On December 5, 2025, Meta announced the acquisition of AI wearable startup Limitless. Limitless is known for its pendant-style AI device that records, transcribes, and summarizes conversations. The company previously operated under the name “Rewind AI”1.
Concurrent with the acquisition announcement, the company immediately ceased sales of the $99 Pendant. Existing users will receive one year of continued support and subscription fee waivers (free migration to the Unlimited plan)2. A Meta spokesperson commented, “We’re excited that Limitless will be joining Meta to help accelerate our work to build AI-enabled wearables.” The acquisition price was not disclosed, but the company had previously raised over $33 million from Sam Altman, Andreessen Horowitz (a16z), First Round Capital, and NEA1.
Background and Meta’s Strategy
In its announcement, Limitless stated that it “shares Meta’s vision of bringing personal superintelligence to everyone”1. The team will join Meta Reality Labs’ wearables division to work on products like Ray-Ban smart glasses.
CEO Mark Zuckerberg outlined his vision to “bring superintelligence to everyone” in a July 2025 open letter. This acquisition is part of that strategy. If Limitless’s conversation recording and transcription technology is integrated into Ray-Ban Meta glasses, it could enable “recall” functionality that current smart glasses lack3.
Acqui-hire Characteristics
This acquisition has strong characteristics of an “acqui-hire,” focused on acquiring talent and technology rather than continuing the product. Founder Dan Siroker is a serial entrepreneur known as a former Product Manager for Google Chrome and AdWords, Analytics Director for Obama’s presidential campaign, and founder of A/B testing platform Optimizely. The Limitless team includes many alumni from top tech companies including Apple, Google, Meta, Amazon, and SpaceX, and this talent will now join Meta Reality Labs.
Impact on Existing Users
Service Continuity and Discontinuation
| Item | Change |
|---|---|
| Hardware sales | Ended immediately |
| Existing Pendant support | Continues for one year |
| Subscription | Free migration to Unlimited plan |
| Rewind app (Mac) | Discontinued |
| Minimum age | Lowered from 18 to 13 |
Expanded Regional Restrictions
Following the acquisition, users in the EU, UK, Brazil, Israel, South Korea, Turkey, and China lost access to the service. Users in these regions were notified to export their data by December 19, 20252. Compliance with data protection regulations such as GDPR appears to be the reason.
Privacy Concerns
The most notable aspect of this acquisition is the change in privacy protections. Limitless Pendant previously offered HIPAA-compliant medical-grade privacy protection, but this protection is lost under Meta ownership4. Healthcare professionals and therapists who used the device for clinical purposes will need to migrate to alternative platforms.
On Reddit, a post stating “I’m looking at this pendant on my desk like it’s a wiretap” went viral, revealing deep-seated distrust of Meta’s data collection practices4. Competing platform Omi reported that “most Limitless users migrated to Omi,” as users seeking HIPAA compliance and local data storage options search for alternative services.
Impact on the AI Wearables Industry
Meta’s acquisition of Limitless demonstrates the growing presence of major tech companies in the AI wearables market. In July 2025, Amazon also acquired similar AI wearable startup Bee (a $49 wristband device), indicating that major players are consolidating the market4.
Akshay Narisetti, founder of Pocket, noted that “the big platforms are waking up to the fact that the next interface won’t be a screen.” Meanwhile, independent startup founders express concern about intensifying competition with tech giants, even as market legitimacy is established.
This acquisition may cause the AI wearables market to diverge in two directions: “big tech-led” and “privacy-focused independents.” How Meta integrates Limitless’s technology into its own products, and how existing user data is handled, will be important indicators of the AI wearables market’s future direction.
