Modulate

Modulate is a voice AI company that provides audio-native intelligence for fraud detection, online safety, and compliance across voice interactions. The company's core technology is Velma, an Ensemble Listening Model (ELM) architecture that is 2x-4x more accurate than LLMs at conversation understanding, ranked #1 on Hugging Face's transcription benchmark and deepfake detection leaderboard with 98.9% accuracy. Modulate offers two primary delivery models: the Modulate Platform for enterprises, which listens to every conversation and surfaces risks including fraud, churn, compliance violations, and abuse without requiring engineering; and the Modulate API for developers, providing audio-native models for building custom systems. The API suite includes five model families: Detect (deepfake detection, AI music detection, music and speech detection, language detection, emotion detection, accent detection, voicemail detection), Transcribe (multilingual and English fast transcription, medical transcription), Redact (PII and PHI redaction from audio and transcripts), and Triage (Velma Triage for surfacing risks, ToxMod Triage for trust-and-safety moderation). The platform detects over 150 key behaviors spanning fraud detection, AI agent guardrails, trust and safety, customer retention, human agent welfare, and compliance and risk monitoring. Modulate serves industries including CX and contact centers, financial services, gaming and social, and IT and helpdesk, with customers including Activision. The platform is ISO 27001 compliant, HIPAA-compliant, and built to operate within GDPR, CCPA, and EU AI Act requirements, never training on customer conversations. Founded in 2017 and headquartered in Cambridge, Massachusetts, Modulate has raised $32.0M in Series A funding from investors including Hyperplane, Lakestar, EVERBLUE ESPORTS VENTURES, Galaxy, Old Silver VC, and Crush Ventures.
