Meta snaps up AI device startup Limitless, signaling a new race for ambient AI hardware

TOP 3 STORIES:

1. Meta acquires AI device startup Limitless (fka Rewind)
Meta has acquired Limitless, the AI startup known for its wearable and desktop “second brain” that records and summarizes meetings and personal context, in a deal announced Friday.[5] For founders, this underscores big tech’s appetite for agentic, memory-centric AI products, suggesting strong exit potential for startups that turn continuous data capture into clear productivity outcomes and defensible data moats.[5]

2. Anthropic makes first acquisition, buys Bun to power Claude Code’s $1B run-rate
Anthropic has completed its first-ever acquisition, buying infrastructure startup Bun, which has been key to scaling the systems behind Claude Code, now at a $1B revenue run-rate just six months after launch.[3][9] This is a clear signal that AI infrastructure performance and developer tooling are now strategic M&A targets, so infra and devtool founders should position around reliability, latency, and cost advantages that make them indispensable to major model providers.[3][9]

3. Overjet acquires DentalBee to build end-to-end AI dental documentation platform
Dental AI leader Overjet has acquired DentalBee, a Toledo-based startup specializing in voice-powered clinical documentation, aiming to integrate imaging, diagnostics, and real-time charting into one workflow.[4] Vertical AI founders can read this as validation that specialized, workflow-native AI (voice + imaging + EHR) in regulated niches is acquisition-ready once it proves clear productivity gains and smooths reimbursement and compliance friction.[4]

Flash Insight:
The latest deals show a converging pattern: big platforms (Meta, Anthropic, Overjet) are buying narrow, high-leverage AI capabilities—memory devices, infra runtimes, and domain-specific voice tools—rather than generic models.[3][4][5][9] For founders, this favors building *deeply embedded* products with strong data loops and technical depth that can plug into larger ecosystems as “must-have modules” instead of trying to compete as standalone general AI platforms. In the near term, expect more acqui-hires and tuck-in acquisitions across AI infrastructure, vertical SaaS with AI-native workflows, and hardware that captures proprietary data, as incumbents race to lock in distribution and differentiated capabilities.[3][4][5][9]
