Linkup builds a production-grade web search API for AI systems, letting LLM applications and autonomous agents retrieve current, cited information from the web instead of relying on static training data. The API is offered as a hosted cloud service, as a private access-controlled index over proprietary data, or run inside a customer's own cloud. Founded in 2024 by Philippe Mizrahi, Denis Charrier and Boris Toledano, the company serves hundreds of customers including Databricks, McKinsey, Cohere, EY, KPMG, Legora and Artisan.
What sets it apart
A search index built for machine consumption rather than human browsing - granular, precise passages with sub-second latency, top-ranked accuracy on the SimpleQA factual benchmark, and an SLA-backed 99.9% uptime, plus deployment options (private index, bring-your-own-cloud) that let regulated customers keep proprietary data in place.
A web search API accessible from a single HTTP endpoint that returns sourced, cited answers and full-text snippets from a purpose-built index, designed to ground LLMs and agents in real-time factual data.
