MongoDB (NASDAQ:MDB) shares jumped 12.2% in Thursday trading, buoyed by a rally across software names that followed robust results from Datadog (NASDAQ:DDOG). The sector-wide lift came after Datadog reported a stronger-than-expected quarter and raised its guidance, a report that sent Datadog shares up about 30% in premarket trading and helped sentiment across technology stocks.
Separately, at its MongoDB local London 2026 conference on Wednesday, MongoDB rolled out several AI-focused capabilities and a new database release. The company introduced Automated Voyage AI Embeddings within MongoDB Vector Search, which is available in public preview and automatically generates embeddings as data is written or updated.
MongoDB also launched version 8.3 of its database software. According to the company, MongoDB 8.3 offers material performance gains relative to MongoDB 8.0: up to 45% more reads, 35% more writes, 15% more ACID transactions, and 30% more complex operations. In addition, the LangGraph.js Long-Term Memory Store integration is now generally available, providing JavaScript and TypeScript developers with persistent agent memory functionality powered by MongoDB Atlas.
The company said its Voyage AI embedding models rank first on the Retrieval Embedding Benchmark, a ranking it attributed to its internal testing. MongoDB framed these updates as part of an effort to consolidate database, search, memory, and embedding capabilities to simplify deployment of AI agents on a single platform.
"The hardest part of running agents in production isn’t the model. It’s the data layer underneath it," said CJ Desai, President and Chief Executive Officer of MongoDB.
On the networking front, MongoDB announced that cross-region connectivity for AWS PrivateLink is now generally available, enabling database traffic between MongoDB Atlas clusters in different AWS regions to remain on the AWS private network.
The share-price movement appears to reflect a mix of sector momentum led by Datadog’s earnings and investor interest in MongoDB’s new product capabilities and stated performance improvements.
