Diego Fiori is a CTO and co-founder based in San Francisco with seven years of hands-on experience building and shipping AI-driven products. Trained as a physicist at EPFL and Politecnico di Torino, he blends rigorous quantitative thinking with practical machine learning engineering to take models from research to production across cloud environments. At Nebuly he leads efforts to simplify the complexity of LLM-powered products, while his past work at L2F shows end-to-end delivery of AutoML, NLP, and computer vision systems for healthcare, insurance, and logistics. He contributes to open-source AI tooling—most notably performance optimizations for Hugging Face models using ONNX, OpenVINO, and TensorRT—demonstrating a focus on inference acceleration and cross-runtime reliability. Curious and product-minded, Diego pairs low-level model optimization skills with a founder’s emphasis on real user behavior and deployable workflows.
