Hello and thank you for your question. In some cases, there will be information in each State's website where you can view some information about license holders in that state. Some may just have company name, some may have registered address and limited contact information, but all will have some record of the license, of course. There are some companies who are "mining" this information and putting it in a central source. One of these sources is Cannabiz Media (https://cannabiz.media/) who currently are stating that they have 6291 cultivators in their system.
