Founded in autumn 2013, the Alternate Company of the Month (ACOM) is an artwork contest in the vein of the Weekly Flag Challenge and Weekly Infobox Challenge, but is run on a monthly instead of a weekly basis. Instead of competing with fictional flags, maps or infoboxes from alternate histories, contestants compete with creating whole fictional companies/firms from alternate worlds.

The newest round is always at the top of this list. Each round is catalogued with a link to the announcement post, a link to the voting thread and links to the winner of the round and his fictional firm. Votes in some rounds resulted in a tie and therefore, two winners of a round.
