Otter.ai, maker of an AI notetaker and conversational knowledge platform, announced the closing of $320 million in growth financing from General Catalyst’s Customer Value Fund (CVF) on October 20, 2026. The company said the new capital will accelerate the next phase of its enterprise growth, go-to-market strategy, international expansion, and product innovation.
Otter framed the financing around its stated ambition to become the definitive knowledge layer for enterprises, where every conversation is captured, connected, and turned into action, and its mission to become the voice system of record for all enterprises. The company said the platform lets teams prepare with better context, make faster decisions, and act on discussions after meetings end.
“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’s co-founder and 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.”
Otter reports more than 40 million users worldwide, including teams at over 86% of the Fortune 500. The company says it has transcribed more than 1 billion meetings and generated over $1.5 billion in customer ROI through time saved. It credits its in-house automatic speech recognition and speaker identification technology, which it describes as industry-leading, and says the platform turns meeting context into organizational knowledge for customers in sales, consulting, education, financial services, professional services, and media.
“Voice is one of the biggest untapped opportunities in enterprise AI, and Otter is at the forefront of it,” said Pranav Singhvi, Partner and Co-founder of CVF at General Catalyst, adding that his conviction has deepened as he has watched Otter’s growth. Singhvi said Otter’s ability to turn captured voice data into actionable business insights makes the company a strong partner for the fund.
How the Customer Value Fund Works
General Catalyst lays out the mechanics of its Customer Value strategy in The Unbundling of “Growth” Equity, an essay by Singhvi and General Catalyst’s KV Mohan. Under the model, the firm pre-funds a company’s sales and marketing budget. In return, General Catalyst is entitled only to the customer value created by that spending, and its entitlement is capped at a fixed amount; once the firm reaches that amount, the remaining lifetime value of those customers stays with the company.
If the sales and marketing spend does not perform as expected, the firm says it owns the downside: General Catalyst gets paid only if and when the company gets paid, and the company never comes out of pocket to repay it. The firm argues the structure fits sales and marketing spending because payback is variable, unlike debt that must be repaid or refinanced on a fixed schedule, and it presents the fund as an alternative to financing customer acquisition with dilutive growth equity. On its capital page, General Catalyst pitches the fund to companies acquiring new customers after product-market fit without relying solely on equity or debt.
Reported Scale and 2025 Milestones
In a December 22, 2025 release, Otter said it had crossed $100 million in annual recurring revenue in March 2025 with a team of fewer than 200 employees, generating more than $500,000 in revenue per employee. At that time, the company reported more than 35 million users and over $1 billion in customer ROI.
Otter launched a suite of voice AI meeting agents in March 2025, which the company describes as a Meeting Agent that participates in meetings to answer questions and complete tasks in real time, a Sales Agent that coaches sales representatives during customer calls, and an SDR Agent that conducts live product demos with prospects on its own. In October 2025, Otter launched an enterprise suite with a public API for custom integrations with platforms such as Jira, HubSpot, and Salesforce, a Model Context Protocol (MCP) server connecting Otter data to external AI models including Claude, advanced admin controls, and a desktop app for bot-free recording. The company achieved HIPAA compliance in July 2025 alongside its existing SOC 2 Type II certification, and it expanded language support during the year to include French, Spanish, and Japanese.
Prior Funding
Otter’s earlier institutional backing includes a $50 million Series B announced on February 25, 2021, led by Spectrum Equity with participation from Horizons Ventures, Draper Associates, GGV Capital, and Draper Dragon Fund. That round included a $10 million convertible note, and Spectrum Equity managing director John Connolly joined Otter.ai’s board of directors. Otter.ai is headquartered in Mountain View, California; Liang is co-founder and CEO, and Yun Fu is co-founder and CTO.
