Case Study: Synthflow Voice Agents Handle 500K+ Calls per Month

A top US-based CRM and sales automation platform serving thousands of businesses across industries. With over $100M in annual revenue, this company provides advanced tools for managing customer relationships, marketing automation, and sales pipelines – all within a unified platform.

In 2025, they expanded their product suite with embedded voice AI to help clients better capture leads and handle support.

The Challenge

• Enterprise-grade security and compliance (SOC2, HIPAA, GDPR, PCI-DSS)
• No-code agent deployment for rapid rollout
• Full API support for advanced customization

With no additional internal development required, the CRM provider was able to offer a fully branded voice automation feature to its customers – instantly expanding product value and opening a new revenue channel.
