Aina is going to pilot a new device in the coming weeks.

The race to build the next AI interface is crowded with startups. The Sandbar ring, Plaud’s AI pin and desktop notetaker, and Pocket’s credit card-sized pucks are all vying to capture what you say and do. Bee and Friend take the wearable route, while Meta Ray-Bans and Even Realities are betting on smart glasses. Now, a Bengaluru- and San Francisco-based startup, Aina (“mirror” in Hindi), is trying to make its own mark in this crowded field of human-computer interface devices. The company announced today that it has raised $5.5 million in a round led by Redstart Labs (Info Edge India) and 360 ONE, with participation from MIXI Global Investments, Antler, and Blume Founders Fund. The round also drew individual investors, including newly appointed WhatsApp head Kunal Shah, Razorpay co-founders Harshil Mathur and Shashank Kumar, and Scribd founder Tikhon Bernstam. Aina, previously known as Project Mirage, was founded by Apoorv Shankar, a former VP of Hardware at smart ring maker Ultrahuman. Before that, Shankar ran LazyCo, a hardware interface design startup that made gadgets, including a ring that let users control other devices like a smartphone. Ultrahuman later acquired LazyCo, bringing Shankar in-house before he eventually struck out on his own again. “I left Ultrahuman last year because I was just super curious about the space of AI interfaces,” Shankar told TechCrunch. “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 startup’s first product is Dune, a three-key, context-aware “macro” keyboard — essentially a small keypad that runs pre-set shortcuts — that can control the mic and camera in a meeting and run shortcuts or scripts based on the app users are viewing. Aina developed two other devices: Radiance, a tabletop remote for video calls with a dial for volume and buttons for mic, camera, AI notetaker, voice modulation, and joining the meeting; and Shift, a single-tap “agentic” button — press it once, and it triggers an AI agent to carry out a repeated task — that connects to your phone. But in early testing, Aina found Dune was the most popular of the three and realized it could bundle features of the other two devices into the keypad. That signal from users is why the company decided to ship Dune first. It wants to learn, in the wild, what kind of tasks users actually want to automate.
