Movement

This is the first edition on this tier, so no move can be computed for ClientSuccess yet. The next is due October 1, 2026. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

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

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Start with ChurnZero or ClientSuccess demos—they're the most commonly recommended for your segment” Qwen 3.7 Flash · Customer success · direct prompt · first choice
“If you want a simple, clean workspace and need to be up and running by next month: Go with ClientSuccess or Custify.” Gemini 3.5 Flash · Customer success · comparative prompt · alternative
“Choose Custify or ClientSuccess if: ... startup needing affordable, flexible solutions” Kimi K2 · Customer success · comparative prompt · alternative
“Choose ClientSuccess if you want a lighter, simpler mid-market CS platform” Perplexity Sonar · Customer success · paraphrase prompt · alternative

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.

“What to Avoid on a Budget ... generally not where you should start” DeepSeek V4 Flash · Customer success · budget prompt · hard negative
“Avoid: Gainsight, ClientSuccess, Salesforce Service Cloud” GLM 4.7 FlashX · Customer success · negative prompt · hard negative

What carried it into the answer

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

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 17 of the 95 answers that named ClientSuccess and are not a share of its labels.

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 ClientSuccess'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 ClientSuccess, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at clientsuccess.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
