Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 10 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“I would generally recommend Brex if you want an all-in-one platform for banking, cards, treasury, and spend management” Perplexity Sonar · Business banking · paraphrase prompt · first choice

“For most mid-market B2B companies, Airbase and Brex are the top choices” Mistral Small · Corporate cards · direct prompt · first choice

“Ramp, Brex, and Divvy are frequently mentioned by small businesses.” MiniMax M2.5 · Corporate cards · budget prompt · first choice

“Choose Ramp/Brex if you want modern automation and card-led spend control.” GPT-5.4 mini · Corporate cards · comparative prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Avoid: - Brex (if you're small, international, or need stable limits — the Trustpilot reviews are brutal)” DeepSeek V4 Flash · Corporate cards · negative prompt · hard negative

“Brex (Avoid if you are a bootstrapped or traditional small business)” Gemini 3.5 Flash · Expense management · negative prompt · hard negative

“Brex (Avoid if you are a traditional, non-VC-backed small business)” Gemini 3.5 Flash · Spend management platfor · negative prompt · hard negative

“Brex has a history of pivoting away from small businesses... introduces long-term uncertainty regarding how underwriting requirements and platform fees will evolve.” Gemini 3.5 Flash · Corporate cards · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Brex. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 640 of the 672 answers that named Brex and are not a share of its labels.

How it is countedHide how it is counted

Every page brex.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read September 29, 2026.

Names read as Brex

What the judge wrote, as written, with how often. The vendor table decides that these count as Brex; a claim can dispute any of them.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Brex's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Brex, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Brex by email, built from the raw record of the edition. It shows:

where Brex is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name Brex, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.

Badges

Wins only: a badge exists where Brex is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.

ShowHide

Brex is among the products AI models recommend first in Corporate cards this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
