Real Estate Developer Kleindienst Group Scaled Lead Outreach 10X with Voice AI

Overview

As one of the first real estate groups in the MENA region to create an in-house AI division, Kleindienst Group’s mission was clear: use automation to enhance human productivity, not replace it. The challenge? Traditional tele-sales could only handle 60–80 calls a day per person — leaving most leads untouched and slowing down conversions.

By partnering with Synthflow, the company deployed human-like Voice AI agents that qualify, schedule, and route calls around the clock, freeing sales teams to focus on closing deals.

Problem

Kleindienst Group’s sales team needed extensive resources to qualify tens of thousands of leads across multiple regions. Manual outreach limited daily call volume and caused delays in follow-ups, leading to lost opportunities and higher labor costs.

Each sales representative could handle only 60–80 calls a day, leaving the majority of the 250K-plus leads untouched.

“We have a growing database of 250,000+ leads,” says Vikas Jaswani, Head of AI Initiatives. “Expecting humans to reach them all wasn’t realistic — we needed something faster, smarter, and scalable.”

Solution

With Synthflow’s real-time Voice AI, Kleindienst Group automated the full qualification cycle — from first call to meeting booking.

“Integration was incredibly fast — our in-house CRM connected to Synthflow in under an hour,” said Jaswani. This plug-and-play approach allowed their AI agents to go live within days and rapidly scale to over 1,000+ calls daily.

The Voice AI now:

Qualifies and routes new property inquiries automatically

Handles receptionist tasks and appointment scheduling

Powers internal sales-training roleplays for the team

“From start to end, Synthflow’s support has been exceptional,” said Jaswani. “They’ve helped us move faster than we thought possible — and the call quality is still ahead of the market.”

When management saw how many calls we completed in a single day, the meeting literally stopped. They said, ‘Wow, that’s impressive — scale it up.’

The Results

The implementation of Synthflow’s AI agents led to a measurable leap in productivity and scale across Heart of Europe’s operations.

30K+ Calls per Month‍

The AI agent processes over 30,000 outbound and inbound calls monthly, scaling outreach across a database of 277,000+ contacts without performance degradation or capacity limits.

100% Call Coverage (Including After Hours)‍

All inbound calls are answered, including after-hours and peak-time overflow — eliminating missed opportunities when human agents are unavailable or lines are busy.

~1% Warm Lead Rate‍

From a largely unqualified dataset, the AI identifies ~1% high-intent prospects, filtering noise and surfacing actionable leads for the sales team. Voice-personalized outreach contributes to consistent meeting bookings at ~1%.‍

~90% Cost Reduction‍

Automation replaces the workload of approximately 10 tele-sales agents, reducing operational costs to ~10% of a human-led setup while maintaining higher output and consistency

‍Conclusion

By implementing Synthflow’s Voice AI platform, Kleindienst Group has reimagined real estate outreach. The result: faster qualification, better engagement, and a scalable foundation for AI-driven innovation.

With 150 AI agents planned for deployment and new use cases like AI-powered sales training underway, Kleindienst Group is setting a new benchmark for how luxury developers connect with customers.

“We even explored becoming Synthflow’s distributor in our region — that’s how much we believe in the technology,” said Jaswani.
