B2B intent data providers

Asked as “B2B intent data provider”, and as “B2B buyer intent data vendor”, on behalf of a mid-market B2B company. 52 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.
Standing
Contested
G2 Buyer Intent and Apollo.io tie at 25%, but they part on sentiment: 8% negative against 30%. The established intent vendors are the criticized ones.

By buyer segment

The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

02What they warned about

Three of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, Gemini 3.5 Flash, Perplexity Sonar, Grok 4.1 Fast, Mistral Small, Llama 4 Maverick, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.

03What they cite

Citations exist only for the models that return a source list: four of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

22 of 72 answers in this category came back with a source list, from 4 of 12 models: citations where the model returns them, or the search results it consulted. 6 of those lists are Google grounding redirects that name no site and are left out of the counts. 207 links across 77 sites, every framing counted. Ranked by the number of answers carrying the site or page. The other 8 models searched through a gateway that returned no source list on this edition.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best B2B intent data provider for a mid-market B2B company?”Paraphrase“Which B2B buyer intent data vendor would you recommend to a mid-sized B2B company?”Comparative“What are the top B2B intent data providers and how do they differ?”Budget-constrained“What is the best B2B intent data provider for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating a B2B intent data provider.
