Which one is a better deal?
Depends on what you need. Mercury: Mercury sits mid-to-premium in the startup banking space — free tier keeps them competitive with Brex and Ramp on customer acquisition, but the $299 Pro tier signals they're chasing more mature, funded companies willing to pay for treasury and yield features rather than staying purely ad-supported-free like some fintech competitors. Brex: Brex undercuts on sticker price compared to Ramp and Airbase, especially with a genuinely free tier, but the $12/seat Premium plan signals they're not trying to win on being the budget option forever. This is a land-grab strategy — get startups in free, then monetize as they scale and become harder to rip out.
