antimattr, an India-origin YC startup, launches earbuds that hear only your voice and a ring that controls your AI agents

antimattr, a hardware startup started by two Indian founders, has formally launched project mnemosyne on Y Combinator's Launch YC page on 13 November. The product pairs earbuds built to pick up only the wearer's voice with a smart ring used to trigger and check on AI agents. YourStory, which profiled the company earlier this month, describes it as the first India-origin wearable company backed by the accelerator, which counts it in its Fall 2026 batch.

The company was started in 2025 by Sridipto Ghosh, its CEO and an IIT (BHU) graduate, and Sirsha Chakraborty, its CTO. The two had earlier built a software startup called Snipe. In an interview with Talk Orbis, Ghosh said that while building voice agents they found the models were good enough but the noise around users kept breaking the experience, which convinced them the fix had to be in hardware close to the mouth.

According to the company, the earbuds use its own voice isolation technology to filter out close to 90 decibels of background noise and cut the word error rate in transcription from about 30 percent on AirPods to under 5 percent. These are the founders' own figures and have not been independently tested. The ring is meant as a quiet input device: a tap can capture a thought, start a workflow, or record and summarise a conversation into a searchable memory.

The founders say they met nearly 150 manufacturers in China in April before finding partners, that their first batch shipped in June and sold out, and that they now have more than 2,000 pre-orders. They moved to the United States in July and the company is now based in San Francisco, with part of its small team in India. YourStory reports that it is backed by YC and WTFund, and that it got off the ground at Scaler Innovation Lab, which gave it access to 3D printers and soldering stations.
