    Rayven Reviews
    Top Pick
    Most organisations already have the data. The problem is it sits in disconnected systems - ERPs, databases, SCADA, IoT devices, files, and APIs - and nobody has built the layer that ties it all together in real-time. AI makes this worse. Models need clean, integrated, multi-source data to work. Most data environments are not ready. 95% of AI projects never reach production. Rayven builds that layer. It connects IT, OT, IoT, cloud systems, files, data streams, APIs, and proprietary protocols into a single managed data platform - then executes automation, AI models + agentic AI directly on live data. Five unified layers: integration (600+ connectors, bidirectional, real-time), data (processing, storage, AI-ready structuring), execution (automation, AI models, and agentic AI), presentation (custom apps, dashboards, and conversational interfaces), and security, governance + hosting (role-based access, audit trails, and data residency - built in as standard). What gets built on top: custom software, AI agents, predictive analytics, field applications, workflow automations, dashboards, and portals - all from one platform with no external tooling required. Serves businesses from growth-stage to enterprise across 24+ industries globally. Delivery: DIY, Done-For-You (fixed scope, fixed price, two to 12 weeks) + Hybrid. More than 600 pre-built connectors. Ten native AI capabilities. More than 240 deployments live. Rated 5/5 across more than 140 independent reviews.
