The law firm market
This category is the firm entity rather than an individual attorney — ranging from two-partner shops to firms with dozens of associates and a dedicated administrator. Larger firms have a managing partner or office administrator making infrastructure and vendor decisions on behalf of the whole practice, a very different buyer profile than a solo attorney managing their own spend.
Ontario holds 0.1% of the 69,688 law firm businesses MapLeads tracks nationwide; within CA, Los Angeles leads the vertical at 979.
