Best AI agents for support leads

Heads of CX, support managers, ops directors.

Customer support is the most measured category in AI agents — deflection rates, CSAT, time-to-resolution all show up cleanly. Done right, deployments routinely deliver 60–75% tier-1 deflection in chat.

Pick the right tier for your knowledge-base maturity and channel mix. Sierra for enterprise white-glove, Decagon for mid-market chat, Parloa for voice-heavy contact centers.
