Jina AI

The company's main offerings include embeddings, rerankers, and small language models (SLMs). Its products are designed to create sophisticated search and retrieval-augmented generation (RAG) systems. Jina AI provides tools like `jina-embeddings-v2` which supports a long context length of 8,192 tokens for tasks such as text classification and summarization. The firm has also developed a suite of open-source projects including Jina, a cloud-native neural search framework; DocArray, a data structure for unstructured data; and Finetuner, for refining deep neural networks. This commitment to open-source development aims to democratize access to advanced AI search technology. The business model operates on a freemium basis, offering tiered pricing for API usage and premium features, with an estimated annual revenue of around $17.5 million. Clients range from e-commerce and media companies to banks and consulting firms, using the tools for everything from product search and recommendations to internal data analysis.

Jina AI successfully raised a total of $39 million over two funding rounds. This included a Series A round of $30 million in November 2021, led by Canaan Partners with participation from investors like GGV Capital and SAP.iO. On October 9, 2025, Jina AI was acquired by Elastic (NYSE: ESTC), the Search AI Company. Following the acquisition, Han Xiao became the VP of AI at Elastic. The integration aims to combine Jina AI's advanced models with Elastic's platform to enhance capabilities in vector search, RAG, and context engineering.
