There are currently more then 3,000 firms in the database. However, we are very selective about the firms that we choose to include. The general criteria is that the firm must be a reputable firm actively closing deals in the marketplace. As such, we intentionally omit venture capital firms, angel investors, mezzanine funds, fund of funds and other extraneous noise from the data set. This is therefore a very clean, focused database appropriate for professional use.
