The Brex Assistant

The Brex Assistant is an AI agent that acts as an executive assistant for every employee handling the expense, spend, and travel busywork they'd otherwise do by hand, and meeting them where they already are, in chat and over SMS. No app to open, no form to fill; the agent understands what you need and takes real actions on your behalf, in a conversation.

The vision is broad: nearly anything an employee or manager does around their spend, the Assistant can help with. Swipe your card and it reaches out to document the charge moving it to the right spend limit, drafting a memo from your calendar, pulling in attendees, checking your policy, and requesting the receipt. Beyond that, it files reimbursements, answers spend and policy questions, helps with Brex travel (from booking to sorting out issues that come up mid-trip), and chases the expense follow-ups that normally pile up. It's one of the most agentic products at Brex: the experience leads with conversation rather than screens and forms, so the agent has to genuinely understand what you need and take the right actions not just point you to where you could do it yourself.

The card is at the center of how Brex works, so an assistant that strips the friction out of every swipe is one of the company's highest-leverage bets. For most employees, the card plus this agent can become the only part of Brex they ever touch.

It's an early-stage product with real momentum: no one has a finished playbook for building reliable, action-taking agents in the financial space the right evals, the right feedback loops, the right way to keep an agent trustworthy as models and tooling shift underneath you. You'll invent much of that, with the ownership and pace of a startup and the backing of an established company behind you.
