Nexus, a Brussels-founded AI agent deployment platform backed by Y Combinator, has secured $4.3 million in a seed round led by General Catalyst, with contributions from Y Combinator, Transpose Platform, Twenty Two Ventures, and Phosphor Capital. Angel investors Gokul Rajaram, Raphael Schaad, and Jake Mintz also participated.
Founded in 2024 by CEO Assem Chammah, an aerospace engineer and former McKinsey consultant, and AI engineer Shady Al Shoha, Nexus operates in Brussels and San Francisco. The startup addresses a common issue in enterprise technology: AI projects often fail not due to the AI itself but due to lengthy engineering backlogs between business teams’ ideas and deployment.
Nexus proposes that non-technical teams can describe their needs in plain language to deploy an agent within weeks, integrating with over 4,000 systems like CRM, ERP, Slack, Teams, and custom APIs, with built-in governance and compliance. The platform is already in use at Orange, where a customer onboarding agent was deployed in four weeks, boosting conversion rates by 50% and generating over $6 million in annual LTV.
Lambda.ai, an AI infrastructure firm, utilizes Nexus for its sales and marketing functions, and Proximus Global is among its enterprise clients. Nexus combines its self-service platform with white-glove implementation support, offering engineering and enablement teams for integration, rollout, training, and optimization.
Yuri Sagalov, Managing Director at General Catalyst, noted Nexus’s rapid enterprise traction, achieving production deployments at major companies just months after its founding in 2024. The funding will support product development, market expansion, and team growth.
In a crowded agentic AI deployment space, Nexus stands out with its YC background, General Catalyst support, and successful deployments at major enterprises, positioning it as a credible early-stage contender.
