Former Plaud Exec's Mistlabs Raises $26M for Ambient AI App Ambi

On Monday, Oct. 12, 2026, San Francisco-based Mistlabs announced $26 million in funding and the full launch of Ambi, an AI app for Apple devices that can listen in the background, build a memory of its user and act on what it hears. The company's CEO and co-founder, Peter Mo, is a former executive at Plaud, the maker of AI voice recorders.

What happened

According to the company's announcement, Mistlabs raised $26 million in what it calls Pre-A funding, led by Luminous Ventures and Huaqin Technology, a device manufacturer. TechCrunch reported that the money came across multiple rounds and noted that Luminous Ventures has backed companies such as Meituan and Unitree Robotics.

Ambi is now out of beta on iPhone, Apple Watch and Mac. At its simplest, it works like a meeting note-taker. Users can also choose to let it listen throughout the day so it can capture context from conversations. From there, the app's AI agent can offer suggestions or surface useful information during meetings, drawing on the user's calendar, past meetings, a knowledge base and the web. A task started on one device can be finished on another.

The company says Ambi builds a memory of each user and reasons across devices in real time. A feature called Routine uses several AI agents together, for example to fact-check a meeting while it is happening.

Mistlabs also shared plans for what comes next:

• Agent-to-agent communication is expected in the coming months, including AI agents that negotiate on a user's behalf during meetings, within permissions the user grants.
• A desktop app that observes a user's work and stores the important parts in memory, according to TechCrunch.
• A hardware device, which TechCrunch says will have a screen, speaker, camera and microphones. The company says its AI wearable will follow later this year.

On privacy, TechCrunch reported that ambient capture is off by default and can be turned off at any time. Mistlabs says it does not store audio by default and that it encrypts data, though it did not say which encryption method it uses. Mo told TechCrunch that the responsibility for telling others they are being recorded falls on users, and he acknowledged, "We, as an industry, haven't solved this problem."

In the press release, Mo said, "We're moving beyond AI that simply waits for a prompt." TechCrunch reported the company has more than 50 employees across San Francisco, Beijing, Shanghai and Shenzhen.

Why it matters

Most AI assistants still wait for you to type or speak a request. Ambi is part of a growing group of products that try to work the other way around: they gather context first, then step in with help before you ask. That idea, often called ambient AI, is one of the clearest trends in consumer AI this year.

It also raises real questions. An app that listens all day has to earn a high level of trust, and recording laws vary by state and country. How Mistlabs handles consent and data security will matter as much as how smart the app is.

The funding shows that investors still see room for new consumer AI apps, even with large tech companies building assistants of their own.

What this means for founders and builders

Ambi's launch highlights two things every product builder should think about now.

The first is memory. Apps that remember their users feel more useful over time, and that makes people less likely to switch. If you are designing a product, ask what it should remember about each customer and how that memory makes the next visit better.

The second is trust. Any product that touches personal data, especially audio, needs clear privacy settings, simple controls and plain-language explanations. Building those in from day one is far easier than adding them after a complaint.

The bottom line

Mistlabs has $26 million and a live product to prove that AI that listens, remembers and acts on its own is something people want. Whether Ambi wins will depend on usefulness and trust in equal measure, and that is a lesson for any team building the next generation of AI apps.
