Most enterprise AI projects stall between the proof of concept stage and actual deployment. The engineering backlog grows, timelines stretch, and business teams end up waiting months for something that was supposed to take weeks. Brussels-based Nexus is built to close that gap. The agentic AI platform raises €3.7 million ($4.3 million) in a seed round, backed by General Catalyst and Y Combinator, to accelerate enterprise adoption of production-ready AI agents.
The round also included Transpose Platform, Twenty Two Ventures, Phosphor Capital, and angel investors Gokul Rajaram, Raphael Schaad, and Jake Mintz.
Founded to Bridge the Gap:
Nexus was founded in 2024 by Assem Chammah, a former McKinsey consultant and aerospace engineer serving as CEO, and Shady Al Shoha, an AI engineer. The company operates from Brussels and San Francisco and serves enterprise customers across telecommunications, automotive, consulting, and technology sectors.
The core idea is straightforward. Nexus enables non-technical business teams to build and deploy autonomous AI agents without relying on engineering resources. The platform integrates across 4,000 or more enterprise systems including CRMs, ERPs, Slack, and Microsoft Teams, and is built with embedded governance and compliance from the start.
How the Platform Works:
Nexus takes an agent-first architecture and pairs it with white-glove implementation support. That means a dedicated team handles integration, rollout, training, and ongoing optimization alongside the client. The goal is to get an enterprise AI agent running in weeks rather than months.
Orange, the global telecommunications operator, deployed a customer onboarding agent through Nexus in four weeks. The result was a 50% increase in conversion rates and more than $6 million in annual lifetime value from a single agent. Tom Guisgand, AI Specialist at Orange, noted that the platform understood their needs through plain language descriptions and had a fully operational agent running within days. Customer satisfaction scores increased by more than 10 points.
Lambda.ai, an AI infrastructure company, also uses Nexus to run agents across sales and marketing functions. A single agent is saving hundreds to thousands of cumulative hours.
What the Funding Covers:
The €3.7 million will go toward product development, go-to-market expansion, and growing the implementation team. General Catalyst Managing Director Yuri Sagalov pointed to the speed of enterprise traction as the key investment signal. Nexus went from founding in 2024 to production deployments at major telecoms and technology companies within months.
The broader European enterprise AI agent market has seen sustained investment recently. Comparable rounds include Wonderful in Amsterdam, which raised €129.8 million, and several other platform players across Germany, the UK, and the Netherlands. Nexus stands out as one of the few Belgian companies operating at this level in the segment.
What This Means for Enterprise Teams:
For operators and founders evaluating agentic AI deployment, Nexus represents a model worth understanding. Non-technical teams can describe workflows in plain language and have an active agent running in production within weeks. The platform handles the integration complexity and compliance requirements that typically delay enterprise AI adoption.
Nexus is also a useful reference point for anyone tracking European startup funding rounds or following enterprise AI developments across the continent. The Brussels origin adds a meaningful data point for the Belgian tech ecosystem, which is still relatively underrepresented in the enterprise AI conversation compared to Western European neighbours.
The company’s approach of tying agent outcomes directly to measurable business results, like LTV growth and conversion rate improvements, reflects where enterprise buyers are in 2026. They want numbers, not demos.
