Private Companies

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.

Lists of Private Companies


The URLs listed on this page aren't solely for private companies, but can list both public and private companies. Since private companies aren't required to publish as much data as public companies, you probably won't be able to find out as much about them.

Finding information on public companies in ABI/Inform Complete or Business Source Premier is not very difficult. The same is not true for private companies and/or divisions of public companies. Try to find Promega in the company search box of ABI/Inform or the Company Profile section of Business Source Premier. The results will be satisfactory but general. All this means is that you have to change your search strategy.

You can tighten the search for information on the private companies by changing the parameters of your search to look for mentions of the company name in the kind of documents that will dwell on more in depth information.
In ABI/Inform Complete, the search screen would look like this:


The problem with this type of text searching is that an article can mention the word Promega but the article might not have anything meaty to say about the company or yield very little information. 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. Also, you can select the Document type, which means you can eliminate seeing wire stories and brief news articles.

Search results box in ABI/Inform, using relevancy and limiting the Document Type:

You can do the same thing in Business Source Premier.

In Business Source Premier, the search screen defaults to showing the results by relevancy and the screen would look like this:

Local News


It doesn't matter if a firm is large or small; local companies are usually well-covered by the local press. Coverage is generally more in-depth and ongoing than what you may find in the national sources. Newspaper and periodical articles can provide extensive and varied types of information on companies--for example, historical background, new ventures, marketing campaigns, analyses of financial situations, and biographical profiles of key executives. Remember that news comes in all forms. Be sure to check radio and television news in addition to newspapers.

    There is an important technique that involves searching in newspapers, and especially databases that support an "at least" connector, like Lexis/Nexis.

Limiting your query in this manner practically ensures that the search yields articles that discuss the company.

  • Free web sites Secretaries of State
      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.
  • Free web sites 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).
