1. Tell me what the rewards are. Right now I get credit card reward points worth ~1.5% of my monthly spending; I'm not going to switch cards based on "we have fantastic rewards, trust us!"
2. Find a way to integrate with Stripe! They've already done all the AML/KYC stuff, and they also have plenty of information about my revenue. For that matter, why have money bounce via a bank account -- find a way for me to have the money I receive via Stripe pay off the Brex card first.
3. Seconding the request to support people outside of the USA. My company does its banking via a US bank account but both I and my company are based in Canada.
