Braintrust will expand engineering and sales as developers need to inspect longer, more complex AI workflows.
An AI agent can make many model and tool calls before completing a task. Braintrust gives teams a way to examine those interactions and evaluate the results. It has built a database to handle the volume and complexity of these traces.
Customers named in the announcement include Notion, Replit, Cloudflare, Ramp and Dropbox. The new capital will support engineering and go-to-market hiring, additional offices and product development.
MatX designs processors specifically for large language models, combining specialized computation and memory architecture for training and inference.
Temporal provides open-source software and a managed cloud service that preserve workflow state, so applications can recover from failures and finish long-running work.
Bedrock Robotics develops autonomy systems that retrofit construction machines, including excavators, bulldozers and loaders, to perform work with less direct operator involvement.
