Extropic scores C on the Alion truth index (A is best, E worst), measured over 10 open roles re-checked against its own hiring board: 70% look like ghost listings, 0% have gone stale and 0% are the same role posted again. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
Extropic is building thermodynamic computing hardware that performs probabilistic sampling in physics rather than in software. Founded in 2022 by former Google quantum computing researchers, it targets generative models that are natively stochastic. The company published its first prototype chips and an open simulation stack.
