Brex has run into a bit of an odd situation in recent years—while focusing on growth, they apparently took on too many small-mid size businesses, which led to them axing accounts of many of their customers out of nowhere. They are now only allowing venture-backed startups onto their platform, or mid-size businesses doing at-least $400k/mo in revenue ($4.8m/yr).

We actually had a Brex account for many years when first evaluating it (checking in on how it evolved over the years), and recently, we were actually one of the many that were pulled into the axing account mess (luckily we ultimately decided on Divvy after initial evaluation of Brex, and have been happily using Divvy for 5+ years now). That said, when trying to log back into my account to add some screenshots to this post, I was met with a redirection loop and the following message from support upon reaching out:

While they have a "banking" component, it's more of just a simple checking account, and their banking features are not as robust as that of a full-fledged business-focused bank like Mercury.

All-in-all, they seem to be relying quite heavily on their YC network, getting most YC companies to use them by offering as many perks to them as possible. When actually comparing Brex against the competitors though when it comes to automatic reconciling of your expenses in your accounting software, and just overall UI/UX, there's a lot to be desired—Divvy and Ramp are far superior in many of those areas.
