www.shaving.ie gets my vote. Well-curated of mostly top drawer products. I've yet to see them beaten for price (delivered to the US).
Ah, we may mean something different by artisan companies? I am strictly interested in the small European soap companies, while you and the OP may think about American artisans.Although Shaving.ie and Connaught are top notch companies, the original poster asked if there was a vendor who sold a wide variety of artisan shave products.
Maggard Razors has carved out a nice niche for itself by offering a large selection of artisan products, along with the old chestnuts both matched by excellent service.
