Monolith AI

Monolith AI is a British artificial-intelligence company founded in 2016 and headquartered in London, United Kingdom, as a spin-out from Imperial College London. Its self-learning platform helps engineers tackle the hardest-to-model physical problems by training machine-learning models on a team's existing physical-test and sensor data, then predicting how new designs will behave without re-running expensive tests — closing what the company calls the gap between simulation and reality. The platform includes tools for anomaly detection in test data, recommending which tests actually need to be run, and calibrating complex systems, and it is used in automotive, aerospace, and industrial research and development by organizations such as BMW, Mercedes-Benz, Honeywell, and BAE Systems. In 2025 Monolith was acquired by CoreWeave, the AI cloud-computing company. For mechanical engineers working on physical test and validation, Monolith is a leading AI-native tool.
