Voice AI Agent Improves Lead Qualification Rate by 40% Driving Faster Conversions and Maximizing ROI

Challenge

Interakt, a Jio Haptik product, had quickly become a go-to WhatsApp-first engagement platform for small-to-medium businesses, across the globe, helping them automate conversations, capture leads, and drive sales, all within WhatsApp. With over 300,000 monthly visitors and a constant influx of demo requests, the team faced an operational challenge at scale.

Research shows that responding to a prospect within the first five minutes can boost conversion rates by up to 400%. While Interakt prided itself on maintaining the highest standards of responsiveness, meeting this benchmark consistently proved difficult for their lean, fast-moving team.

The challenge was compounded by language barriers, as hiring agents fluent in multiple languages and well-versed in Interakt’s offerings proved difficult. Add to that the absence of 24/7 support, and prospects often had to wait for timely assistance.

With customer experience at the heart of everything we do, resolving this issue quickly was critical.

Solution

To overcome these challenges, we turned to our own innovation, Haptik’s Voice AI Agents. 

Voice AI Agents enable natural, human-like voice conversations between businesses and prospects, available anytime and anywhere. 

Within just 3–5 days, the system was live, handling initial outreach for demo sign-ups on Interakt’s website.

• Instant Callbacks: Calls initiated within 15 minutes of lead submission.
• Smart Conversations: Qualifying questions asked and demo data captured automatically.
• Multilingual Support: Prospects engaged in their preferred language.
• Centralized Data: All interactions logged in one place for easy access.
• Seamless Handoffs: Only qualified leads passed to sales teams.
  
  

What began as an internal experiment quickly became a proof point for how AI-powered automation can drive responsiveness, personalization, and efficiency at scale. As a result, prospects experienced faster responses, clearer guidance, and a frictionless demo booking journey, significantly improving overall customer satisfaction. At the same time, our sales and BDR teams could focus on high-impact deals, accelerating movement across the pipeline.

Outcome

Lead qualification efficiency saw a clear upward trajectory, with call-to-qualified conversion improving from 14% in July 2025 to 19% in September 2025 surpassing the industry benchmark of 15 - 17%. The week of August 20th marked a peak in performance, achieving a 40% qualification rate against a 30% target, underscoring the tangible impact of automation on lead quality and sales velocity.

Future and Next steps

Haptik is committed to continuously enhancing the capabilities of its Voice AI Agents to deliver even more impactful results. The upcoming initiatives include:

• Enhanced AI Models: Deploying improved models to further increase data capture rates and lead qualification accuracy.
• Natural Indian Voices: Introducing more Indian voice options that sound more human-like and improving customer engagement.

• Intelligent Call Handling:
• a) Automatically detect voicemails, cut the call, and retry at a later time to optimize efficiency.
• b) Rescheduling calls automatically if a customer attends the call and indicates they are busy.
• Advanced Analytics & Insights: Leveraging improved transcripts and analytics to understand what drives engagement, identify areas of improvement, and continuously optimize conversation flows.

These enhancements will not only make interactions more natural and efficient but also provide actionable insights for sales and customer experience teams, driving higher conversion rates and better overall customer satisfaction.
