Rewind's searchable-memory app died after Meta bought its Limitless successor
Rewind raised $33M+ to make everything you saw searchable, pivoted to a $99 AI pendant (Limitless), then Meta acquired it and wound the original app down.
Rewind · Limitless
What the business is
Personal-AI company: first a Mac app that recorded screen and audio into a searchable private memory, then Limitless, an AI meeting recorder plus a $99 conversation-recording pendant.
Starting capital：$33M+ from a16z, First Round Capital and NEA, including a $10M a16z round in 2022; an unusual Series A raised publicly via an X pitch video was reportedly left unspent.
How it started
Dan Siroker (ex-Google, founder and former CEO of Optimizely) and Brett Bejcek started Rewind around 2020 on the bet that everything you see, say, or hear should be searchable. The Mac app recorded screen and audio locally, and a16z backed it with $10M in 2022; a later 'unusual' Series A, raised by posting a pitch video on X, reportedly went unused.
What happened
In April 2024, with generative AI making searchable memory more useful but competition bigger, the company rebranded to Limitless: an AI meeting suite plus a $99 pendant, which pulled 10,000+ preorders. It stopped actively building the Rewind app, dropped the promised Windows version, and bet that a wearable could own the memory category before larger AI players did.
How it ended up
By late 2025 that bet had lost: bigger players were shipping their own AI wearables, and on Dec 5, 2025 Meta acquired Limitless for undisclosed terms. Hardware sales stopped immediately, subscription fees were waived, and the Rewind app — the original product — was wound down, with data export or deletion offered.
Background
Rewind was founded around 2020 by Dan Siroker (ex-Google, founder and former CEO of Optimizely) and Brett Bejcek on the bet that everything you see, say, or hear should be searchable. Its Mac app recorded screen and audio locally — a private, searchable memory — and a16z backed it with $10M in 2022. A later 'unusual' Series A, raised by posting a pitch video on X, reportedly went unused.
In April 2024, with generative AI making the idea more useful but the field more crowded, the company rebranded to Limitless: an AI meeting recorder plus a $99 conversation-recording pendant, which drew 10,000+ preorders. It stopped building the Rewind app, dropped the promised Windows version, and bet that a wearable could own the memory category before OpenAI and Meta did.
By 2025 that bet had lost. Larger AI players were shipping their own wearables, and on Dec 5, 2025 Meta acquired Limitless for undisclosed terms. Hardware sales stopped immediately, subscription fees were waived, and the Rewind app — the original product — was wound down, with data export or deletion offered. The team joined Meta's Reality Labs wearables organization.
What has to be true
- The product was genuinely novel — a searchable record of your screen and audio — but privacy, storage, and performance costs kept it a tool for power users rather than a mass product.
- ChatGPT both validated the idea and raised the bar: the same wave created better-funded competitors chasing the same memory data.
- The pivot to a $99 pendant was a second bet on AI wearables, where OpenAI and Meta were entering with far larger resources and no startup had yet won.
- Fundraising on story (a public X pitch, with Series A money reportedly unspent) bought time but not a moat; when Meta moved into wearables, an exit on undisclosed terms was the best ending.
What can be applied
A compelling demo is not a market: searchable memory stayed a niche, and each pivot (app → pendant) re-gambled on a category where OpenAI and Meta had better distribution and deeper pockets.
Aftermath
As of Aug 2026, Limitless' team works inside Meta's Reality Labs wearables organization; financial terms were never disclosed. The $99 pendant is no longer sold, subscription fees were waived, and the original Rewind app was wound down, with data export or deletion offered to users. The company had raised $33M+ across a16z, First Round and NEA, and its arc — memory app to AI pendant to Meta — became a reference point for AI-hardware consolidation.
