Algolia

“Algolia's core value is low-latency, globally distributed search infrastructure with a tuning UI — not the intelligence layer. An LLM can write the query logic but can't replace the sub-10ms index serving at scale, the SDKs embedded in thousands of production apps, or the decade of developer trust. The coordination moat is real: Algolia sits between your data pipeline, your frontend, and your analytics, and ripping it out is painful. But LLMs are eating the 'relevance tuning' and 'query understanding' layers fast, which were Algolia's premium upsell.”
