Private Company and Directory Information

Current Olin students, faculty and staff have access to restricted library internet resources. View Remote Access for more information.

Research Tip: It is difficult to find much of any information on private companies and almost impossible to obtain detailed financial information. For most private companies, the best you can hope for is to get total sales for the company, numbers of employees and when it was founded. In some cases, a local business publication (e.g. St. Louis Business Journal) has written an article on the company.
