Very well suited for founders who are building companies in the US but are not US citizens. Works like a charm for start-ups who are looking for a cutting-edge product and not an outdated bank! Small-medium teams. Not well suited for those who are used to traditional banking and prefer in-person interaction or over the phone.
With a web and app product, it is easy to implement across a large company. The system provides dropdowns (for the various types of expenses) that seem to be customer customizable. This probably provides a seamless interface to a company's internal accounting system. I think for companies that want to provide a really good and easy user experience, and considers that in their selection process, may not be good candidates for implementing this software.
Rewards - The rewards were the main reason for us switching. Our previous card provider did not have a good rewards program.
User Interface and experience - When a charge is recorded on the Brex card, users immediately receive a text notification asking them to send a picture of their receipt. Brex automatically attaches the receipts to the charge which has saved our users a significant amount of time.
The way our firm uses ExensAble has not led to any problems or complaints. We set it up years ago and it's been running smoothly ever since. If others who use the system have had any complaints I am not aware of them.
Divvy allows you to get hyper focused in on how much individuals are allowed to spend. Honestly it is comparable to Brex, but is more well suited for micromanaging organizational spend. Brex is good because I am able to give my employees limits that match our budgets and I don't care about micromanaging their spend.
