TrustRadius Data Shows Vendors Badly Underrate Peer Trust

The short version

THE SHORT VERSION: TrustRadius's 2026 B2B Buying Disconnect Report finds vendors badly underestimate Peer Trust: they think 41% of prospects talk to existing customers before buying, when the real number tops 50%, and nearly two-thirds among enterprise buyers.

What happened

Demand Gen Report published a Q&A on September 17 with Katie Allison, Director of Leads, Content, and Research at HG Insights, unpacking findings from TrustRadius's 2026 B2B Buying Disconnect Report. The headline finding is a trust plateau: AI tool usage kept climbing through 2026, with 75% of buyers saying AI tools lived up to expectations, but buyer trust in those tools flatlined anyway, breaking a two-year growth streak that vendors had assumed would keep climbing alongside adoption. Underneath that sits a sharper gap: vendors estimate only 41% of prospects speak with an existing customer before purchasing, when the actual figure is over 50%, and closer to two-thirds for enterprise deals. Vendors also underrated how helpful buyers find those conversations, estimating 83% found them useful when the real number was effectively 100%, and the report separately found 16% of buyers admit they aren't even tracking whether their AI investment is delivering ROI, versus vendors guessing that number at just 3%.

Allison's framing is blunt: an AI feature alone isn't a differentiator anymore, because buyers have used enough of these tools to judge them on results, not marketing claims. That shift moves the real battleground for trust off your homepage and onto third-party surfaces you don't fully control, review platforms, customer conversations, and whatever an LLM decides to surface when someone asks it for a recommendation. A founder who assumes product marketing closes the trust gap is optimizing the wrong asset; the data says buyers are already routing around vendor claims entirely and going straight to peers before a rep ever gets a call on the calendar. And because LLMs increasingly summarize exactly this kind of third-party sentiment when a buyer asks for a recommendation, a thin off-site presence doesn't just cost you a skeptical prospect, it costs you the citation itself.

  1. Audit your off-site trust footprint this week
    Search your own company name and see what surfaces on G2, TrustRadius, and Capterra before your homepage does. If those pages are thin or outdated, that is the exact surface buyers are checking before they ever talk to you.
  2. Seed verified reviews from recent closed-won deals
    Ask three customers from your last quarter of closed-won deals to leave a detailed, verified review this month. A handful of specific, recent reviews outweighs a large pile of vague, old ones for both buyers and LLMs pulling citations.
  3. Build a customer-reference pathway into your sales process
    Since over half of prospects already talk to existing customers unprompted, make it easy and sanctioned rather than leaving it to chance. A short list of willing reference customers, refreshed quarterly, turns an uncontrolled risk into a controlled asset.

What to do this week

Pull up your G2 or TrustRadius profile today and count how many reviews you've collected in the last 90 days. If it's fewer than three, send a personal request to your most recently closed customers this week, before the next prospect checks that page and finds it stale.
