Going back to the phrase "software companies", the closest category-breakdown looks to be "Software Publishers", where the mean average [0] rises a bit to $149k. (I'm going to assume that the relative difference in means is similar to the difference in not-shown medians.)

You can see higher values, but I think they look suspiciously like generic labels slapped over large something-opolies such as Google ("Web Search Portals, Libraries, Archives, and Other Information Services", mean $215k) or Uber and Lyft ("Taxi and Limousine Service", mean $187k.)
