a Rule 506(c) offering receive restricted securities, the SEC says. What that means for an investor’s ability to sell is for counsel to explain. It is one more reason an investor may ask how and when they could exit.
The rules above set who may invest and which filings are required. They do not list what a careful investor weighs before writing a check, and none of the sources used here does either. Having your answers ready is the point of the investor readiness checklist and the data room guide.
Questions for the investor, and for your own counsel
- Which accredited investor category does this investor, or the vehicle they invest through, rely on, and who checks it?
- Is the offering under Rule 506(b), Rule 506(c) or another exemption, and does that change who I may talk to about it?
- What will the investor want to see before closing, and what will they want afterward?
- If the investor is a fund, what does the fund need to complete an investment, and who inside it decides?
- What filings do I owe, including a Form D and any state filings?
- Which of the questions in questions to ask your counsel before you sign apply here?
What this article cannot tell you
This article cannot tell you how any angel, micro-fund or fund decides. No source we fetched describes that, and the rules above set the limits of who may invest, not how an investor chooses. The terms angel and micro-fund are not defined in any source used here. The article covers United States federal rules only. It reads some, not all, of the paths in the accredited investor rule, and it omits conditions and later amendments. It does not cover state law, non-US investors or taxes. Nothing here is a recommendation of an investor, a lawyer or a platform.
