Why is so important to "know" who is behind TrueCrypt ? They publish the code and you can inspect it and build it yourself if you don't trust the provided binaries.
"There has been no known comprehensive review of the source code by a qualified cryptographer.[46][44] Thorough security code review and testing is hard, tedious, and painstaking work, and very few people have the skills to do it. There was, however, a functional evaluation of the deniability of hidden volumes in an earlier version of TrueCrypt by Schneier et al. that found security leaks." [1]
