There can often be good profit on mining new coins from an early stage before difficulty rises.
Does anybody know of any coins that haven't gone live yet, with gpu-friendly algorhythm?

The latest is Bitcoin Gold which at best has only very few days since has gone live but I am not sure about it and it is GPU-mineable only . The algorithm is the same as Zcash, the Equihash algorithm.
Anyway I would suggest you to do your own research as the developers of this coin are a bit shady in my opinion and there is a lot of confusion regarding this coin.
