Real Estate Firm Increased Lead Follow-Up Speed by 60%

The Challenge

A Noida-based real estate firm was losing 40% of inbound leads because agents couldn't follow up within the critical first 5 minutes. Their team of 15 agents was stretched thin during peak hours, leading to missed opportunities.

Our Solution

We developed an AI calling agent using voice AI that automatically calls new leads within 30 seconds of form submission. The agent qualifies leads through a natural conversation, schedules site visits, and only transfers qualified leads to human agents.

How We Built It

  1. 1

    Mapped the lead qualification process used by their top-performing agents into a structured conversation script with branching logic for different prospect responses.

  2. 2

    Built a voice AI pipeline with real-time speech-to-text, LLM-based conversation management, and text-to-speech output with natural-sounding Indian English and Hindi.

  3. 3

    Integrated with their CRM (Zoho) so the agent could read lead details before the call and write back the qualification results, call transcript, and next action.

  4. 4

    Set up automatic call triggering: when a new lead form was submitted, the system initiated the outbound call within 30 seconds via a telephony API.

  5. 5

    Designed a smart routing layer: leads with a high qualification score were transferred to a human agent immediately; others received an automated follow-up sequence.

  6. 6

    Deployed a dashboard showing call outcomes, qualification scores, and conversion tracking so the sales manager could monitor performance.

Integration & Architecture

The AI calling agent was wired into the existing Zoho CRM via its REST API. When a new lead was created in Zoho, a webhook triggered the calling pipeline. The call result — qualification score, schedule, transcript — was written back to the same CRM record so agents had full context.
