Securities attorney here -- I see a lot of confusion about Reg D 506(b) vs 506(c) in these threads, so let me lay out the practical differences that matter for founders.
506(b) -- the "quiet" offering:
- You CANNOT do general solicitation or advertising. This means no posting on social media, no public pitch events, no AngelList syndicate listings that are publicly visible.
- You can raise from an unlimited number of accredited investors PLUS up to 35 non-accredited "sophisticated" investors
- You must have a pre-existing, substantive relationship with every investor BEFORE offering securities
- Non-accredited investors must receive detailed disclosure documents similar to what you would file in a registered offering
506(c) -- the "advertise freely" offering:
- You CAN do general solicitation -- post on LinkedIn, run ads, pitch at public demo days
- BUT every single investor must be verified as accredited through reasonable steps (tax returns, bank statements, CPA letter, or a third-party verification service like Verify Investor or Parallel Markets)
- No non-accredited investors allowed, period
The biggest compliance trap I see with 506(b): founders who attend a public startup event, pitch their company, and then accept investment from someone they met at the event. That is general solicitation followed by a sale, which violates 506(b). You either need to have the relationship before the pitch, or switch to 506(c) and verify accreditation.
For most early-stage founders raising from friends, family, and angel investors they already know, 506(b) is simpler and cheaper. If you want to cast a wider net and do not mind the verification costs (usually 50-200 dollars per investor through a third-party service), 506(c) gives you more flexibility. Either way, file a Form D with the SEC within 15 days of the first sale of securities.
