Smartcat, a language AI platform, partnered with Synthflow to enhance its lead qualification process using Voice AI Agents.

The collaboration led to a significant increase in answered calls, lead reactivation, and closed sales, while reducing booking costs by 70%, enabling Smartcat’s sales team to focus on high-value conversations and boost overall efficiency.

Challenges

Smartcat, a leading language AI platform for enterprises, wanted to increase the number of product demos booked while improving cost efficiency per scheduled meeting.

Traditional methods of using human callers had plateaued in performance, especially during the early stages of the lead qualification process.

Solution

Smartcat partnered with Synthflow to implement Voice AI Agents and conducted an A/B study to compare their performance vs. human callers. The study revealed thatSynthflow’s Voice AI Agents excelled in the early stages of lead qualification by:

Initiating calls at a higher frequency.
Maintaining consistent follow-ups, leading to a higher rate of answered calls.

By automating repetitive and time-consuming tasks, Smartcat’s sales team could now focus on complex and high-value sales conversations.

Ultimately, this resulted in an effective hybrid sales strategy combining Synthflow’s Voice AI solution with human expertise.

“Synthflow’s Voice AI Agents help us book more demos faster. We increased the conversion rates in the top of our lead pipeline: the number of contacts dialled by 31% and the number of answered calls, 24%. With more people dialled, we re-focused the sales team on high-value signals,” said Daniel Lefanov, Implementation Manager at Smartcat.

Results

The integration of Synthflow’s Voice AI Agents into Smartcat’s lead qualification workflow delivered measurable improvements across key performance indicators:

70% Booking Cost‍ – Optimized outreach reduced booking costs which dramatically improved ROI of outbound efforts.
+24% Answered Calls‍ – Substantial lift in answered call rates, thanks to persistent, timely follow-ups by AI agents.
15% Lead Reactivation‍ – Increased lead reactivation, as the AI system engaged dormant contacts at scale with personalized, consistent outreach.
+15 Closed Sales – Higher conversion to demos and sales, driven by more efficient qualification and seamless handoff to the sales team.

Conclusion

Smartcat’s partnership with Synthflow demonstrates the power of combining Voice AI with human selling. By offloading repetitive, early-stage outreach to AI agents, they achieved both scale and efficiency without compromising personalization.

The outcome: a more productive sales team, a better-qualified pipeline, and a cost-efficient path to growth. As AI continues to transform enterprise workflows, Smartcat’s hybrid sales strategy serves as a model for forward-thinking go-to-market teams.
