Your agents take 80 hard calls a day. Prepare them for the 81st.
Refund demands, retention saves, cancellations, hostile escalations — your reps practice the worst-case calls against an AI that pushes back, before they pick up the phone.

Quality assurance after the fact is too late.
Your QA team catches a bad call after the customer has already hung up. MHB catches it 200 simulated calls earlier — before it costs you a renewal.
Agents complete a full scenario rep faster than a coaching session. Pre-shift drills become realistic.
No clicking through scripts. Agents speak; the AI replies in voice. The friction matches a live call.
De-escalation, empathy, policy accuracy, save-the-customer — each scored separately. QA leaders see where to coach.
Three call types your team faces every day.
45-second samples — different conversation types, the same AI engine pushing back behind the scenes.
"I want a full refund — now"
Frustrated long-tenure customer threatens to cancel and post about it. Agent must de-escalate without giving away the policy.
The competitor is cheaper
Customer calls to cancel because a competitor undercut you. Defend value, not price. Find the real reason.
"Put me on with your manager"
Tier-1 agent gets an aggressive escalation request. Hold the line, gather facts, set expectations before transferring.
"I've been struggling with difficult conversations my whole life. It's never been easy to say the right thing at the right time. I built MHB to be the gym I wished I had. Practice speaking now — and help your future self when the moment arrives."
