When Sridipto Ghosh and Sirsha Chakraborty were developing the thesis for their startup, many advised them against venturing into hardware. But this didn’t deter them.

“People said it was hard, that there were large companies in the hardware space, and that it was very difficult for a startup to build in this space. We continued building despite those perceptions,” says Ghosh.

Their persistence eventually led them to start antimattr in 2025. The deeptech company is building a voice-first hardware interface for human-agent interaction that summarises conversations with clarity even in noisy environments.

The conversations could be with anyone. Users can dictate to the wearable device directly or let it listen to a conversation with another person (offline or online). The technology would be able to pick up the conversation clearly despite ambient noise, says CEO Ghosh.

He says its early incubation at Scaler Innovation Lab helped the startup get off the ground. “It gave us access to prototyping equipment such as 3D printers and soldering stations, which made it easier to iterate and keep developing the idea."

The name ‘antimattr’ comes from the philosophy of challenging common notions or what people are generally taught. This year, the San Francisco-based startup was selected for Y Combinator’s current cohort, becoming the first India-origin wearable company backed by the accelerator.

“One of our biggest learnings so far has been that you don’t need to have everything figured out before you start. You just need to keep moving and evolving. YC has accelerated this process for us at a global stage and pushed us further in thinking about what’s possible in human-machine interaction,” says Ghosh.
