Limbix is a prescription digital therapeutics platform that provides mental health treatment for young people.

Limbix builds virtual reality to improve mental health treatment by making it more effective, efficient, and easier to access.

Limbix was founded in 2016 by Ben Lewis and Tony Hsieh. The company is headquartered in Palo Alto, California.


Limbix launched SparkRx, the first digital therapeutic for adolescents with symptoms of depression. The SparkRx program is based on core principles of cognitive behavioral therapy with a focus on behavioral activation and is delivered to patients via smartphone.


Limbix also recently announced positive results from a clinical trial of SparkRx, which demonstrated a statistically significant reduction in depression symptoms, compared to an active control, for users who completed the program as recommended.


Limbix has quickly established itself as leaders in the VR Mental Health space by partnering with top university and hospital partners to build content for the Limbix VR platform.


Limbix is backed by Sequoia Capital, GSR Ventures, Storm Ventures, DN Capital, NextGen Venture Partners, Digital Garage, BIXINK Therapeutics, Korean Investment Partners, and others. The company raised $15M in Series A2 round on Dec 07, 2021. This brings Limbix's total funding to $31M to date.
