Movement

This is the first edition on this tier, so no move can be computed for Five9 yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Five9 across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“my default recommendation would be Five9 or Genesys Cloud, with Five9 as the best "safe" first pick” GPT-5.4 mini · Contact center · paraphrase prompt · first choice

“Five9 is the top choice due to its comprehensive omnichannel capabilities and workforce management” Mistral Small · Contact center · direct prompt · first choice

“Genesys Cloud CX or Five9 as the primary contenders (proven mid-market to enterprise scale)” Kimi K2 · Contact center · scale prompt · first choice

“I'd recommend Five9 as a strong starting point among cloud contact center (CCaaS) options.” Grok 4.20 · Contact center · paraphrase 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.

“has accumulated a significant volume of negative feedback in recent years regarding its transition to fully managed services” Qwen 3.7 Flash · Contact center · negative prompt · hard negative

“Call issues: Frequent call drops and technical disruptions” MiniMax M2.5 · Contact center · negative prompt · hard negative

“Five9 is a reputable CCaaS, but if you prioritize a modern UI, tighter cost control... its cons are worth investigating before committing.” GLM 4.7 FlashX · Contact center · negative prompt · soft negative

“Higher cost makes it less accessible for smaller businesses, complexity in initial setup and configuration exists” Claude Haiku 4.5 · Contact center · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Five9. 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 199 of the 213 answers that named Five9 and are not a share of its labels.

As the event pages on five9.com state them, read September 28, 2026.

How it is countedHide how it is counted

Every page five9.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 Five9

What the judge wrote, as written, with how often. The vendor table decides that these count as Five9; 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 Five9'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 Five9, 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 Five9 by email, built from the raw record of the edition. It shows:

where Five9 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 Five9, 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 Five9 is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.

AI models recommend Five9 first in Contact center platforms 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.
