I just received my Mercury.co debit card in the mail, and now I'm planning to move all my money from SVB into Mercury and close my SVB account. I already use Brex for corporate credit cards, and they've been awesome. It looks like I will need to "request early access" for Brex Cash (and I probably don't meet their requirements since I'm not VC funded), so I'm not going to wait around for that.

However, Stripe is the very core of my business. They already offers corporate credit cards, but I've never thought about switching or adding new cards, because I'm very happy with Brex. I use Brex virtual cards for everything now, and I recently received a physical card that I can use for flights and hotels.

However, if Stripe ever offers a bank account in the future, then I'll immediately close my Brex and Mercury accounts and just migrate everything into Stripe. Nothing would beat a single login where I have my bank account, debit cards, credit cards, and all of my customer payments. Also Stripe is much bigger and I have much more trust in their security and engineering teams.
