Comparison

DecisionOS vs G2

G2 tells you what other buyers thought of a product. DecisionOS tells you why your organisation chose one. The two are complementary inputs into a decision. G2 is an evidence source; DecisionOS is the structure that weights that evidence against your specific criteria, dealbreakers and compliance scope.

TL;DR

G2 tells you what others think. DecisionOS captures what you decide.

How DecisionOS is different

G2 is a read. DecisionOS is a write. Most mature buying teams use both: G2 for peer signal, DecisionOS for the structured record of how that signal was weighted against everything else.

Questions we get about this

Can G2 reviews be cited as evidence in DecisionOS?

Yes. G2 review links can be attached to evidence fields, with the Research Honesty layer explicitly classifying them as user-generated peer evidence.

Reicht G2 als Beweismittel im NIS2-Audit?

Nein. Peer-Reviews sind ein gültiger Input, aber kein vollständiger Audit-Trail. NIS2 Art. 20 verlangt nachweisbare Aufsicht durch das Management mit dokumentierten Kriterien, Stakeholder-Sign-off und Risikobehandlung. G2-Sterne erfüllen keine dieser Anforderungen. DecisionOS erfasst G2-Zitate als Evidenz innerhalb eines vollständigen Memo-Schemas.

Where is DecisionOS hosted?

Entirely in the EU (Hetzner, Nuremberg, Germany). No application data leaves the European Union. Analytics is self-hosted and cookie-free. A data processing agreement per Art. 28 GDPR is in place with the hosting provider.
