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.
Latent Knowledge
Latent Knowledge is a New York-based AI company building LitView, a semantic search and literature-visualization tool that helps R&D teams and academic researchers discover, cluster, and map scientific literature beyond simple keyword matching. Founded in 2019 by James Reilly, the company uses applied natural language processing to surface hidden links between technical articles and speed up the research process across public and private data sources.
Orama
Orama is an open-source search company building an 'answer engine' for developers - a lightweight, high-performance stack that bundles full-text, vector, and hybrid search with automatic embedding generation and built-in LLMs. Started as the open-source project Lyra and incorporated as OramaSearch Inc. in 2023 by Issac Roth and Michele Riva, its core library ships in under 2KB and runs in the browser, on servers, or at the edge. Orama powers site search and AI answers for developer platforms including nodejs.org, tanstack.com, and solidjs.org, and its OramaCore runtime packages a search engine, vector database, and LLM interface into one deployable unit.
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.
TwelveLabs
TwelveLabs is a San Francisco-based AI company building video-native multimodal foundation models that give machines the ability to see, hear, and understand video the way humans do. Its flagship models - Marengo for embedding and retrieval and Pegasus for video-to-text generation - power enterprise applications in media, government, sports, and security, enabling precise semantic search, summarization, and insight extraction from video at scale. With 30,000+ developers on its platform and backing from NVIDIA, Databricks, Snowflake, and In-Q-Tel, TwelveLabs is becoming the standard infrastructure layer for video intelligence.
Thanh Tran
Thanh Tran is Co-CEO of A5 Labs, a Foster City-based AI company building game integrity infrastructure for competitive online gaming. With a PhD in Computer Science from Karlsruhe Institute of Technology and a background scaling Upwork's data science team through its IPO, he now leads a 180-person team applying deep reinforcement learning, blockchain reputation systems, and real-time behavioral analytics to eliminate bots, collusion, and cheating from online poker and beyond.
Daniel Svonava
Daniel Svonava is the Co-Founder and CEO of Superlinked, an ML infrastructure company building self-hosted inference infrastructure for vector search and document processing. A Slovak-born engineer and entrepreneur based in San Francisco, he spent six years as an ML Tech Lead at YouTube building ad performance systems powering over $10B in annual ad revenue before co-founding Superlinked in 2021. Superlinked raised a $9.5M seed round led by Index Ventures in March 2024, and the company is on a mission to make vector-based retrieval accessible and production-ready for enterprises.
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.
Vicki Boykis
Vicki Boykis is a founding ML engineer and one of the most respected voices in applied machine learning. Known for making complex systems legible through rigorous writing and dry wit, she runs the Normcore Tech newsletter, authored a widely-cited deep dive on embeddings, built Viberary (a semantic book recommendation engine), and created Normconf - an unconventional data conference celebrating the unglamorous realities of ML work. She brings an economist's skepticism and a software engineer's discipline to a field that often confuses hype for progress.
