I wish I know if Tantan is the manufacturer of this frame, or just a broker.
Maybe Patrick can have the information ?
Tantan is a big animal, and their reputation is not great because of that. They sell a LOT of frames. Airwolf frames are dog $hit, for simplicity. If you have to choose between the 2, 100% of the time, go w Tantan.
Tantan isn't a broker, they make frames, afaik. It might be a carbonda situation where carbonda does make frames but it's probably the mothership behind it called - the name escapes me - that actually makes them, but it doesnt make carbonda a broker.
Velobuild is a broker.
Airwolf frames are crap, in the sense that the probability that you have significant problems with your frame is so high that you really have to want to make your life difficult AND give your money to people who give zero fucks to work with them. I do love their cockpits though, which tells me, they source stuff all over the place. Maybe they make the frames and source the cockpits.
