There is a statistic doing the rounds in B2B decks right now: “51% of B2B software buyers begin vendor research in an AI chatbot, up from 29% in April 2025.” It is being quoted as if half of all software buying journeys now open in ChatGPT instead of Google. We traced the figure to its owner, and that is not quite what the owner’s page says. This post covers what G2 actually measured, where the wording drifted (including in G2’s own press headline), and what changes for a B2B sales and marketing team when discovery happens inside a chatbot before you ever see the buyer.
At a glance: G2’s Answer Economy report (March 2026 survey of 1,076 B2B decision makers) found that 51% of B2B software buyers start their research with an AI chatbot more often than Google — a relative-frequency comparison, not “half of all journeys begin in a chatbot”. The comparator is routinely dropped in circulation. The trend is still real and steep: the same measure was 29% in G2’s April 2025 survey. The practical consequence: inbound buyers increasingly arrive pre-shortlisted by a machine you never pitched — so visibility, response speed and the first conversation all have to change.
What the owner’s page actually says
The circulating claim usually cites “G2” loosely; some write-ups point at G2’s Buyer Behavior Report. The figure does not live there. It comes from a different G2 publication, The Answer Economy: G2’s 2026 AI Search Insight Report. The exact wording:
“51% of B2B software buyers start their research with an AI chatbot more often than Google.”
The methodology, from the same page: G2 fielded an online survey among 1,076 B2B decision makers responsible for, or influencing, purchase decisions, conducted in March 2026 across North America, EMEA and APAC.
The 29% baseline checks out too, with the same comparator. The 2025 report itself sits behind a form, so we verified the wording in G2’s own release announcing it, which describes a survey of 1,169 B2B decision makers in April 2025 and reports “29% noting they start research via LLMs more often than Google”. G2’s Answer Economy article confirms the figure: “When we published our 2025 Buyer Behavior Report, that number was just 29%.”
Now the drift. G2’s own press headline reads “New G2 Research: Half of B2B Software Buyers Now Start Their Research With AI Chatbots” — the comparator is gone (the release body restores it). By the time the stat reaches LinkedIn, it has become “half of buyers begin research in a chatbot”: a different claim.
| Version | Wording | What it implies |
|---|---|---|
| Owner’s report (primary) | “51% of B2B software buyers start their research with an AI chatbot more often than Google“ | For a slim majority of buyers, a chatbot has overtaken Google as their more frequent starting point |
| G2’s own PR headline | “New G2 Research: Half of B2B Software Buyers Now Start Their Research With AI Chatbots” | Ambiguous — reads as if half of journeys begin in a chatbot |
| Circulating version | “51% of buyers begin vendor research in an AI chatbot” | Half of all research journeys open in a chatbot — not what was measured |
Why be pedantic? Because the honest version changes how you should react. “Half of journeys start in ChatGPT” would argue for abandoning search overnight. The measured claim says something more precise: the chatbot has crossed from novelty to default starting point for a majority of buyers, while Google stays in the mix. G2’s article adds that 71% of buyers rely on AI chatbots at some point in their research — the chatbot is not replacing the journey; it is embedding itself in every stage of it.
The part that should actually worry you
The headline number is the least operational finding in the report. These two, from G2’s own summary of the research, matter more for a revenue team:
- “69% of buyers chose a different vendor than initially planned, simply because it was part of the chatbot’s recommendation.” The chatbot is not a passive research tool — it is actively rerouting deals.
- “One in three purchased from a vendor they’d never previously heard of.” Brand familiarity, the moat B2B marketing spends most of its budget building, can be bypassed by a model that surfaces an unknown vendor with the right evidence trail.
- “85% of buyers think more highly of a vendor when AI includes them in an answer.” An AI mention now functions as third-party endorsement, whether or not the model deserves that trust.
Put together: a growing share of your pipeline is being shaped in a conversation you cannot see, by a system you cannot brief. That is the change worth planning for — not the precise percentage on the poster.
Classic funnel vs chatbot-first discovery
Neither column is universally true — most buyers blend both — but the right-hand column is the growing mode.
| Stage | Classic search-led funnel | Chatbot-first discovery |
|---|---|---|
| Problem framing | Buyer googles symptoms, reads a dozen blog posts, self-educates over weeks | Buyer describes the problem conversationally; the model frames the category and names the solution class in minutes |
| Longlist building | Ten blue links, category roundups, analyst grids; vendors compete for rank | The model synthesises a shortlist directly from reviews, docs and comparison content; vendors compete for citation |
| Comparison | Buyer opens vendor sites, downloads gated PDFs, builds their own spreadsheet | Buyer asks the chatbot to build the comparison table; follow-up questions replace tab-hopping |
| What you can observe | Search impressions, rankings, page visits, content downloads — a rich intent trail | Almost nothing until the buyer surfaces; the research trail lives in a chat history you will never see |
| First vendor contact | Mid-funnel: buyer is still forming criteria and open to education | Late-funnel: buyer arrives with a machine-built shortlist and provisional conclusions — sometimes wrong ones |
| Volume vs intent | High traffic, mixed intent, long nurture cycles | Fewer, later, hotter arrivals; each conversation carries more of the deal |
| What wins | Rankings, domain authority, paid coverage | Being quotable, consistent across sources, well-reviewed, and easy for a model to verify |
What a B2B sales and marketing team should change
1. Treat AI visibility as a channel, not a curiosity
You cannot buy placement in a chatbot answer, but you can influence what the model reads: consistent entity facts everywhere your brand appears, quotable pages with direct answers, structured comparison content, and honest third-party corroboration — review profiles included, since review platforms are exactly the kind of source these models synthesise. We published a full playbook in Zero-Click AI Answers: Being the Brand AI Recommends, so we will not repeat it here.
2. Re-weight your measurement
Chatbot-referred traffic is still a small fraction of web visits, but the visitors it sends tend to be disproportionately valuable because the model has already done the qualifying — we examined the conversion evidence in Do AI-Search Visitors Convert Better? The implication: tag AI referrers separately, sample your visibility with scheduled buyer-style prompts, and stop judging content solely on sessions — a page that gets cited but not clicked is doing revenue work your analytics undercount.
3. Redesign the first sales conversation
When 69% of buyers report changing vendor plans on a chatbot’s say-so, the first call is no longer a blank-slate discovery session. The buyer arrives with a machine-assembled view of your category, your competitors, and probably you — some of it stale or plain wrong. Train reps to surface it early (“what did the tools you used tell you?”), then validate or correct with evidence rather than pitching from slide one. Correcting a chatbot’s confident error about your product is now a core sales skill.
4. Compress your response time to match compressed research
A buyer who spent three weeks reading blog posts could tolerate a next-day follow-up. A buyer who framed the problem, built a shortlist and drafted questions inside one chatbot session is moving at a different tempo — and one in three of them, per G2, purchased from a vendor they had never previously heard of. The window between “surfaced on your site” and “committed elsewhere” is shrinking. This is where autonomous outreach earns its keep: Zian’s AI sales agents are built to engage an inbound lead within moments across phone, SMS, email and WhatsApp, hold the conversation in 30+ languages, and book the meeting while the research session is still warm — rather than joining a queue for tomorrow’s SDR shift.
5. Publish what the model needs to recommend you
Chatbot-first buyers reward vendors whose facts are checkable. Clear feature scoping, honest comparison pages naming real alternatives, current documentation, and specific sourced claims all give a model something to cite. Gated PDFs, superlative-heavy homepages and unverifiable stats give it nothing — or a reason to cite your competitor’s clearer page when a buyer asks about you.
6. Audit the stats in your own deck
The meta-lesson: the most-quoted number in this space drifted from its own source — starting with the owner’s press headline. If your team cites “half of buyers start in a chatbot”, correct it to what G2 measured. Strategy built on a misread stat overcorrects, and the honest version already justifies action.
FAQ
Do half of B2B software buyers really start vendor research in an AI chatbot?
Not exactly as commonly quoted. G2’s 2026 AI Search Insight Report (March 2026 survey, 1,076 B2B decision makers) found that 51% of B2B software buyers start their research with an AI chatbot more often than Google — a comparison of starting-point frequency, not a claim that half of all research journeys begin in a chatbot. The distinction is routinely lost in circulation.
Where does the “up from 29% in April 2025” part come from?
From G2’s 2025 Buyer Behavior Report, which surveyed 1,169 B2B decision makers in April 2025 and found 29% started research via LLMs more often than Google. Same comparator, same owner, so the 29%-to-51% trend line is a legitimate like-for-like jump in under a year.
Does chatbot-first discovery mean SEO is dead for B2B?
No. The measured finding is about which starting point buyers use more often, and G2 also found 71% of buyers rely on chatbots at some point while still using search. Google remains the larger traffic source by a wide margin; the shift is that the highest-leverage moment — shortlist formation — increasingly happens in the answer layer. You need both: search visibility for volume, answer visibility for shortlists.
How can we tell if chatbots are recommending us?
You cannot observe buyers’ private sessions, so sample instead: run a fixed set of buyer-style prompts (“best X for Y”, “alternatives to Z”) across the major assistants on a regular schedule and log whether you are mentioned, cited or omitted. Treat the result as a frequency distribution, not a ranking — answer sets vary between identical runs. Separately, tag chatbot referrers in analytics to catch the buyers who do click through.
What should sales reps do differently with a chatbot-researched lead?
Assume the buyer arrives late-stage with a machine-built shortlist and provisional conclusions. Ask what their research told them, correct errors with evidence rather than assertion, and move fast — G2 found 69% of buyers changed vendor plans based on a chatbot’s recommendation, so the shortlist is more fluid, in both directions, than it used to be.

The bottom line
The stat on the poster is drifted; the shift underneath it is real. A majority of buyers now reach for a chatbot before Google more often than not, the chatbot is actively rerouting deals, and a third of buyers will purchase from a vendor they discovered inside an answer. The teams that win are visible where answers are formed, measurable where clicks are scarce, and fast when a pre-qualified buyer surfaces. If that last one is your bottleneck — leads arriving hot and cooling in a follow-up queue — that is the gap Zian’s autonomous sales agents are built to close.
