- Otter.ai has secured $320M in repayable financing from General Catalyst’s Customer Value Fund.
- The deal is non-equity: Otter repays it with interest, so shareholders are not diluted.
- Otter has 40M+ users but has not disclosed the enterprise revenue it is betting on.
Most of what gets said in meetings is never seen again. Otter.ai wants to catch it. The Mountain View-based AI notetaker has closed $320 million in growth financing from General Catalyst’s Customer Value Fund, and plans to use it to sell that idea to big companies.
This is not an equity round. CEO Sam Liang told Reuters the money is repayable with interest, and that Otter’s shareholders are not diluted. The fund pays for sales and marketing and earns its return from the results of that spend, and Liang said it could provide more capital once the first amount is used. The repayment terms have not been made public.
“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, co-founder and CEO of Otter.ai.
A repayable vision on enterprise sales
Otter will spend the money on enterprise growth, go-to-market strategy, international expansion and product development. Liang said it plans to double or triple its sales and marketing budget, grow a small sales team, and market harder outside the US. The US is its biggest market, followed by Canada, Britain and India.
The startup, founded in 2016 by Liang, a former Google engineer, and Yun Fu, joins Zoom, Microsoft Teams, and Google Meet calls, transcribes speech in real time, identifies speakers, and produces summaries and action items. In July, it launched Live Assist, an Enterprise agent that coaches users during a live call. Sales teams are its main early adopters.
Otter says it has more than 40 million users, up from 25 million a year ago, with teams at over 86% of the Fortune 500. It reports more than 1 billion meetings transcribed, a milestone it first announced in February 2023. It also claims more than $1.5 billion in customer return on investment from time saved.
Otter passed $100 million in annual recurring revenue in March 2025. Its earlier backers include Spectrum Equity, Horizons Ventures, and Draper Associates, and its last equity round was a $50 million Series B in 2021.
Why General Catalyst is backing voice AI
The CVF is becoming a habit for General Catalyst. In September, Motive took more than $1.3 billion from the same fund and withdrew its IPO filing, as Tech Funding News reported. The fund also put $1 billion into Grammarly. In March, Bloomberg reported that General Catalyst was in early talks to raise about $10 billion in new funds.
“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 at General Catalyst.
He added that when companies capture voice data and turn it into business insights, teams move faster and make better decisions, which is why he sees Otter as a strong CVF partner.
Competition in the AI meeting intelligence space
Otter’s rivals have raised money very differently.
London-based Granola raised a $125 million Series C at a $1.5 billion valuation in March, led by Index Ventures, with Kleiner Perkins also investing. That valuation was up from $250 million less than a year earlier. Fireflies.ai hit $1 billion through a tender offer in June 2025. It says it has been profitable since 2023 and has raised no primary capital since 2021. Built-in assistants from large software providers add to the pressure.
The AI meeting assistant market is projected to grow from about $3.5 billion in 2025 to more than $34 billion by 2035, according to Market Research Future.
Trust is the other test. A federal class action filed in August 2025 alleges that Otter’s notetaker can join meetings and record people without every participant’s consent, and that it used recordings for AI training. Otter has built its distribution on a notetaker that joins the call, so that is the exact feature under challenge.
The financing only works if sales spend turns into revenue Otter can measure and repay. If it does, Otter keeps its equity and a bigger enterprise business. If it doesn’t, it owes General Catalyst anyway while Granola and Fireflies compete on products.
The open question is whether companies will treat a meeting transcript as their record of what was said, or leave it as a feature inside the video call.
