FAQ
- Which South Dakota companies raised money recently?

- What is a Form D?
- A short notice companies file with the SEC within 15 days after the first sale in an offering exempt from registration (most often Rule 506(b) or 506(c) private placements). It reports the amount offered and sold so far, the industry and the company's address.
- Does a Form D mean the company raised venture capital?
- Not always. It shows that securities were sold in an exempt offering: venture rounds, angel rounds and SAFEs, but also real estate syndications, debt and other private offerings. The amount sold is what the company reported, at the time of filing.
