Consumer hardware startup Aina has raised $5.5 million in seed funding to develop a new form factor for interacting with AI agents. The round was led by Redstart Labs — an early-stage fund backed by Info Edge — and 360 ONE Asset, with participation from MIXI Global Investments, Antler, Blume Founders Fund, and individual backers including Kunal Shah, Tikhon Bernstam, Razorpay co-founders Harshil Mathur and Shashank Kumar, and Vaibhav Domkundwar.

Founded by Apoorv Shankar, a former VP of hardware at smart-ring company Ultrahuman, Aina is building what it describes as a general-purpose interface for AI agents. The startup operates across Bengaluru and San Francisco and is betting that the next shift in computing requires dedicated hardware — not another app on a phone designed primarily for browsing.

Aina’s thesis is straightforward: as AI assistants grow better at understanding context and executing multi-step tasks, the user’s role shifts from operator to approver. “All we will have to do is say yes or no,” Shankar said in a statement. The device would use information already available on a person’s phone or computer to surface and trigger digital workflows, reducing the repetitive manual navigation that current interfaces demand.

While the flagship product remains undisclosed, Aina has already shipped its first release: Dune, a compact three-key keypad for Mac that changes its assigned functions based on the active application — controlling mics and cameras during calls or running shortcuts and scripts.

The company showed three experimental interfaces at CES earlier this year; Dune drew the strongest response and has since been placed with hundreds of early adopters whose feedback is shaping the main product. A waitlist is open for a pilot programme, though no commercial launch date has been set.

For buyers and partners outside India, Aina represents a corridor play — hardware R&D rooted in Bengaluru’s deep consumer-electronics talent pool, with go-to-market pathing through San Francisco.

As global technology firms and startups race to land on the dominant form factor for agentic AI — wearables, glasses, pins, desktop peripherals — Aina is placing an early bet that a low-friction approval device, not a full-screen interface, wins the workflow. Backing from a mix of Indian institutional capital and global early-stage funds signals conviction that the answer may not come from a Silicon Valley giant alone.
