It looks like to me that it has the same people behind it as the Bitcoin Unlimited, but it's only a couple months old:

They want to do a 8 MB hardfork on August 1
Bitcoin Cash provides much needed relief to users with an immediate increase of the block size limit to 8MB.
On August 1st 2017, We the People will breathe new life into Bitcoin.
I wonder of "We the People", as in 40 billion $, will trust a 3 month old website and a lame copycat of the Bitcoin Core software. On the contrary, considering it launched at the full difficulty of the legacy Bitcoin chain, managed to have essentially volunteer miners find even its first post-fork block (some call it the Exodus Block), has since demonstrated that it's new downward difficulty adjusting mechanism works as designed, and is now clearly functional enough to survive to the next standard difficulty adjustment despite its miners still operating at a cost deficit seems to me to be a quite good showing so far. Morever, in the midst of being bombed by the Nothing-But-Core and dump free coins crowds, it's still holding up as the fourth largest cryptocurrency by market cap, despite being less than four days old. I'd say that's hardly a joke.
Furthermore, it's clearly proved the Blockstream and Core contentions that a hard fork would be disastrous, or must take forever to plan were always bald-faced lies.
Going forward, it's going to function as a hedge against possible problems with SegWit and it's unnecessary, Rube Goldgerg-ian complexity, as well as insurance that on-chain scaling will continue regardless of whether the 2x part of SegWit2x ever activates.
Lastly, even in its nascent state, it's demonstrating what actual developer decentralization can look like in the Bitcoin space, with four different development teams, each fielding its own compatible client.
