Nexus is an agentic AI platform that lets non-technical teams in large organizations build and deploy production-ready AI agents without engineers. The platform combines natural-language configuration, a visual workflow builder, and AI-powered decision-making, and integrates across more than 4,000 enterprise systems including CRM, ERP, Slack, and Microsoft Teams. This lets business teams build agents that execute complete workflows end-to-end in days rather than months. Nexus operates from Brussels and San Francisco and was part of Y Combinator's Fall 2025 batch.
