The problem
Leads go cold while they wait for a call back.
People fill in your form while they're thinking about you. Every hour that passes, they compare, forget, or book with whoever called first.

How it works
From form to meeting in under a minute.
Step 1
A lead comes in
From your website form, your CRM, Zapier, or a list you upload.
Step 2
Your AI agent calls in seconds
It introduces itself, answers questions, handles objections and qualifies the lead.
Step 3
The meeting lands on your calendar
Booked live during the call, with a reminder sent to the lead. You just show up.
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.

Objection handling
It doesn’t give up at the first “no”.
Your agent answers the brush-offs real reps hear every day: it asks one question, answers briefly, and pushes back once, politely. A real no is respected. Add your own answers for objections specific to your offer.
- “Just send me an email”
- “I’m not interested”
- “I’m busy, call me later”
- “We already use something”
- “How much does it cost?”
- “Are you a robot?”
If someone asks, the agent says it’s an AI assistant. If they ask not to be called, it marks them “do not call”.
Example call
Hi Liam, it’s Leo from Lumen. You downloaded our pipeline report last week, is now a bad time?
Honestly I’m busy. Just send me an email.
Of course. So it’s actually useful: are you the one choosing reporting tools for your team?
Yeah, more or less.
Then instead of another email, 15 minutes with our team would show you your own numbers. Tuesday morning?
Fine. Tuesday at 9.
