Founded 2020|Palo Alto, CA, USA|33 employees

What is Vectara?

Vectara is a serverless RAG-as-a-Service platform that provides a complete AI Agent solution including document processing engine, intelligent chunking, state-of-the-art embedding model, and proprietary internal vector database with high-quality retrieval engine. Founded by former Google executives, Vectara solves critical enterprise adoption challenges by reducing hallucination, providing explainability and provenance, enforcing access control, enabling real-time knowledge updatability, and mitigating intellectual property and bias concerns from large language models. The cloud-based GenAI platform runs on AWS or GCP infrastructure in Vectara's SaaS environment or can be deployed in your own VPC or on-premise installation. Vectara supports 100+ languages without extra setup, combines semantic understanding with keyword search for better precision, and automatically scales to traffic spikes without manual intervention, all while maintaining SOC 2, HIPAA, and GDPR compliance.
