#2 avg. position
+1 ahead of HubSpot

Klaviyo and HubSpot are inseparable at the top, both appearing in every single answer with near-identical position-weighted scores.

Klaviyo edges HubSpot by a single point (89 vs 88) and both land in 100% of the 12 answers across all models, averaging position 2 each — a statistical dead heat that makes this question genuinely unresolved. The answers themselves explain why: Klaviyo gets cited for purpose-built ecommerce automation and native Shopify sync, while HubSpot is credited for bridging marketing, sales, and support in one platform, so the two win on different buyer profiles rather than the same one. Below them, Omnisend appears in 58% of answers but ChatGPT accounts for all 4 of its mentions while Gemini picks it up only once, making that a model-specific lean rather than a consensus view. Drip and Zoho CRM both sit at 50% presence but trail badly on position weight, confirming they function as supporting depth rather than real contenders for the top recommendation.

AI-generated analysis of the September 2026 measurements.

The full field

Every brand recommended for this question, from 12 answers across ChatGPT, Perplexity, and Gemini.

# Brand Slot score Appears in Avg. position
1 Klaviyo 89 100% #2
2 HubSpot 88 100% #2

7 Salesforce 23 42% #6
8 Nutshell 22 25% #3

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.

Other surfaces

Model memory (same assistants, no web access) Klaviyo (same winner)
Google AI Mode (the real surface, scraped) Klaviyo then HubSpot, Omnisend
Google AI Overviews (the real surface, scraped) Klaviyo then HubSpot, Pipe Drive

The main measurement above is the assistants' real answers with live web access. These rows show the same question on other surfaces: the models' bare memory, and Google's own AI search experiences.

How this was measured

ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:
