An AI voice platform that handles inbound reception and outbound sales calls for small businesses, acting as "revenue insurance" by capturing every missed opportunity.

Small businesses lose a large share of incoming sales opportunities when calls go unanswered. This client wanted to build a "revenue insurance" platform using conversational AI to handle inbound reception and outbound sales calls seamlessly.

Challenge

Traditional phone trees frustrate callers, and staffing 24/7 human receptionists is cost-prohibitive for small businesses. The platform needed ultra-low-latency conversational voice agents, real-time data synchronization, secure multi-tenant authentication, and a unified API gateway to connect with no-code automation tools like Zapier and Make.

Solution

We developed a unified backend and frontend architecture featuring:

  • Unified API Gateway: A high-performance Hono API gateway hosted inside Next.js 16, decoupling API logic for future portability.
  • Real-Time Serverless Database: Powered by Convex for instant data synchronization, live call logging, and reactive UI updates.
  • State-of-the-Art Voice AI: Deep integration with Vapi.ai for hyper-realistic, low-latency voice synthesis and speech-to-text.
  • Secure Multi-Tenancy: Robust tenant isolation and secure onboarding powered by Clerk and Stripe.

Results

The platform went from concept to production in 10 weeks. It now automates tens of thousands of inbound calls, recovering revenue that would otherwise have been lost to missed calls, while maintaining a high customer satisfaction rating.
