Cielara builds the Production World Model, a real-time digital twin of production infrastructure that simulates the impact of code and configuration changes before deployment to visualize blast radius, detect failures, and prevent outages. The platform runs changes against an exact copy of the live production environment, root-causes issues to specific commits or approvers, and enforces guardrails via GitHub CI integration. It targets engineering teams at leading F100 and F500 companies operating complex cloud workloads. The core technology features causal AI via Reasonara with a 125M token context window, six-layer causal graphs spanning intent, code, policy, infrastructure, and runtime, plus self-tuning simulation grounded in historical data and dependencies. Co-founded in 2024 by Hasibul Haque (CEO), Ryan Turner (CTO), Max Murshed (Head of AI), Gopi Ganapathy (GTM Leader), and Bowen Zhu (Lead, World Model Foundation). Headquartered in Redmond, WA.
