Neuronetics, Inc.

A maker of non-invasive medical devices that treat mental health conditions, Neuronetics built the NeuroStar system, which uses focused magnetic pulses to stimulate areas of the brain involved in mood. Founded in 2003, it became the first company cleared by the FDA to use transcranial magnetic stimulation for depression that didn't respond to medication. The name blends "neuro" with "kinetics," hinting at its technology that applies moving magnetic fields to nudge underactive brain regions back into action.
