## What the models said for it

- "Brex is best if you run a mid-market company and want a corporate card plus treasury and vault services in one platform." (Claude Haiku 4.5, Business banking)
- "Brex (Best for High-Velocity Startups) ... high credit lines, virtual cards for security, and excellent employee management" (Qwen 3.7 Flash, Corporate cards)
- "Brex offers both banking and corporate card services designed for venture-backed startups and mid-market companies" (Claude Haiku 4.5, Business banking)
- "Ramp, Brex, and Zoho Expense, which are often cited as friendlier alternatives — especially for small teams" (DeepSeek V4 Flash, Expense management)

## And against it

- "Brex abruptly decided to stop servicing traditional small businesses, giving tens of thousands ... just 60 days to move their funds" (Gemini 3.5 Flash, Business banking)
- "it is not recommended for limited-budget companies unless you are venture-backed" (Gemini 3.5 Flash, Corporate cards)
- "Brex requires businesses to hold at least $400,000 in monthly revenue for mid-market underwriting. This shuts out many bootstrapped or lower-revenue businesses." (DeepSeek V4 Flash, Corporate cards)
- "the platform may see shifts in product direction and pricing, which is something to keep in mind if you are looking for long-term platform stability" (Gemini 3.5 Flash, Corporate cards)
