insitro builds POSH automated wet-lab platform

The author details the engineering process behind building POSH, an automated wet-lab platform designed to generate high-fidelity human cellular data for AI drug discovery at insitro. The article explains how the team learned to measure, stabilize, and optimize physical and biological variables—such as temperature drift, fluid handling, and automated microscopy—to transform a noisy experimental process into a reliable data factory.
