Brex is gone. Mercury's window is wide open.

Capital One acquired Brex for $5.15B in January 2026. Startup founders don't want to bank with legacy institutions. Mercury is the obvious beneficiary, but only if it moves fast.

QuicksilverOS identifies and captures that migration, tracks competitive dynamics in real-time, and ensures no opportunity slips through.
