By framing
What the models said for it
Verbatim evidence the judge attached to positive labels.
“1. Sierra (Best Overall for Mid-Market B2B)” Claude Haiku 4.5 · AI voice agents · paraphrase prompt · first choice
“Choose Sierra if you are a large enterprise brand looking for a premium, omnichannel solution” GLM 4.7 FlashX · AI voice agents · comparative prompt · alternative
“Sierra AI is best for maximum brand governance and tone control” Claude Haiku 4.5 · AI voice agents · comparative 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.
“Why avoid: Not suitable for mid-market buyers or those with under 100 concurrent calls.” Mistral Small · AI voice agents · negative prompt · hard negative
“Sierra - if you have under 100 concurrent calls, no dedicated operations team, or if your budget is under $50,000 annually.” Llama 4 Maverick · AI voice agents · negative prompt · soft negative
“Not recommended for mid-sized B2B companies unless you have a massive support volume and a large budget.” DeepSeek V4 Flash · AI voice agents · paraphrase prompt · soft negative
“cautious if you want a self-serve platform, transparent pricing, or a simple setup” Perplexity Sonar · AI voice agents · negative prompt · soft negative

How it is countedHide how it is counted
Every page sierra.ai 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.

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 Sierra'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 Sierra, 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 Sierra by email, built from the raw record of the edition. It shows:
- where Sierra 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 Sierra, 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.
