Thermavance logo imagePromethient was founded in 2012 by Charles Cauchy, an expert in the field of solid state heating and cooling using thermoelectric devices.

Promethient’s solid state heating and cooling technology is marketed under the Thermavance brand name.

Promethient’s Thermavance system is said to allow for the cooling and heating of a person via direct thermal conduction. Heat is pumped from the person, cooling them, or heat is pumped to the person, warming them. Thermavance is a patent pending system. Thermavance combines solid state heat pumping provided by a thermoelectric device and couples it with thermally conductive, flexible and lightweight graphene.

In March 2018, Promethient developed a graphene-enhanced seat warmer technology that it says is more efficient and durable than similar available systems.
