Ben Segal works on inference performance at Parasail, an inference cloud that serves open-weight models on its own distributed GPU fleet. He focuses on the measurement and automation behind serving frontier models efficiently, and on the infrastructure that lets engineers and agents experiment on real hardware and real traffic without putting production at risk. Before Parasail, Ben spent about eight years at Swift Navigation, most recently as Senior Director of Engineering running Skylark, a global real-time service that corrects GPS to centimeter accuracy. He was also CTO of Navmatic, a micromobility safety startup acquired by Superpedestrian.
