Tiny-C Associates incorporated in Holmdel, NJ, March 1978 [2]
"Tiny C" trademark application filed 1979, cancelled 1987 [3]
There was also a "Small C", see DDJ #45 (May 1980), "A Small C Compiler for the 8080s" by Ron Cain[4]. Cain references buying a copy of "the Tiny-C interpreter from Tiny-C Associates" and finding it too slow, so he bootstraps his own C compiler, writing it in C, compiles it on a UNIX system, then using it to compile itself to get the 8080 machine code.
See also DDJ #69 (July 1982) p. 66, "Small C for the 9900" by Matthew Halfant[5], porting Cain's compiler to another platform.
