Inspiration
Construction procurement is reactive, fragmented, and heavily manual. We built Plexus to give procurement teams an Agentic AI based solution that continuously monitors risks, verifies evidence, and helps prevent costly project delays.
What it does
Plexus extracts procurement data from documents, Progress visualisation, and monitors global supply chain signals. It also predicts delivery risks using AI alongside simulations and recommends mitigation strategies, all while keeping humans in control of final decisions.
How we built it
We developed a multi-agent AI system with specialized agents for document intelligence, dependency validation, signal monitoring, evidence investigation, and probabilistic risk analysis. These agents are seamlessly connected through deterministic workflows as well as human approval gates.
Challenges we ran into
Balancing AI autonomy with enterprise trust was our biggest challenge. Because of this, we designed strict guardrails, evidence-backed reasoning, reproducible workflows, and deterministic validation to ensure absolute reliability.
Accomplishments that we're proud of
We are incredibly proud to have built a complete multi-agent procurement intelligence platform. Along the way, we successfully created an evidence-first, explainable AI system that features human oversight, and we designed a robust probabilistic delivery risk engine. Ultimately, we delivered a highly interactive, end-to-end working prototype.
What we learned
Enterprise AI succeeds through trustworthy system design rather than just powerful models. We realized that explainability, deterministic workflows, and human-in-the-loop decision-making are absolutely essential for real-world adoption.
What's next for Plexus: Smart Procurement
We're working toward production by integrating directly with ERP systems, expanding our supplier monitoring capabilities, and improving prediction accuracy through historical data. Our ultimate goal is to scale Plexus across the construction, manufacturing, and infrastructure procurement sectors.
