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.
