DecisionRules
|
DecisionRules is the decisioning platform build-first institutions rely on. It gives business teams no-code rule design and engineers full API control on a single platform where both collaborate on decision logic.Most enterprises run their decisions in one of two bad places: buried in application code, which only engineers can touch, or spreadacross spreadsheets no one trusts. DecisionRules replaces both with a managed decisioning platform. Business analysts author rules in a visual interface. Engineers integrate through a REST API, version everything in Git, and deploy through CI/CD pipelines. Ops teams monitor execution in production.The platform provides a full toolbox so every decision gets the right model. Decision Tables handle high-volume conditional logic. Decision Trees make branching visible. Decision Flows orchestrate multi-step processes. Scripting Rules cover custom calculations. Lookup Tables centralize reference data.Native AI Agents: turn unstructured documents into structured data. AI Agent is a native rule type that reads, reasons, and returns typed structured output — not a chatbot, not a bolt-on integration. It reads what Decision Tables cannot: contracts, medical reports, policy documents, emails. You define the schema, the AI fills it, and the result flows directly into the next rule downstream. Bring your own model: Google Gemini, OpenAI, Anthropic, Google Vertex AI, or Microsoft Foundry. Use different models for different rules. Enable Explainable AI for confidence scores and source fragments tied back to the original text. Enable caching to cut token costs to zero on repeated inputs. Alongside AI Agent, the embedded AI Assistant helps users create rules, generate test data, write functions, and summarize existing logic — measured ~60% faster rule authoring than building by hand.DecisionRules runs where your workloads run: public cloud, private managed cloud, or self-hosted on your own Kubernetes infrastructure with official Docker images and Helm charts. Integrations include Salesforce, Power Automate, Zapier, n8n, Azure, Oracle, Power BI, and data providers like Equifax, Experian, and LexisNexis.The platform processes 100M+ decisions daily for companies in 30+ countries across financial services, insurance, e-commerce, logistics, healthcare, and government. Recognized on G2 as a Leader in Decision Management Platforms, with badges for Best Estimated ROI and Fastest Implementation. Certified to SOC 2 and ISO 27001. | $1.8M / Seed / May 06, 2025 |
