Ex-Plaud Exec Raises $26M for Ambi's Always-Listening AI App

Ambi, a startup founded by former Plaud executive Peter Mo, has raised $26 million across multiple funding rounds to build an AI app that listens to people throughout the day and surfaces suggestions in real time, according to a TechCrunch report. The company announced the raise on Monday and is simultaneously releasing apps for iPhone, Mac, and Apple Watch.

What is Ambi and who founded it?

Ambi is built by Peter Mo, who previously worked at Plaud, a company known for AI hardware that records and transcribes conversations. Mo is Ambi's co-founder and CEO, according to TechCrunch. His pitch for Ambi is that intelligence should not be confined to a screen or delayed by upload times. "The way we interact with intelligence is limited. Often the intelligence is trapped on the screen, and if you use hardware like Plaud, you need to wait for recording to transfer to the phone, upload to the cloud, and get intelligence after processing. That's why we are building Ambi to use AI anytime and anywhere," Mo told TechCrunch.

How much funding did Ambi raise, and from whom?

The company has raised $26 million across multiple rounds, led by Luminous Ventures, TechCrunch reported. Luminous Ventures has previously backed Meituan and Unitree Robotics. The round also included original design manufacturer Huaqin, a backer that could matter if Ambi moves forward with its own hardware.

How does Ambi's always-listening AI work?

Ambi functions like a meeting notetaker at its core, but users can opt to leave it listening throughout the day to capture broader context, according to TechCrunch's reporting. During meetings, the app's agent is designed to proactively surface suggestions or relevant knowledge pulled from a user's calendar, prior meetings, personal knowledge base, and web data — working while the conversation happens rather than only summarizing it afterward. Users can also start a task on one device and pick it up on another.

Ambi's upcoming desktop app is intended to go further, observing the work users do on their machines and storing key details in memory to generate more personalized suggestions, TechCrunch reported. The outlet noted that apps like Littlebird and Minimi already attempt similar persistent-memory features. Mo's company is also planning a standalone hardware device with a screen, speaker, camera, and microphones built specifically to capture context and display information back to the user.

Why are privacy advocates concerned about always-on AI apps?

TechCrunch framed Ambi's launch against a backdrop of "growing concerns around AI devices that don't have enough indicators to suggest they are" recording — a worry that applies broadly to apps and gadgets designed to listen, watch, or log activity continuously. The report noted that any tool collecting data about a person on an ongoing basis carries inherent privacy and data-security risk, even as startups building in this space are operating on the belief that the market for personalized assistance is large enough to outweigh those concerns.

Ambi is entering a category where multiple companies are betting that more persistent data collection produces better AI assistance, a trade-off that remains unresolved industry-wide. Meta's release of its first frontier AI model this week is a separate example of major players racing to build more capable, context-hungry AI systems, HTT News reported.

How is Ambi different from Plaud's hardware?

Mo's prior company, Plaud, built standalone recording hardware that required a separate transfer-and-upload step before users could get AI-generated insights, according to his comments to TechCrunch. Ambi's software-first approach — running on phones, laptops, and watches a person already carries — is designed to remove that lag by processing context closer to real time. The planned Ambi hardware device, with its own screen, speaker, camera, and microphones, would eventually give the company a Plaud-style physical product again, but one built to work in tandem with the software rather than as a standalone recorder waiting for a sync.

For now, Ambi's near-term bet is on mobile and desktop apps that ask people to decide how much of their day they want an AI system listening to, a decision TechCrunch's reporting suggests will remain central to how this category is judged by users and regulators alike.
