Elastic
“Elastic spent a decade building the world's most beloved open-source search engine, then successfully monetized it into a $8B public company that enterprises actually pay for — cloud hosting, security features, and support that keeps Elasticsearch running when your Black Friday traffic spikes. The beautiful irony is that their customer infrastructure becomes more valuable as AI agents proliferate, not less: every ChatGPT clone, every RAG pipeline, every 'context-aware agent' needs exactly what Elastic built — fast vector search, real-time data ingestion, and the ability to find needles in haystacks at millisecond latency.”
