Private companies do not sell shares on a publicly-traded stock exchange. They include partnerships, sole proprietorships, or corporations. They usually do not want to be public so that they can protect proprietary technologies, maintain unique marketing strategies, and control disclosure of their financials. Therefore, in order to find information about a private company, you need to determine likely sources where they would be found. In addition to directories and websites, those include industry publications, regional sources, trade shows and expert interviews.

What often happens is that an official of the company is quoted in an article. There are ways to handle this.
You can sort your results by date or relevancy. The default is date, but in this kind of search if you change the box to relevancy it will rank your searches by how many times (relevancy) the word you are searching for is mentioned in the article.

- Depending on the state in which it is registered, a private company may have to file annual reports with the Secretary of State, although the actual reports may or may not be available on the web. Secretary of State offices may provide articles of incorporation, UCC info, etc. Use this site to access each Secretary of State's web site.
- Securities and Exchange Commission
- When a company is private, but has plans to go public, they must file either a form S-1 or SB-2 with the SEC. The S-1's and SB-2's contain the full prospectus of a company at the time of filing, including financials, marketing, risk factors, competition, industry overview, executive compensation, and other information.
- Another reason a private company might have to file with the SEC is because they have issued public debt. In that case, they file registration statements (S1, S3, Prospectus), financials (10Q And 10K) and some material events (8K). It does not file a proxy and there are no insider/stakeholder filings (forms 3,4,5 and 13D).
