K. Alataris built his career as a hands-on founder rather than a typical investor, starting Nevro and later Nēsos by digging into the actual science, like testing new stimulation frequencies and studying single-cell recordings with Mayo and Stanford to see how signals travel to the brain. That hands-on approach traces back to his academic training in nonlinear neural networks and brain plasticity under Vasilis Marmarelis, and it still shows up in how he talks about chronic pain today, describing it as a kind of network and memory effect in the brain that devices might be able to retrain.
