Kaluza Tech Stack

Energy intelligence platform orchestrating real-time grid and device decisions

Technology, Information and Internet London 501–1,000 employees Privately Held

Kaluza operates a Python + Kafka + Databricks platform that drives millions of real-time energy decisions across grids, homes, and electric vehicles. The tech stack—heavy on streaming (Kafka), cloud compute (AWS, Databricks), and orchestration (Kubernetes, ArgoCD, Knative)—reflects a company solving hard real-time coordination problems. Active hiring skews engineering and data-heavy, with 24 engineers and 8 data roles against 3 sales headcount, signaling a product-and-platform-first culture building infrastructure for energy retailers and grid operators rather than chasing transactional deals.
