About
Seldon is a London-based ML model deployment and serving platform founded in 2014, built to solve the "last mile" problem in machine learning: taking trained models from data science notebooks and deploying them reliably into production environments at enterprise scale. The company grew out of the observation that the gap between a working ML model and a production ML system running safely in a Kubernetes cluster was enormous — requiring container orchestration, API management, monitoring, drift detection, and explainability tooling that most data science teams lacked the expertise to build. Seldon built this infrastructure as an open-source platform and commercial product.\n\nSeldon's core product is the Seldon Core open-source ML serving platform for Kubernetes, which enables data science teams to deploy any ML model — from scikit-learn and XGBoost to PyTorch and TensorFlow — as a scalable microservice with built-in monitoring and A/B testing capabilities. The commercial Seldon Deploy product adds an enterprise management layer with drift detection, concept drift alerting, outlier detection, and model governance features required for regulated industries. Seldon also offers explainability tooling through its Alibi open-source library, which generates human-interpretable explanations for model predictions — critical for compliance in financial services and healthcare.\n\nSeldon raised $39M in total funding, including a $20M Series B in 2023, and serves enterprise customers including PayPal, Johnson & Johnson, Audi, and Experian across financial services, automotive, healthcare, and retail sectors. The company competes with BentoML, MLflow, and cloud-native model serving services from AWS, Google, and Azure, differentiating through its Kubernetes-native architecture, open-source community, and enterprise-grade model monitoring and explainability capabilities.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
