Titan was the only sub they actually designed and built by themselves.
Antipodes was purchased. Cyclops was purchased and refitted - meaning someone else actually designed and built the pressure hull. They did retrofit it so it could be steered with a wireless gaming controller, though!
More seriously, I think they have a couple of other submersibles rated for much shallower depths, one they built and one they bought, IIRC.
I wouldn’t even trust the one they bought, given their attitude to safety.
“This sub is only rated for 1km? That’s only a suggestion.”

Still just the one Logitech controller, though, so no dice.
