Chennai-based Neurostellar has raised angel investment of over $1,50,000 from a group, including Ather Energy’s Co-founders Swapnil Jain and Tarun Mehta. The deep-tech start-up is also raising around $1 million in another round.

Incubated at the IIT-Madras Incubation Cell, Neurostellar is developing smart brain-machine interface for tracking and decoding one’s mental fitness.

Their flagship product, Orbit, is a smart headband that combines EEG (Electroencephalography) for brain activity and PPG (Photoplethysmography) for heart rate and breathing patterns to provide real-time insights into stress, focus, and mental fatigue. However, this is not a diagnosis made with the device. Unlike wearable tech that is engaged in 24/7 tracking, Orbit is best used during key moments like deep work, meditation, or recovery to get cognitive data, co-founder Raghavendran said. “The product was used by a batch of 25 paid users in the first cohort last year, and this was also followed by a LoI for 30 devices purchased by the Indian Air Force,” he added.
