There are several Tangram companies out there. The company you're thinking of is now called Modelfox (https://www.modelfox.dev/), but used to own the https://tangram.dev domain.
There is also Tangram Vision (https://www.tangramvision.com) which is a startup focused on multi-sensor calibration and sensor-fusion. They have been around since 2020, while the other Tangram's out there are relatively newer.
This company (https://tangram.dev) is a different entity entirely.
