About Us
Combining AI and domain knowledge to enable circular resource management
Era of Change
We live in an era of systemic structural change.
Artificial Intelligence (AI) is reshaping industries, economies are reordering, security alliances are shifting, and climate change is multiplying interconnected economic, environmental and security risks.
In this uncertain time of change, the need to secure strategic water, energy and food resources – the resources of life – is critical.
Philosophy
In the Linear Economy, we manage water like we manage oil – as a Finite Stock. This fuels a scarcity mindset, and the win-lose paradigm that divides our world.
In the Circular Economy, we manage water and energy as renewable Circular Flows.
This fuels an abundance mindset, and the win-win cooperation required to reshape sustainable economic models of the future.
Fragile Linear Economy
Depletes resources, ecosystems and trust
• Efficiency depends on centralisation
• Long vulnerable value chains
• Win-Lose competition
Resilient Circular Economy
Renews resources, ecosystems and trust
• AI enables efficient decentralisation
• Resilient local value chains
• Win-Win cooperation
Adaptive Circular Solutions
With a primary focus on water and energy, Nexus combines AI-driven advanced process control (APC) with domain knowledge to create efficiencies, reduce waste, and enable closed-loop circular resource management.
Our solutions adapt complex, highly variable processes in real or near real-time – optimising existing infrastructure and enabling the development of efficient and resilient new infrastructure.
Our business and approach is centered on three core pillars:
Our business and approach is centered on three core pillars:
1. Knowledge
Core knowledge in water within the water-energy-food nexus
2. Data Platform
Adaptive data management and control
3. Innovation
Rapid solutions development, bridging old & new systems
LEADERSHIP TEAM
Our leadership team combines global experience in technology and financial innovation, strategic resource management, and the nexus between water, energy, food and security.
