General Catalyst Backs Otter.ai's Voice AI Ambitions with $320M Growth Investment

‍Mountain View, Calif. (October 20, 2026) - Otter.ai, the company behind the leading AI notetaker and conversational knowledge platform, today announced the closing of $320 million in growth financing from General Catalyst’s Customer Value Fund (CVF). The new capital will accelerate the next phase of Otter’s enterprise growth, go-to-market strategy, international expansion, and product innovation as Otter builds toward becoming the definitive knowledge layer for enterprises, where every conversation is captured, connected, and turned into action.

Otter is already trusted at scale: more than 40 million users worldwide, including teams at over 86% of the Fortune 500. Across more than 1 billion meetings transcribed, Otter has generated over $1.5 billion in customer ROI through time saved.

This momentum, along with General Catalyst’s investment, supports Otter’s mission to become the voice system of record for all enterprises.

Built on a foundation of industry-leading Automatic Speech Recognition (ASR) accuracy and the most accurate speaker identification, Otter turns meeting context into organizational knowledge powering significant productivity gains for organizations across industries including sales, to consulting, education, financial services, professional services, and media.

“This financing from General Catalyst is a powerful vote of confidence in what we’re building at Otter, and we’re excited for the next phase of growth it will drive,” said Sam Liang, Otter.ai CEO. “This will fuel our next chapter, enabling us to build enterprise agentic workflows that bring more advanced, intelligent AI to teams everywhere and push toward a future where voice becomes the backbone of enterprise productivity.”

"Voice is one of the biggest untapped opportunities in enterprise AI, and Otter is at the forefront of it - a conviction that's only deepened watching Otter's growth," said Pranav Singhvi, Partner and Co-founder of CVF, General Catalyst. "When Otter enables enterprises to capture critical voice data and turns it into actionable business insights, teams move faster, decisions get sharper, and productivity compounds across the organization, and that's why it's a strong partner for CVF."
