Complexio is the intelligence layer for enterprise AI. Our platform builds a connected understanding of how businesses actually operate — across people, processes, and systems.
Enterprises have invested heavily in AI platforms, copilots, and data infrastructure — yet daily work still runs on manual hand-offs and thousands of unseen tasks buried in emails, chats, and spreadsheets. Complexio closes that automation gap.
Our Event Knowledge Graph ingests structured and unstructured data to create a living map of how an organisation truly works — every task, interaction, and dependency. Our Context Broker unifies this knowledge across enterprise systems in real time, enabling our Orchestration layer and Enterprise Automator to discover, design, and execute workflows autonomously. Stevie, our conversational AI assistant, gives teams a natural way to query and act on that intelligence.
Complexio deploys securely within your infrastructure and integrates with the enterprise platforms you already run on — turning organisational knowledge into measurable business outcomes.
