Brex

Brex provides a unified platform to manage your company's entire financial life cycle in one place. You can issue physical and virtual corporate cards to your team, set granular spending limits, and automate expense reports before they even happen. The platform integrates your business account, credit cards, and bill pay into a single dashboard, giving you real-time visibility into every dollar spent across your organization.

Designed primarily for venture-backed startups and mid-market enterprises, Brex helps you scale without the manual overhead of traditional banking. You can manage global entities with multi-currency support and sync all transaction data directly to your accounting software. By eliminating the need for personal guarantees on corporate cards, it allows you to access higher credit limits based on your company's cash balance rather than your personal credit score.
