Does maddening and relentless hex from Warlock invocation benefit from Blood Curses of the Blood Hunter?

Sorry for the curiosity @matthewmercer but in discussion about blood hunter another question. Does maddening and relentless hex from warlock invocation benefit from blood curses of the blood hunter? Even if only you go profane soul? They would not, as blood curses are not Warlock hexes, I fear. 😉
