The race to define the next generation of human-computer interaction is no longer confined to the screens of our smartphones or the browsers on our laptops. A new, crowded landscape of startups is vying to determine how humans will command the rapidly evolving world of artificial intelligence. From smart rings and AI-integrated pins to specialized keypads, the quest to build the perfect "AI interface" has become the primary obsession of Silicon Valley and the burgeoning tech ecosystem in India.
The latest entrant to this high-stakes arena is Aina (Hindi for "mirror"), a startup co-founded by hardware veteran Apoorv Shankar. Headquartered across Bengaluru and San Francisco, the company has officially announced a $5.5 million funding round, signaling a robust investor appetite for hardware that promises to bridge the gap between human intent and machine execution.
The Funding Milestone: Backing the "Agentic" Future
Aina’s $5.5 million Series A round was led by Redstart Labs (a subsidiary of Info Edge India) and 360 ONE. The round also saw participation from key institutional players, including MIXI Global Investments, Antler, and the Blume Founders Fund.
Beyond institutional capital, the round attracted significant attention from influential figures in the tech industry. Notable individual investors include Kunal Shah, the head of WhatsApp; Harshil Mathur and Shashank Kumar, the co-founders of the payments giant Razorpay; and Tikhon Bernstam, the founder of Scribd. This roster of backers underscores a shared belief that the current "touch-and-type" paradigm of computing is ripe for disruption as AI agents become more autonomous.
A Chronology of Hardware Evolution: From Ultrahuman to Aina
The genesis of Aina—formerly known as "Project Mirage"—is deeply rooted in the experience of its founder, Apoorv Shankar. His journey into the hardware space is a testament to the rapid iteration cycle of modern product design.
The Foundation
Before launching Aina, Shankar served as the VP of Hardware at the Bengaluru-based smart ring pioneer, Ultrahuman. His path to that role was paved by his previous venture, LazyCo, a startup that focused on simplifying hardware interfaces. LazyCo made headlines for developing a ring that allowed users to control external devices, such as smartphones, through simple gestures. When Ultrahuman acquired LazyCo, Shankar was brought in-house to scale those concepts.
The Turning Point
Despite the success of the smart ring category, Shankar found himself increasingly preoccupied with the broader, more chaotic evolution of AI. He observed the high-profile launches of devices like the Rabbit R1 and the Humane AI Pin—two products that promised to liberate users from screens but largely faced criticism for their lack of utility and clunky execution.
"I left Ultrahuman last year because I was just super curious about the space of AI interfaces," Shankar explained in an interview. "Devices like Rabbit and Humane Pin had launched, and I had my own disappointments with them. However, I was just excited that we are seeing interfaces being a thing now. And as an engineer turned product designer, this was the hottest thing I could imagine myself building."
The Product Strategy: "Dune" and the Shift Toward Action
Aina’s product philosophy is not rooted in the passive "always-listening" devices that currently dominate the market. Instead, the company is prioritizing agency.
The Dune Keypad
The company’s flagship product, Dune, is a three-key, context-aware "macro" keypad. Unlike complex hardware, Dune is elegantly simple. It acts as a bridge between the user and their software environment, allowing for granular control over meeting microphones, camera toggles, and, most importantly, the execution of custom scripts based on the specific application the user is currently navigating.
Iteration Through Discovery
Aina initially prototyped three distinct devices:
- Dune: The three-key macro controller.
- Radiance: A tabletop remote designed specifically for video conferencing, featuring a volume dial and dedicated buttons for AI-driven notetaking and voice modulation.
- Shift: A single-tap "agentic" button designed to trigger complex, repetitive AI workflows on a connected smartphone.
In early testing, the company discovered that Dune resonated most strongly with power users. Aina realized that the core functionality of Radiance and Shift could eventually be folded into the Dune form factor, leading them to prioritize its launch. By shipping Dune first, Aina aims to gather real-world telemetry on how users interact with their machines, using that data to refine their vision for future "agentic" hardware.
The Competitive Landscape: A Crowded Field
Aina enters a market where there is no consensus on what the "winning" form factor should be. The landscape is currently fragmented into several distinct schools of thought:
- The Wearables: Companies like Bee and Friend are banking on the idea that AI should be a constant companion, tethered to the body.
- The Smart Glasses: Meta’s Ray-Bans and the unicorn-valued Even Realities are betting that the future of AI is optical—overlaying digital information onto the physical world.
- The "Puck" and "Pin" Brigade: Startups like Plaud and Pocket are focusing on credit-card-sized or wearable devices designed to capture, transcribe, and summarize real-world interactions.
This fragmentation is largely because the industry is still grappling with a fundamental question: How do we control an AI that is smarter than the device it runs on? As the industry shifts from simple chatbots to autonomous agents, the need for physical triggers—buttons, dials, and tactile inputs—has grown. OpenAI’s recent collaboration with Work Louder on a custom keypad for its Codex model is a prime example of this trend. Even tech giants like Qualcomm are reportedly experimenting with over 40 different device form factors to find the right way to facilitate human-AI communication.
Implications: The Death of the "Passive" AI Gadget
Aina’s strategy points to a significant pivot in the industry. For the last two years, the focus has been on "context capture"—gadgets that record meetings, listen to conversations, and transcribe thoughts. While useful, these devices often fall into the trap of creating a "digital clutter" of transcripts that users never revisit.
Shankar believes the future is not about capturing more data, but about triggering more action. "I think you have enough context in your phone and your laptop all the time, and we haven’t even started using that well," he said. "We are building an action-oriented device that will use the context to help you control and trigger workflows."
The "Agentic" Shift
The industry is moving toward "Agentic AI," where LLMs don’t just provide answers but perform tasks—such as booking flights, writing code, or managing calendars. Aina’s bet is that the keyboard, even in a minimized, macro-keypad form, remains the most efficient way to signal intent to these agents. By providing a tactile "trigger" for an AI agent, Aina hopes to move beyond the novelty of AI wearables and into the realm of professional productivity.
Future Outlook: Building the "Mirror"
Aina is currently keeping the details of its next major device under wraps. However, the company has confirmed plans to initiate a closed beta testing phase with a select group of users in the coming weeks.
The name "Aina" suggests a vision that is reflective—a mirror for the user’s intentions. As the startup prepares for its next phase of growth, it faces the formidable challenge of proving that a hardware interface can be more than a temporary bridge to a world where voice or neural interfaces might eventually take over.
For now, the battle is being fought on the desk, in the palm of the hand, and on the lapel. Whether it is through a three-key keypad or a future device yet to be unveiled, Aina is positioning itself as a vital component in the workflow of the modern, AI-augmented knowledge worker. In a world of infinite software possibilities, the startup is betting that the most powerful thing an AI can have is a physical button to push.
