List time on the internet. A new list in the past couple of days lists the best companies to work for in each state. I want to know who does these lists. Arkansas listed Walmart, New Hampshire is Planet Fitness, Nebraska is Berkshire Hathaway and IowaâĻ.IDX. I had no idea what IDX was, after looking it up itâs some sort of AI medical diagnostics. It says they have 1 â 50 employees and have pulled in less than 1 million dollars per year in Revenue. Maybe Iâm looking at the wrong IDX but If itâs correct I donât know what makes that the best company in Iowa. Check out the full list HERE!
