Claim
In a UserEvidence survey of 619 B2B buyers, 51% rated specific customer ROI stats the most trustworthy form of evidence. This is the proof type buyers want most and is the hardest type to get on the record. PMMs who solve the supply problem on this proof type win disproportionate trust in the buying cycle.
Mechanism
Generic capability claims are pattern-matched to vendor copy and discounted. ROI stats from named customers signal that someone with skin in the game made the same bet and got a measurable outcome. The trust premium scales with specificity and named-source attribution.
Conditions
Holds when:
- The buyer is B2B and outcome-accountable (CFO scrutiny, ROI defense).
- A named customer with a measurable result will go on the record.
Fails when:
- Buyer is consumer or self-serve at low ACV — proof types shift toward reviews.
- Customers can't share due to legal, secrecy, or attribution gaps (use anonymous benchmark — see related).
Evidence
"UserEvidence surveyed 619 B2B buyers and 51% said it's the most trustworthy form of evidence."

Signals
- Marketing teams rank proof-point types and budget customer-evidence acquisition explicitly.
- Case studies lead with quantified ROI in the headline, not "trusted by X" logos.
- PMMs partner with CS to surface ROI stats from QBRs.
Counter-evidence
No opposing view in current corpus.
