Boston-based voice intelligence startup Modulate has raised $25 million in new funding to expand its platform. The platform utilizes an array of small models to provide enterprises with transcription, emotional analysis, deepfake, and AI music detection, as well as policy enforcement for voice agents in regulated industries.
The funding round was led by Future Ventures, with participation from Hyperplane and Lakestar. According to PitchBook data, the startup had previously raised $41 million in funding at a $170 million valuation prior to this round.
Modulate operates more than 100 models categorized into two main sections: signal extraction models, which understand vocal emotion, tone, language, and synthetic voice determination, and analysis/detection models, which identify intent, such as customer goals, rule violations, or scam attempts. According to co-founder Carter Huffman, the company's use of smaller models allows for operation without specialized hardware or massive compute resources, which can be crucial as token costs increase.
The company's technology is currently being used to monitor cyberattacks via voice calls and to assess the quality of customer service calls by monitoring AI agent responses. Modulate is also working to increase its on-premises and on-device deployment capabilities to enhance privacy. The startup currently employs 40–45 people and plans to add approximately 10 more staff members to its model-building team in the coming months.
