About Nexai.net

In 2017, while leading the AI Lab at Sopra Steria in Brussels, my friend Mickael Thumerel and I built the first version of Democrite, a multi-agent framework—my specialty. By 2022, we decided to rebuild it entirely from scratch. We initially planned to launch our own company, but eventually, our journey led us to join the Amexio group.

On December 22, 2024, Mickael passed away after a sudden, tragic illness. Six months later, I stepped down from my role at Amexio.

It took me two years to get my head back into Democrite. Mickael was by far the better developer between us, but with the help of Opus 5.5, I’ve finally reclaimed the codebase and made it my own again.

Nexai.net was our shared dream. I’ve shed a few quiet tears while coding it, but Nexai.net isn't just a project—it's a continuation of what we built together.

I miss you, Micka. I love you, my friend.

What was Nexai.net ?

Redefining Enterprise Intelligence & Autonomous Systems

We bridge cutting-edge artificial intelligence, systems thinking, and decision science to build resilient, high-performance enterprise platforms. By integrating full-stack AI methodologies with intelligence tradecraft and cognitive science, we deliver technology designed for complex, dynamic environments.

Our Projects:

Démocrite | Orleans-Powered Multi-Agent Framework

Démocrite is an open-source, highly scalable multi-agent framework built on top of Microsoft Orleans. Designed for distributed systems, it leverages the virtual actor model to manage massive agent orchestration, asynchronous state handling, and robust fault tolerance. Démocrite provides the foundational backbone for building autonomous, reactive, and highly concurrent AI architectures.

SyDE | Systemic Decision Empowerment Platform

SyDE is an advanced platform engineered for enterprise intelligence, strategic insight, and operational decision-making. By synthesizing multi-source data, complex system modeling, and contextual intelligence, SyDE empowers organizations to navigate uncertainty, detect emerging patterns, and make high-stakes decisions with confidence.

Our Paradigm :

Full-Stack AI Integration
We reject the monolithic reliance on a single AI paradigm. True intelligence requires a hybrid approach:
Symbolic AI & Knowledge Representation for deterministic logic and auditable rules.

• Deep Learning & Connectionist AI for pattern recognition and perception.
• Cybernetics & Systems Theory for feedback loops and adaptive control.
• Operations Research & Simulation for optimization and scenario stress-testing.

Multi-Disciplinary Fusion

Cutting-edge AI does not exist in a vacuum. We enhance standard agentic frameworks, Large Language Models (LLMs), and modern data science by integrating methodologies from:
Intelligence & OSINT Tradecraft: Structuring unstructured threat landscapes, counter-bias methodologies, and signal extraction.

Psychology & Cognitive Neuroscience: Modeling behavioral dynamics, decision-making biases, and human-agent interaction.

Open-Source Commercial Strategy

We believe foundational tools should be open, inspectable, and community-driven. Our business model is anchored in Open Source core technologies:
Transparency & Control: Full auditability without vendor lock-in.

Enterprise Offerings: Tailored integration, specialized modules, dedicated support, and enterprise-grade deployment architectures around our core open frameworks.
