Aina builds Aina AI hardware for people who want faster ways to trigger AI actions across their laptop and phone. The Bengaluru- and San Francisco-based startup has raised $5.5 million in its first round as it chases a problem a lot of AI users now feel every day: the models keep getting better, but the ways we control them still feel clumsy. Founded in 2025 by former Ultrahuman hardware executive Apoorv Shankar, the company is starting with a tiny keypad called Dune and using it as a live test for a much bigger bet on AI interfaces.
Shankar’s pitch is pretty direct. He isn’t trying to build another gadget that just listens, records, and summarizes your life. He wants hardware that helps you do things — join a call, mute yourself, run a script, trigger an agent, approve a pull request, or fire off a workflow without hunting through tabs and shortcuts.
What is Aina AI hardware and how does Dune work?
Dune is a 3-key, context-aware macOS keypad that plugs in over USB-C and changes what each button does based on the app you’re using. If you’re in a meeting, it can surface the right call controls. If you’re in a developer tool, it can swap to coding actions and if you’re in Notion, Figma, or Excel, it can trigger common shortcuts without making you remember them. That’s the core of Aina AI hardware right now: fewer menus, fewer keyboard gymnastics. More one-tap actions.
The meeting workflow is more specific than the source article suggested. Dune syncs with your calendar and surfaces a meeting link 2 minutes before a call. One key joins the meeting. Another can send a “running late” email. Once the meeting starts, the keys can become physical mic and camera toggles. One press can also pull the meeting window to the front if it’s buried under tabs.
For developers and heavy desktop users, Dune is basically a programmable control surface that keeps remapping itself. The device detects whether you’re in GitHub, VS Code, Claude, or another supported app and updates the keys in real time. Users can open URLs and run scripts. They can also install workflows from a Dune marketplace. Users can even configure the setup through a chat interface with Claude instead of digging through settings. It ships as a CNC-machined anodized aluminum accessory, weighs 50g, and runs without a battery.
That matters because most macro pads still assume the user will do the hard part. You program them. You remember the layers and you remember the shortcuts. Dune is trying to remove that setup tax.
Who founded Aina and why did Apoorv Shankar start it?
The founding story
Aina — “mirror” in Hindi — was incorporated in May 2025 and spent its first stretch in stealth under the name Project Mirage. The company has been operating like an HCI lab, testing different forms of AI-native hardware before deciding what deserves a real launch. That’s how it ended up with 3 experimental products instead of just 1.
Shankar has been blunt about why he left Ultrahuman. “I left Ultrahuman last year because I was just super curious about the space of AI interfaces,” he said. “Devices like Rabbit and Humane Pin had launched, and I had my own disappointments with them.” He liked the idea of new interfaces. He just didn’t like the first batch enough to stop there.
Why Shankar looks credible here
This isn’t a software founder dabbling in hardware for fun. Shankar is an engineer-turned-product designer who spent years building consumer devices, and he was previously VP of Hardware at Ultrahuman. Before that, he completed an MDes at the Indian Institute of Science and built products through LazyCo, a startup focused on interface hardware. His own posts show he spent 3.5 years at Ultrahuman working on hard manufacturing problems, including scaling production of the Ring Air.
That background matters more than the buzzwords. Small hardware is unforgiving. So are supply chains. A founder who has already shipped miniaturized devices has a much better shot than someone still treating prototypes like product-market fit.
Past ventures and execution record
LazyCo is the clearest proof point. The startup built the Aina Ring, a wearable that let users control smartphone actions from a ring, and its Kickstarter campaign brought in more than $36,000. LazyCo was founded in 2017, and Ultrahuman later acquired it — which is how Shankar moved in-house before eventually heading back out on his own.
There’s a clear through-line here. Years ago, he was already trying to reduce touchscreen friction with a ring. Now he’s revisiting the same instinct in the age of agents.
Product signals, funding, and where Aina sits in the crowd
Aina has already built 3 devices: Dune, Radiance, and Shift. Radiance is a tabletop video-call remote with a volume dial plus buttons for mic, camera, AI notetaking, voice modulation, and joining meetings. Shift is a single-tap “agentic” button that connects to a phone and kicks off repeated tasks. Early testing showed Dune was the breakout, so Aina decided to ship that first and fold lessons from the others into later devices. A small group of users will begin testing the next product in the coming weeks.
Redstart Labs and 360 ONE led the funding round, with participation from MIXI Global Investments, Antler, and Blume Founders Fund. Angel backers include newly appointed WhatsApp head Kunal Shah, Razorpay co-founders Harshil Mathur and Shashank Kumar, and Scribd founder Tikhon Bernstam. The amount is $5.5 million. For a hardware startup still early in market formation, it’s a meaningful first pool of capital.
Competition is crowded, but not all of it is direct. Plaud is pushing AI note-taking devices and has sold more than 1.5 million units. Rabbit’s R1 went the handheld route at $199. Humane’s AI Pin tried to replace the phone and then collapsed fast enough that HP bought most of its assets for $116 million in February 2025 and shut the product down. Meta Ray-Bans, Bee, Friend, and smart-glasses startups all sit somewhere in the same messy category. Aina’s distinction is simpler: it isn’t betting that people want yet another passive recorder on their body. It’s betting they want fast, intentional controls for agents and workflows.
Why does Aina AI hardware’s $5.5M round matter?
This round gives Aina room to do something a lot of AI hardware companies never get to do properly: test behavior before locking the form factor.
Dune isn’t being sold as the final answer. It’s a probe. A live experiment. The company wants to learn which actions users actually repeat often enough to deserve a dedicated control surface, and which ones sound clever in a demo but don’t survive daily use. That’s a much healthier posture than launching a grand “phone killer” and hoping the internet fills in the gaps.
The investor thesis comes through here too. Backers aren’t just funding another gadget. They’re funding a founder with a manufacturing record, a clear skepticism about passive AI wearables, and a product direction that matches how AI is getting used right now — inside work, across apps, in quick bursts, with a lot of repetitive prompts and approvals.
What market is Aina AI hardware targeting?
The broad category is wearable and interface hardware for AI, and it’s getting big fast. Grand View Research estimates the global wearable AI market was worth $43.6 billion in 2025 and projects it will reach $310.6 billion by 2033, a 27.8% CAGR. On-device AI accounted for 59.1% of the market in 2025. That helps explain why founders keep trying new formats even after some very public flops.
But the more interesting shift isn’t just “wearable AI.” It’s the move from asking AI questions to assigning AI tasks. As developers and knowledge workers spend more time in Claude Code, OpenAI Codex, and meeting assistants, the friction moves from intelligence to control. This week’s custom Codex keypad from OpenAI and Work Louder fits that same pattern. So do reports that OpenAI is exploring a smart speaker, Rabbit’s agent-focused pitch, and Qualcomm’s claim that it’s experimenting with more than 40 AI interaction devices. The category is still undecided.
Conclusion: Aina AI hardware has a narrower, smarter bet
A lot of AI gadgets have tried to replace the phone. That’s usually where the pitch starts going off the rails.
Aina is taking a narrower bet with Aina AI hardware: don’t replace the computer, don’t record everything, just make high-frequency AI actions easier to trigger. That’s a more grounded idea. The next thing to watch is whether Dune’s real-world usage teaches Aina that people want a desk accessory, a portable button, or something stranger that only makes sense once agents become normal.
