Why teams switch to Sempera
AI-native, not AI-bolted-on
Sempera was built as an AI voice agent platform from day one. Five9 adds AI features on top of a human-agent routing platform. The architecture matters.
Per-minute vs per-seat
Five9 charges $149-$229/agent/month regardless of call volume. Sempera charges $0.11 to $0.14/min only for calls the AI handles. No idle seat costs.
Instant scaling
Add AI capacity in seconds for seasonal spikes. With Five9, scaling means hiring and training human agents over weeks or months.
100% compliance consistency
Sempera delivers mandatory disclosures on every call. Human agents miss disclosures. The risk difference is measurable.
