Pulsetto

Pulsetto was founded in 2021 in Vilnius, Lithuania.^[4] It has been described as a health-technology company developing a wearable device for non-invasive vagus nerve stimulation, marketed for uses such as stress reduction and sleep support.^[4][5] In February 2025, the company announced a €2 million investment from Scalewolf, a Lithuanian dual-use technology accelerator and venture capital fund, aimed at expanding its vagus nerve stimulation technology into defence-related applications.^[4][6]

Pulsetto manufactures a wearable device intended to deliver transcutaneous electrical stimulation to the vagus nerve through the skin of the neck. The device is controlled via a mobile application that provides preset stimulation programs categorized under stress, sleep, and relaxation-related terms.^{[7][8][9][10][11]}

Pulsetto is grounded in scientific research on the vagus nerve and its role in autonomic control, including its effects on stress response, sleep, and mood control. The product is based on transcutaneous vagus nerve stimulation (tVNS), which has been researched in various clinical and experimental settings.^[12]

As of 2025, limited independent peer-reviewed clinical studies have been published specifically evaluating Pulsetto’s device. Analysts have noted that the device reportedly operates at stimulation frequencies higher than those commonly cited in published VNS research.^[13]

Independent reviewers have raised concerns regarding the company’s use of imagery and references from broader vagus nerve stimulation research in its marketing materials. Some commentators have questioned whether the cited studies directly evaluated the Pulsetto device.^[14]

Consumer responses have been mixed, with some users reporting perceived benefits and others expressing dissatisfaction.^[15][16][17]
