À propos

Adelean develops and deploys search engines in the broad sense of the term:

  • e-commerce engines

  • Enterprise Search engines

  • Conversational engines (like Perplexity or ChatGPT)

  • Dashboards for observability, monitoring and security

We develop two flagship products:

  • A2 : a data integration platform and a complete, innovative e-commerce search engine, compatible with Elasticsearch, OpenSearch and Apache Solr.

  • all.site : an enterprise and conversational search engine based on GenAI RAG (Retrieval-Augmented Generation) architecture, as well as a collaborative platform for sharing search engines - a true “GitHub for search engines”.

    Our team of developers, consultants, trainers and search engine experts is distributed across several locations. We have offices in Paris (Station F) and Versailles.
