Webinar and virtual event platforms

Asked as “webinar and virtual event platform”, and as “platform for hosting webinars and virtual events”, on behalf of a mid-market B2B company. 44 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.
Standing
Contested
41% of first choices at a 6% negative rate, against a field where the incumbents are named mostly to be warned against: Zoom, GoTo, Teams and ON24 all clear 29% negative.

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.

01The standing

02What they warned about

Three of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Perplexity Sonar, Grok 4.1 Fast, Mistral Small, Llama 4 Maverick, Qwen 3.7 Flash, Kimi K2 and GLM 4.7 FlashX 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

20 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. 5 of those lists are Google grounding redirects that name no site and are left out of the counts. 201 links across 95 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 webinar and virtual event platform for a mid-market B2B company?”Paraphrase“Which platform for hosting webinars and virtual events would you recommend to a mid-sized B2B company?”Comparative“What are the top webinar and virtual event platforms and how do they differ?”Budget-constrained“What is the best webinar and virtual event platform for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating a webinar and virtual event platform. What should we look at?”Negative“Which webinar and virtual event platforms should I avoid or be cautious about?”
