Database and AI retrieval platform

MongoDB

MongoDB builds a document database and multicloud data platform for developers creating operational and AI applications. MongoDB Atlas combines operational data, search, real-time analytics and AI retrieval. Its automated embeddings, powered by Voyage AI, embed documents as they are written and update embeddings when documents change, helping applications retrieve current context. The Atlas Embedding and Reranking API also makes these models available to applications running outside MongoDB.

Dwight Merriman, Eliot Horowitz and Kevin Ryan founded the company as 10gen in 2007; the database launched in 2009. Chirantan “CJ” Desai is its current President and CEO. MongoDB’s flexible document model is complemented by distributed, multi-document ACID transactions, supported since 2019. Its engineering research uses TLA+ specifications to check transaction isolation and interactions with the WiredTiger storage engine, and measures how much concurrency a transaction protocol permits.

MongoDB serves organizations across industries and more than 100 countries. The company reported over 67,700 customers as of April 30, 2026, including over 66,400 Atlas customers; these counts exclude free users and group affiliated entities together. Atlas supports consumption with minimal commitment, allowing customers to add workloads as their needs grow.

  4. The State of AI-Powered Search and Retrieval

    Frank Liu of MongoDB and the former Voyage AI team explains how semantic, embedding-based search moves beyond lexical retrieval and improves grounding in retrieval-augmented generation.

Messages from the stage

Retrieval mechanics and quality

Ben Flast explains document storage, HNSW indexes, and vector-search tuning. Frank Liu adds embedding quality, reranking, and application-specific evaluation, connecting retrieval infrastructure to the relevance of returned context.

Memory and perception in agents

Richmond Alake distinguishes conversational, entity, working, short-term, and long-term memory. Apoorva Joshi’s multimodal workshop connects text-image inputs and application-executed functions with Voyage AI embeddings and MongoDB vector storage.

Requirements before implementation

Using a hypothetical claims-review application, Apoorva Joshi ties architecture choices to business goals, human-review constraints, guardrails, and evaluation. Production monitoring includes human override rates and review time.

Affiliations reflect each recorded session, not necessarily current employment. The multimodal workshop recording ends as participants begin the hands-on lab.
