As far I’m aware, he helped a that Gambian skeleton athlete set up his national federation. He also held a few combines/tryouts for his own NF, with a skeleton athlete attending an IBSF training camp earlier this season.
In many respects, he’s limited in what he can do. From my understanding, his sponsorships are just enough to cover his training, travel, competitions. He needs support from elsewhere to really get something serious off the ground.
Of course, it’s also hard to get other African nations interested in a sport when there’s no guarantee they’ll stand a real shot at the Olympics. Why would any sprinters, throwers, cyclists, lifters, etc. transition to bobsleigh/skeleton when there’s even less of a chance they’ll find some success there?
