Venduris Fairness Score
52/100Structural friction that costs buyers money or time at renewal.
Evidence basis
Reviewed September 2026
Each category carries the weight set out in the methodology.
Observed from customer contracts and renewal correspondence covering published list pricing and discount structure. Based on paperwork supplied by three or more buyers, cross checked against the vendor's published terms.
Vendor-reported: 73/100
Submitted by the vendor through the structured declaration form.
Datadog auto-renews on terms that make leaving hard: notice measured from a date buyers rarely diarise, and an account conversation before any exit.
Vendor-reported: 52/100
Submitted by the vendor through the structured declaration form.
Vendor-reported. The vendor submitted a declaration covering year over year uplift on renewal quotes. Reviewed against public terms but not independently verified against customer contracts.
Vendor-reported: 38/100
The vendor's own rating for year over year uplift on renewal quotes, broadly in line with what public terms show.
Discounting at Datadog is discretionary: available on multi-year or larger commitments, rarely on a flat renewal.
Vendor-reported: 60/100
Submitted by the vendor through the structured declaration form.
Datadog covers data handling clearly but leaves AI metering and overage behaviour loosely defined.
Vendor-reported: 54/100
Submitted by the vendor through the structured declaration form.
How to read this: the overall figure is a weighted average of the five categories, and one evidence basis applies to the whole card rather than category by category. The vendor completed the full declaration and its own figures are recorded next to ours, category by category. Participation does not move a vendor up the table, and where the two readings disagree both stay published.
Taking part does not raise a score. It changes what we can show our working against.
This score measures commercial treatment at renewal, not product quality. A vendor can be excellent and still price hard.
Venduris tracks your renewal dates, notice windows, and price movements so none of this arrives as a surprise.
