Ex-Plaud exec's always-listening AI assistant Ambi raises $26 million

Ambi, a startup founded by former Plaud executive Peter Mo, has raised $26 million across multiple funding rounds to build an AI assistant that listens to its user in the background and offers real-time help, TechCrunch reported on Monday. The rounds were led by Luminous Ventures, an investor in Meituan and Unitree Robotics, together with Huaqin, an original design manufacturer. Alongside the announcement, the company released apps for the iPhone, Mac and Apple Watch.

An assistant that listens all day

According to TechCrunch, Ambi's apps behave like meeting note-takers, but users can leave them listening throughout the day to gather broader context about their activities. The pitch rests on a common assumption in the AI industry: the more a system knows about a person, the better its suggestions can become.

Mo, who serves as co-founder and CEO, told TechCrunch that intelligence today is largely trapped on screens. With recording hardware like Plaud's devices, users must wait for audio to transfer to a phone, upload to the cloud and be processed before getting any output. Ambi, by contrast, is designed to make assistance available at any moment.

Acting during the meeting, not after it

Most meeting note-taking products summarise conversations and then automate the follow-up work through connectors into other software. Ambi wants to move that timeline up: its agent is meant to surface relevant knowledge and suggestions while a conversation is still in progress, drawing on the user's calendar, meetings, knowledge base and web data. Tasks started on one device can be picked up on another.

The company also plans to capture more context. A forthcoming desktop app will observe the work users do and store important parts of it in memory to sharpen personalisation, an approach TechCrunch compares to existing tools such as Littlebird and Minimi. Further out, Ambi intends to ship its own hardware device with a screen, a speaker, a camera and microphones to gather context and display information.

The privacy question

The launch lands amid growing unease about AI devices that give bystanders little indication that audio or video is being captured. TechCrunch notes that it is not clear whether Ambi's apps, or the planned device, will carry enough indicators to alert third parties that a conversation is being recorded if the user says nothing. Some meeting note-takers have already been sued over recording people without consent, and Apple's recently released Voice Intelligence feature, which transcribes speech continuously, has drawn similar criticism.

Ambi says ambient capture is switched off by default and can be turned off at any moment, that it does not store users' recordings, and that data is encrypted, though the company did not specify what kind of encryption it uses. Mo argued that users are instructed to inform others when ambient capture is active, but described disclosure as an unsolved, industry-wide problem that the company cannot fix if a user deliberately hides the recording.

Why it matters

The raise is a clear signal that investors remain willing to back always-on, ambient AI despite its unresolved privacy baggage. Ambi now employs more than 50 people across offices in San Francisco, Beijing, Shanghai and Shenzhen, and is hiring for go-to-market roles plus AI engineers to work on speech recognition models, suggesting it intends to build core speech technology in-house rather than depend entirely on third-party models. The underlying bet is that personalised, context-aware assistance is valuable enough for the market to absorb privacy concerns. Whether bystanders, and eventually regulators, agree is the open question every ambient AI startup now shares, and Ambi's planned camera-equipped hardware will only raise the stakes.
