From Passive Recording to Active Control

Most AI wearables on the market today — from the Humane AI Pin to the Rewind Pendant — share a common premise: record everything around you and let AI make sense of it later. Apoorv Shankar, former VP of Hardware at Ultrahuman, thinks that's the wrong framing entirely.

Shankar's new startup, Aina, has raised $5.5 million in early funding to build a new category of device — one designed to control AI agents, not merely capture input for them. A pilot of the first Aina device is expected in the coming weeks.

What Aina Is Actually Building

The core distinction Aina is drawing is between ambient recording and agentic orchestration. Passive devices listen and transcribe; Aina's hardware is being designed to serve as an interface layer between the user and a network of AI agents capable of taking actions in the world.

This positions the device closer to a physical controller for AI workflows than a glorified voice memo app. Think less "wearable microphone" and more "AI remote control you wear."

While technical specifications for the pilot device haven't been fully disclosed, the framing suggests Aina is betting that:

  • Agentic AI — systems that browse, book, message, and execute tasks autonomously — will become a primary computing interface
  • Users will want dedicated hardware to manage and direct these agents reliably
  • Existing form factors (phones, earbuds, pendants) aren't purpose-built for this interaction model

Why Shankar Is the Right Bet Here

Shankar's background at Ultrahuman — the Bangalore-based health wearables company known for the Ring AIR — gives him direct experience shipping consumer hardware at scale. That's a non-trivial credential in a space littered with AI hardware startups that never got product to market.

The $5.5M raise is modest by Series A standards but appropriate for a hardware company still in pilot phase. Getting the device into real users' hands before raising a larger round is a disciplined sequencing choice — especially given how badly the Humane AI Pin's rushed launch damaged that company's trajectory.

The Broader Market Context

The AI hardware space is in a strange moment. Humane sold to HP's Poly division after its AI Pin flopped commercially. Rabbit has struggled to find product-market fit with the R1. Meanwhile, Meta's Ray-Ban smart glasses have quietly become the most successful AI wearable on the market — largely by not overreaching.

What's changed since those early stumbles is the underlying capability of AI agents. Twelve months ago, "agentic AI" was mostly a roadmap promise. Today, with OpenAI's Operator, Anthropic's Claude handling multi-step tasks, and Google's Project Mariner browsing the web autonomously, the infrastructure for an agent-control device actually exists.

That timing shift is arguably what makes Aina's pitch more credible now than it would have been in 2024.

What This Means for Founders and Builders

For startup founders watching this space, Aina's raise signals a few things worth tracking:

  • Hardware-as-agent-interface is becoming a legitimate product category, not just a pitch deck concept
  • The "control layer" framing — positioning a device as an orchestrator rather than a recorder — could differentiate future AI hardware from the failed ambient-capture wave
  • Investors are still willing to fund early hardware bets when the founder has supply chain credibility and a clear pilot plan

Aina's pilot will be the real test. Execution in hardware is unforgiving, and the gap between compelling concept and shippable product has killed more AI hardware companies than bad ideas have.
