That was Seattle Business Computing whose product was bought out by 
Microsoft and became MS-DOS.  SBC basically made a quick and dirty
copy of Gary Kildall's CP/M on the cheap without really understanding
all the features they were copying.  But one of the things they copied
well were the file extensions including .EXE for executables.

CP/M itself was modelled after RT-11 which is where Kildall got the idea
for the .EXE extension.
