Refrens is a B2B SaaS platform serving 150,000+ businesses across 170+ countries, offering invoicing, accounting, payments, and business operations tools. Every month, tens of thousands of new users sign up on the platform. While high-intent users were actively engaged by the sales team, a large portion of new users remained unqualified not because they lacked intent, but because manual outreach could not scale. This created a critical gap: lead coverage, not lead generation. To solve this, Refrens built a low-latency, real-time Voice AI Agent using VideoSDK, enabling automated conversations that qualify users instantly after signup and route high-intent leads to sales.

CHALLENGE

Scaling Lead Qualification Without Manual Bottlenecks

  • Limited Lead Coverage: A large portion of new users remained unqualified due to manual outreach limitations, leading to missed opportunities.
  • High Operational Overhead: Sales teams could not scale to handle thousands of new signups every month.
  • Latency in Voice Automation: Traditional voice bots introduced delays (2–3 seconds), resulting in poor user experience and call drop-offs.
  • Unstructured Qualification Process: Lack of consistent data capture made it difficult to prioritize high-intent users effectively.
  • Inefficient Sales Routing: Without real-time qualification, sales teams spent time on low-intent leads.

"VideoSDK helped us turn voice into a programmable, real-time system. We can now qualify thousands of users automatically and route only high-intent leads to sales something that wasn’t possible with manual workflows."
