Rufen
One platform

Four kinds of calls, one platform.

Whatever the call looks like, Rufen handles it.

Inbound

AI receptionist

Answer every call. Triage intent, book onto your calendar, escalate when it matters.

Outbound

Outbound campaigns

Dial lists at your pace. Surveys, reminders, follow-ups, lead qualification.

New

One-shot calls

Send the AI to make a single call — get a quote, confirm availability, ask one question.

Hybrid

Human handoff

AI handles the routine. When it gets complex, it transfers cleanly with full context.

One-shot calls

Need a phone call made? Send the AI.

Type the question, pick the number, get the answer. No agent setup, no scripts — disposable agents for one-off tasks.

Real Calls dashboard

Watch every active call live. Transcript, sentiment, hangup reason, recording — all in one screen.

AI as a teammate

AI on your team — not instead of it.

Rufen handles the routine. When a call needs a human — a complaint, a complex booking, a regulated conversation — it transfers cleanly with the full call context.

Handoff demo

  • Smart trigger detection

    Hand off by intent, sentiment, tool failure, or on caller request — your rules.

  • Full context handoff

    Human picks up with the transcript, sentiment, and intent already in front of them.

  • After-hours fallback

    Outside business hours, Rufen handles it solo. Same agent, same script — no missed call.
