A real call. Live.
Click play. The transcript is from an actual outbound call our SDR agent ran this week. Latency, tone, transfer-on-intent - all real.
- Knowledge-grounded. The agent reads the prospect's CRM record and your pricing page before it speaks.
- Transfer-on-intent. When the prospect says "I want to talk to a human," they're transferred - with full context already passed.
- Auto-logging. Transcript, intent classification, deal stage update written before the call ends.
- Interruption-safe. The agent stops talking the moment the caller starts. No "as I was saying."
Swap providers per agent.
Different agents have different needs. Your support agent might want Deepgram + Cartesia + Claude for warmth and recall. Your SDR might want OpenAI Realtime + ElevenLabs + GPT for speed.

Answer every call - including the 11pm ones. Qualify, route to human on intent, book on the calendar.
Run sequences with a calling step. The agent dials, reaches the prospect, qualifies, and books a human follow-up.
Reduce no-shows. The agent calls confirmations, reschedules, takes payment authorization.
Knowledge-grounded answers to FAQs, account lookups, status checks. Escalates to a human on emotion or complexity.
For high-volume inbound forms. The agent calls within 90 seconds of submission, qualifies, and writes the deal.
Lapsed customers, churned subscribers, expiring contracts. The agent calls with a one-time offer and books a save.
