Trusted by B2C Leaders Who Get It

“Convin has transformed the way we manage quality, collaboration, and communication.”
Before Convin, our QA process was scattered across Google Forms and our CRM, making audits, updates, and insights extremely time-consuming. With Convin, everything is now centralized—audits, PKTs, and process updates are easily accessible on one platform. We can make instant changes to audit forms without tech support, and all call recordings are readily available for review and insights. The ability to fill both Audit and Governance Forms simultaneously has boosted QA efficiency, while Team Leads can now track compliance independently.

“It's like having a virtual assistant for every rep and manager.”
Convin.ai captures and analyzes every customer interaction - voice, video, and email. With Convin, we’ve eliminated scattered insights, improved sales performance, accelerated onboarding, and even automated CRM updates. We no longer miss a single insight.

Convin.ai has transformed our audit process.
The audit dashboard gives us real-time insights with multiple metrics, making it easier for agents to stay updated on manual audits. What used to be time-consuming manual work in Google Sheets is now streamlined, efficient, and insightful thanks to Convin.ai.

Before Convin, we lacked visibility into why leads were being closed incorrectly, which made it difficult to identify missed business opportunities and impacted both conversions and forecasting accuracy. With Convin’s AI-driven insights, we can now spot genuine buying intent, recover lost leads, and take timely action. This has significantly improved our sales efficiency and reduced revenue leakage. A major advantage has been the alignment it’s created across sales, quality, and business teams- everyone now works with the same reliable data.

Before Convin, our quality reviews were entirely manual and limited to a small sample of calls, making it hard to identify patterns or spot missed sales opportunities. With Convin, we can now analyze every call automatically and gain complete visibility into how agents handle leads. The platform helps us flag missed opportunities, provide targeted feedback, and ensure consistent, objective QA scoring. Our reviews are now faster, more accurate, and far more insightful.

Before Convin, it was difficult to link quality insights with training outcomes, making it hard to measure how coaching impacted performance and slowing down new agent ramp-up. With Convin, we can now quickly identify skill gaps that affect conversions and deliver targeted, effective coaching. Training has become more focused, and we’re excited to explore Convin’s LMS capabilities to integrate quality and learning on a single platform. The results have been tangible in both agent performance and efficiency. The Convin team has been highly responsive, open to feedback, and proactive in tailoring the platform to our needs.
