The open map holds 27,121 open it and software companies in Illinois (Overture, August 2026). 23,732 of them publish a website, 26,404 a phone number, 22,453 a Facebook or Instagram page and 16,854 an email address. A place with none of those is on the map and out of reach, which is a fact about the market, not about the map.
