TwinMind, a new AI startup founded by former Google X engineers, is emerging from stealth with an ambitious vision: creating an always-listening AI assistant that rivals ChatGPT and Gemini. Led by CEO Daniel George, the company has raised over $2.5 million across two funding rounds this year, achieving a $30 million post-money valuation. Notable investors include Oracle’s chief AI scientist Dan Roth, Rocketship VC founding partner Anand Rajaraman, and Michael Liou, an early backer of Robinhood and Zapier.
The startup’s flagship product is a smartphone app that functions as a personalized AI companion, drawing comparisons to Jarvis from Marvel’s Iron Man franchise. Unlike existing AI assistants like ChatGPT or Google’s Gemini, TwinMind is designed to continuously learn about users by running in the background, capturing audio conversations, transcribing them to text, and storing this information in a comprehensive memory bank. Users can then review their day broken down into key moments or ask questions that draw upon this accumulated context.
TwinMind’s competitive advantage lies in its memory capabilities. While other AI chatbots are improving at retention, George argues they still fall short of truly understanding users’ lives and contexts. The app processes most data locally on the phone for privacy, only connecting to the cloud when necessary for enhanced AI capabilities or complex queries.
The startup is also launching a Chrome browser extension that can monitor users’ online browsing (with permission) and integrate with calendars and Gmail. This allows TwinMind to draft emails and perform tasks with full contextual awareness of the user’s life, relationships, and work. George describes it as “Grammarly, but instead of correcting grammar, it actually writes based on all the memories and context.”
Privacy and technical innovation are central concerns. George emphasizes that TwinMind only transcribes audio without capturing images, placing it in the same category as Siri or Alexa. The team has achieved a significant technical breakthrough: the app can run continuously for 12 hours in the background without draining the phone’s battery, navigating Apple’s restrictive ecosystem.
TwinMind plans a freemium model with a $20-per-month premium tier for access to more advanced large language models. The company is currently raising a $5 million seed round and has over 2,000 early testers providing feedback. The iPhone app and Chrome extension launch this week on Product Hunt, with Android and Mac versions planned for 2025.
Key Quotes
If you had your own Jarvis, why would you Google? Why would you ask ChatGPT? None of these other tools capture you. None of them understand you. They don’t understand what’s happening in your life.
CEO Daniel George explains TwinMind’s core value proposition, emphasizing how continuous contextual learning differentiates it from existing AI assistants like ChatGPT and Google’s Gemini, which lack persistent memory of users’ lives.
You just go in there and, say, write your marketing email. And it knows everything about me, who my cofounders are, what my company is, what we have done before. Imagine Grammarly, but instead of correcting grammar, it actually writes it based on all the memories and context.
George illustrates how TwinMind’s memory capabilities enable more sophisticated task completion than existing tools, positioning it as a context-aware writing assistant rather than just a grammar checker or generic chatbot.
We are sure that in a couple of years, everyone is going to have a personalized AI companion that knows their whole life and has access to all of the world’s knowledge on the internet. And that would be the way people access information. Not through Google.
George makes a bold prediction about the future of information access, suggesting that personalized AI companions will replace traditional search engines as the primary way people interact with information and technology.
The main innovation is figuring out how to get this thing running all day, in your pocket, without draining your battery, [and with] all the Apple walled garden stuff.
George highlights the technical achievement that makes TwinMind viable—solving the battery drain problem that has plagued always-on AI assistants, enabling 12 hours of continuous background operation on smartphones.
Our Take
TwinMind’s launch represents a fascinating inflection point in AI assistant evolution. While the technology is impressive, the startup faces significant challenges beyond technical execution. Consumer trust will be paramount—convincing users to allow an app to constantly listen and remember everything requires overcoming deep-seated privacy concerns, especially in an era of heightened data sensitivity.
The $30 million valuation on just $2.5 million raised suggests strong investor confidence, but TwinMind enters a brutally competitive market dominated by tech giants with vastly more resources. The real test will be whether continuous contextual learning provides enough value to overcome the “creepiness factor” and justify the $20 monthly subscription.
What’s most intriguing is TwinMind’s vision of replacing Google as the primary information access point. If successful, this could fundamentally reshape how we interact with technology, moving from active searching to passive AI companionship. However, regulatory scrutiny around AI surveillance and data collection is intensifying globally, which could significantly impact TwinMind’s trajectory.
Why This Matters
TwinMind represents a significant evolution in the AI assistant market, challenging the dominance of ChatGPT, Gemini, and traditional voice assistants with a fundamentally different approach: continuous contextual learning. This shift from on-demand chatbots to always-present AI companions signals where the industry is heading—toward deeply personalized AI that understands users’ entire lives rather than isolated queries.
The startup’s emergence from Google X, known for ambitious moonshot projects, lends credibility to its technical claims, particularly the battery optimization breakthrough that enables all-day background operation. This addresses one of the biggest barriers to ambient AI assistants.
However, TwinMind also raises critical questions about privacy, data security, and surveillance. An AI that constantly listens and remembers everything could be transformative for productivity but also presents unprecedented privacy risks. How users, regulators, and society respond to this technology will shape the future of personal AI assistants. The company’s success or failure will provide important signals about consumer appetite for trading privacy for convenience in the AI era, potentially influencing how tech giants approach their own assistant products.
