Vectara

Vectara provides an API-first platform for enterprises building AI agents and assistants grounded in their own data. Developers can combine retrieval across text, documents, and images with generation, conversational context, and tool use. The platform brings retrieval, orchestration, and observability together, with audit trails, access controls, and factual-consistency checks to help teams build and govern applications without assembling each part themselves.

Founded in 2020 by Amr Awadallah, Amin Ahmad, and Tallat Shafaat, Vectara is now led by co-founder and CEO Tallat Shafaat. Its research contributions include the Hughes Hallucination Evaluation Model (HHEM), released openly in 2023 to assess whether generated text is supported by its input. This measures consistency with supplied evidence, rather than universal truth. An improved version powers Vectara’s Factual Consistency Score; the company reported more than 100,000 downloads of HHEM by April 2024.

Vectara supports SaaS, VPC, on-premises, and air-gapped deployment, giving organizations choices over where their data and agents operate. Enterprise applications extend beyond internal knowledge search into failure analysis, contract lifecycle management, and manufacturing workflows. In 2026, the company named Sandisk and Altera as new customers and described Broadcom’s use in customer experience and silicon engineering.
