THE PRODUCT

The whole outbound loop, on autopilot.

Design a pitch, launch a campaign, and let Boltun call, listen and improve — a closed loop that gets sharper with every conversation.

STEP 01 · DESIGN

Describe your offer. Get a working agent.

Chat with Robert, Boltun's prompt designer. It interviews you about your offer, then drafts the opener, discovery questions, objection handling and close — and extracts a production-ready system prompt automatically.

Auto-extracts prompts straight from the conversation
Editable markdown, versioned per campaign
Tunes tone and TTS expressiveness to your chosen voice

STEP 02 · DIAL

Import a list. Hit start. Walk away.

The auto-dialer places concurrent calls over Telnyx SIP, respecting each contact's local calling window. Failed numbers retry automatically until they connect or hit their attempt limit.

CSV import with phone validation and E.164 normalization
Per-contact timezone across all 448 IANA zones
Concurrency and daily-window limits you control
STEP 03 · REFINE

It reads the room, then rewrites itself.

After a batch of calls, Boltun pauses and analyzes the transcripts — what worked, what stalled, where prospects dropped. It proposes a sharper script and, once you approve, resumes calling with it.

Automatic pause & review after N completed calls
Per-call transcript analysis and scoring
Nothing changes without your approval

− "Hi, do you have a minute to talk about onboarding?"
