The problem
Speed decides who wins the lead.
Trial sign-ups and demo requests go cold in hours. By the time someone emails back, the prospect is talking to a competitor.
How CallBooker helps
- Calls every new sign-up the moment your form or CRM sends it through the API or Zapier.
- Asks your qualifying questions (team size, current tool, timeline) and books the demo with the right rep.
- Sends the answers to your CRM through webhooks, so your rep starts the demo prepared.
Your agent books a 20-minute product demo straight onto your calendar.

New lead: Emma Carter · demo request
From your website form
Hi Emma, it’s Ava from Lumen. You just asked for a demo, got a minute?
Wow, that was fast. Sure.
How are you tracking your pipeline today?
Spreadsheets. It’s a mess with five reps.
That’s what Lumen fixes. Thursday at 2 PM or Friday at 10 AM for a demo?
Thursday at 2 works.
