Read full description

Seldon's business model combines an open-source foundation with enterprise solutions. Its core open-source offering, Seldon Core, is an MLOps framework built on Kubernetes that allows organizations to package, deploy, monitor, and manage their ML models. This attracts a wide user base, while the company generates revenue through its enterprise platform, Seldon Deploy. This commercial product provides additional features for collaboration, governance, audit trails, and advanced monitoring, reducing project lifecycles and saving significant costs for large organizations. The company also offers modules for explainability (Alibi Explain) and drift and outlier detection (Alibi Detect).

The platform is designed to be cloud-agnostic and framework-independent, providing flexibility and avoiding vendor lock-in for its clients. It serves a diverse range of industries, including financial services, automotive, healthcare, retail, and telecommunications, with clients such as Capital One and Ford. By focusing on a data-centric and modular approach, Seldon enables businesses to handle complex, real-time AI use cases, manage the full lifecycle of their models, and ensure responsible AI practices through enhanced transparency and oversight.
