What is IntrLume?
IntrLume is the AI that owns the follow-up. It calls, WhatsApps and emails your leads. In a routine, it decides each next step after every conversation, and keeps going until they answer or your limit is reached. It is four AI agents for customer calls and chats. The AI Calling Agent makes and answers phone calls around the clock; the Chat Agent answers and follows up on WhatsApp; the Follow-up Agent plans each customer's next call or message and keeps going until there's an answer; the Intelligence Agent reads every call and chat and tells the business why customers say yes or no. New leads are called within seconds of arriving, inside the business's calling hours; inbound calls are answered at any hour from the business's own documents; bookings, surveys and reminders are handled on the call. Every conversation is recorded and transcribed, and for leads from Zoho CRM or HubSpot the outcome, a summary and the recording link are written back to the record. It is used for sales, support, surveys and reminders, and appointments, in education, real estate, healthcare, financial services, home services and marketplaces.
You paid for every enquiry. Half never hear from you twice.
Teams call once, maybe twice, then move on to the newest lead. Buyers decide weeks later, and they buy from whoever is still there. (Velocify research: half of leads are only called once. US data, directional.)
The AI that owns the follow-up.
It calls, WhatsApps and emails your leads. In a routine, it decides each next step after every conversation, and keeps going until they answer or your limit is reached.
1 in 4 people pick up only when you call again.
- 27% of people who missed two calls picked up on a later one

Can remember past calls, chats and emails.

Where follow-up decides the sale.
- Universities — 44% of enrolments came from the 11% of students who enquired more than once. (Meritto Enrollment Index Trends Report, April 2025)
- Real estate — 26 days from first enquiry to booking. (ANAROCK, H1 FY25, via Outlook Money)
- Clinics — 186 IVF centres at one chain by July 2025, while its cycles stayed flat at 42,622 a year. New clinics open faster than they fill. (ICRA on Indira IVF, FY25)
The AI plans. Your rules overrule it.
- Calls only in the hours you set — In your contact’s local time where the law requires it
- Do-not-call list checked before every dial — If the check fails, the call doesn’t go
- Every AI follow-up WhatsApp checked before it goes — A second AI checks it, or nothing is sent
- Every change your team makes is logged — Who changed what, and when
Works with your CRM
IntrLume works with Zoho CRM and HubSpot today. New leads from either are called automatically, and each call's outcome, a summary and the recording link are written back to the record. From Zoho CRM a team can also start a call on a lead or run a campaign over a saved view.

Frequently asked questions
What is IntrLume?
Four AI agents for your customer calls and chats. The AI Calling Agent makes and answers calls, the Chat Agent answers and follows up on WhatsApp, the Follow-up Agent keeps going until there’s an answer, and the Intelligence Agent tells you why customers say yes or no.
What is speed to lead?
How fast a new lead gets its first call. In a 2011 Harvard Business Review study, firms that tried to reach a lead within an hour were nearly seven times as likely to qualify it as firms that tried an hour later. IntrLume calls within seconds, inside your calling hours.
Is it for business owners or sales teams?
Both. Owners use it to answer every lead without hiring for it. Sales teams hand it the first call, the qualifying and the redials.
What does it cost?
You pay for what you use, with no long-term contract.
What do you need from us?
For old leads, a spreadsheet: name, number, what they asked about. For new ones, connect your form, CRM or phone line. No new tool for your team.
Will it sound like a robot reading a script?
No. You pick the voice and pace, and it answers from your own policies. When it doesn't know, it says it'll check.
How many times does it try a lead?
For a new lead, up to ten times, hours apart, for up to a month — only inside your calling hours. It stops as soon as they pick up.
What happens when someone is ready to buy?
Your team sees them marked qualified, with what they asked and what was agreed, so your first call picks up where ours left off.
Which systems does it work with?
IntrLume connects to Zoho CRM and HubSpot, website forms and Google Ads lead forms, and new enquiries from them are called automatically. Calls to your existing business number are answered, and WhatsApp messages can be too. When an enquiry came from Zoho CRM or HubSpot, each call's outcome, a summary and the recording link are written back to the record. Leads from lemlist, LinkedIn or any other tool arrive through your CRM or a webhook, for example via Zapier.
