Pindrop

Market position

Positions itself as the only platform addressing AI identity fraud across both contact centers and virtual meetings. External recognition cited includes TIME's 10 Most Influential Software Companies of 2026, a TIME Best Invention 2025 award for Pindrop Pulse, and an Inc. Best in Business 2025 award. Forge lists a $977.29M post-money valuation from the December 2018 Series D and categorizes the company under enterprise software/cybersecurity.

Combines multiple signals (audio liveness, video liveness, geolocation, voice biometrics) rather than a single point solution; passive authentication that avoids added friction for legitimate callers; a large patent portfolio (300+ patents); coverage of both contact center and virtual meeting channels; and claimed 99% AI audio detection accuracy independently verified by NPR.

Technology

The platform analyzes live audio and video for AI-generated artifacts and anomalies, combining audio liveness detection, video liveness detection, geolocation intelligence and voice biometric authentication into a single risk signal. Pindrop states Pulse for Meetings can flag a synthetic participant within two seconds of speech and that its audio engine detects synthetic voices with 99% accuracy. Earlier core technology includes Phoneprinting, which identifies devices acoustically to detect fraud, and Pindrop Protect, which factors location, behavior, audio, voice, time of day and device type to confirm a caller's identity. The company reports over 300 patents across audio analysis, biometrics, deepfake detection and identity authentication.
