The startup has raised $87.8 million across multiple funding rounds, including a $50 million Series B in 2025, and is used by major companies including X/xAI's Grok platform. The company's vector database enables developers to build advanced AI applications for semantic search, recommendations, and retrieval augmented generation (RAG), with notable customers including GitBook, VoiceFlow, and Dust.
