Elastic's Growth & Acquisition Strategy
Elastic's strategy is to make Elasticsearch the retrieval layer for enterprise AI while consolidating observability and security tools onto the same platform. Recent moves include buying Jina AI (embeddings and rerankers) and Keep (AIOps alert management) in 2025, launching Elastic Workflows and Agent Builder for agentic automation, and releasing a serverless vector database in September 2026. The sales focus is on large customers: the >$100K ACV cohort grew by its largest-ever quarterly net addition in Q1 FY2027.
How Elastic Makes Money
Elastic is a B2B software company with an open-core model. Its core Elasticsearch and Kibana code is free to download, and the company makes money by selling paid subscriptions that add advanced features (machine learning, security analytics, AI assistants, enterprise support) and by running the software for customers as Elastic Cloud on AWS, Microsoft Azure and Google Cloud. Cloud customers pay largely based on consumption of compute and storage, so revenue grows as customers index and search more data. Subscriptions accounted for $1.634 billion of Elastic's $1.739 billion fiscal 2026 revenue; the rest came from professional services and training. Elastic packages the platform into three solutions: Search & AI (application search, RAG and vector search), Observability (logs, metrics, traces, APM) and Security (SIEM, XDR, endpoint protection).
