Pick Grasshopper if…
The OCC-chartered US national bank for startups — the structural distinction from Mercury / Brex / Bluevine / Rho is that Grasshopper IS the bank. Direct FDIC cover at the chartered-bank level, multi-bank Cash Sweep extending to $25M. Free business checking with API access. The structural fit for US-incorporated startups wanting a real bank relationship rather than a partner-bank fintech.
