Boston-based Modulate has raised $25 million for a voice-intelligence platform that detects deepfakes and scams while analyzing customer conversations and AI-agent behavior. Future Ventures led the round, with Hyperplane and Lakestar participating.

Modulate says its platform orchestrates more than 100 relatively small models. One group extracts signals such as language, tone, emotion, and whether a voice is synthetic; another evaluates intent, policy violations, fraud indicators, and call outcomes. The company argues that this modular design can run without specialized hardware and makes it easier to add a new capability without retraining one large system.

Founded in 2017 by MIT physics graduates Mike Pappas and Carter Huffman, Modulate began with voice-changing technology for games before moving into moderation and enterprise analysis. Its customers use the software alongside call-center and voice-agent stacks, including in regulated settings where companies must monitor compliance. Modulate has about 40 to 45 employees and plans to add roughly 10, while expanding on-premises and on-device options for privacy. The funding supports a crowded field, and claims about nuanced emotion or intent still require careful validation across accents, languages, and real call conditions.
