What we observed in this categoryauto-generated
Vonage leads the CPaaS platforms category with a visibility score of 50.0%, more than double the 25.0% shared by Twilio, Sinch, Telnyx, and Bandwidth. The category average visibility sits at just 8.8%, making Vonage's position a significant outlier. This gap matters because AI Mode is consistently surfacing Vonage in responses at a rate that no other single brand approaches, giving it a structural naming advantage that compounds over repeated queries.
The most striking divergence in this data is between Infobip and Sinch. Infobip holds only 12.5% visibility but leads all brands on citation rate at 37.5%, suggesting AI Mode trusts its content as a reference source even when not naming it prominently. Sinch, Telnyx, and Bandwidth each sit at 25.0% visibility but carry zero citation rate, meaning they are named in responses but their own domains are not being pulled as sources to back those mentions.
Every brand in this dataset lists Google AI Mode as its top engine, confirming the audit is entirely concentrated on a single engine. The top cited third-party sources anchoring AI responses include g2.com, gartner.com, and cloudcommunications.com, alongside more niche properties like twixor.ai and cxfoundation.com. This suggests Google AI Mode is drawing heavily from review aggregators and analyst sites rather than brand-owned content when constructing CPaaS category responses.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on cpaas platforms, these are the domains Google AI Mode cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer.
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence — different from being named.
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps.
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically.
