Vectara
Vectara is a Palo Alto-based enterprise AI company building a trusted, end-to-end platform for retrieval-augmented generation (RAG) and AI agents. Founded in 2022 by former Google AI researchers, it lets companies embed grounded, citation-backed GenAI - conversational assistants, semantic search, and agents - into their products while actively detecting and correcting hallucinations at runtime. Its stack includes the Boomerang embedding model, the RAG-tuned Mockingbird LLM, the open-source Hughes Hallucination Evaluation Model (HHEM), and a Guardian Agent layer, positioning Vectara as a leader in factual, secure, compliance-ready enterprise AI.
Jeremy Suh
Jeremy Suh is a San Francisco-based software engineer and co-founder who built Browser Buddy - an AI-powered recommendation engine for high-quality internet writing - through Y Combinator's Winter 2024 batch. Exa, the AI search infrastructure company redefining how developers access web data for LLMs, acquired Browser Buddy in its first-ever acquisition, bringing Jeremy and co-founder Arnav Wadehra onto the team. At Exa, he works on new approaches to retrieval and web organization at a company now valued at $2.2 billion following a $250 million Series C led by Andreessen Horowitz in 2026.
Exa
Exa is an applied AI lab building a search engine for AIs. Their neural search API lets developers and AI agents retrieve high-quality, factual content from the web using natural-language queries, powering RAG, research agents, and enterprise knowledge workflows.
Will Bryk
Will Bryk is the co-founder and CEO of Exa, a neural search engine built for the AI era. A Harvard CS and physics graduate who interned at SpaceX and engineered AI products at Cresta, Bryk left to answer a question that gnawed at him: what if Google was already obsolete? Exa reimagines search using transformer-based link prediction - what Bryk calls 'neural PageRank on steroids' - to help AI agents find exactly the right information rather than keyword-stuffed SEO noise. The company raised $85M in a Benchmark-led Series B at a $700M valuation in September 2025, with Nvidia and Lightspeed also backing the bet that AI systems will soon generate more search queries than humans.
