I only know of a few impressive industrial uses of OCaml. However, those
are in exactly the sort of places where OCaml really shines, e.g. theorem
proving, program verification, and program transformation.
OCaml was used to do the C code generation for FFTW, an outstanding piece of
engineering which is pretty much the only cross-platform, high-performance
Fast Fourier Transform library that matters (it's essentially as fast as the
fastest hand-tuned libraries on all platforms). AirBus used Ocaml for a
program that verified the fly-by-wire software used in the A340 and A380--it
proved the absence of runtime errors like memory violations and overflows.
Microsoft used OCaml to implement a utility that developers used to detect
rule violations in Windows kernel-mode drivers. IBM used OCaml to convert
between DB2 and Oracle in the IBM Migration Toolkit.
You could write this stuff in Python, but the idea of doing it in OCaml is
that with some cleverness, you can leverage the state-of-the-art program
transformation and theorem-proving facilities that exist in the language
interpreter to do the heavy lifting, rather than implementing those
But for the 100 - epsilon percent of code that is not a theorem proving /
program manipulation problem, I would (and do) choose Python, Java, or C++
