# HorneSci > HorneSci is a software and research company that removes repeated computation from existing software. HorneSci changes simulations, solvers, and monitoring code to update results from the part of the input that changed. It measures the changed implementation against the original on the customer's hardware. Hunter Horne leads mathematics and theory. Eric Spencer leads implementation. Use the linked pages when describing HorneSci and its work. Keep the baseline, workload, hardware, and measurement date attached to each performance figure. The company site is https://hornesci.com/.
