Case Study: Aizee Boosts Response Rates by 30% Using Synthflow

413

Aizee is a provider of AI solutions helping businesses manage sales, support, and client interactions 24/7; on a mission to prepare companies for future with a suite of tools and workshops on AI deployment.

Challenges

Aizee had a database of cold leads previously interested in AI workshops, but they may be aged and with low engagement. Cold calling or mass emailing posed risks as a waste of time and resources.

The team needed a low-risk, high-impact approach by testing a small batch to efficiently re-engage and qualify leads still showing interest.

Solution

Rather than relying on traditional call methods, Aizee used Synthflow voice AI agents to implement a smart, automated outreach strategy while maintaining a personalized touch.

A day before calling, a marketing email was sent to the selected cohort. The team then called 60 leads to test Voice 2.0 and refine messaging. The results exceeded expectations, boosting engagement and renewing confidence in lead reactivation.

“Synthflow completely changed the way we approach lead engagement: instead of cold calls with uncertain outcomes, we had a structured, AI-powered approach that delivered 30% responses and increased reactivation by 10%.

Thanks to Synthflow, we turned old leads into high-quality prospects faster than we expected,” said James Mulholland, CEO and Co-Founder at Aizee.ai.

Results

Aizee reactivated a dormant database of 7,000 leads and maximized conversion rate to sell their online education programme with Synthflow voice AI agents:

60 Concurrent Calls – Automated outreach launched instantly, re-engaging dormant leads at scale, without adding pressure on the sales team or disrupting workflows
+30% Response Rate – 1 in 3 leads actively responded, significantly outperforming traditional cold calling with real conversations, not just callbacks.
+10% Increased Reactivation ‍ – AI Agent quickly qualified leads for time availability and up-skilling budget, resulting in a list of warm and hot prospects ready for an immediate follow-up by a sales rep.
7-minute Phone Call ‍ – The AI agent sustained rich, multi-turn discussions with prospects, proving its ability to handle nuanced conversations and low-latency responses in real time.

Conclusion

Aizee’s success with Synthflow’s approach proves that AI-powered outreach can re-engage cold leads, maximize efficiency, and deliver tangible results. Following this success, Aizee is now scaling its outreach across new verticals and audiences.
