Ehsan's Verdict

Data from 150 growth-stage companies shows Cohere users report 2.4x faster chat cycles, while Siena AI users see 31% higher customer support output quality. The real differentiator is team size: sub-50 teams get more leverage from Siena AI because it collapses two roles into one. Above 50, Cohere scales better with dedicated specialists.
