Vicarious Surgical, a Cambridge, Mass.-based healthcare robotics startup, raised another $10 million for the virtual reality-augmented robot-assisted surgery platform it’s developing, according to an SEC filing.

The latest round of funding follows on the heels of a nearly $17 million Series A round announced in April 2018. Vicarious Surgical first reported a $2.4 million raise in January 2016 and another $800,000 in October of that year.

Vicarious has said its device “combines virtual reality with proprietary human-like surgical robotics to enable surgeons to perform minimally invasive surgery through a single micro-incision,” claiming to have achieved “the goal of surgical robotics since the field’s inception – to shrink the surgeon and put them inside the patient.”

Its website lists Khosla Ventures, AME Cloud Ventures, and Innovation Endeavors as investors. Vicarious Surgical noted that six investors contributed to the current round, but did not identify them.

Vicarious came out of stealth mode in April 2018 with its Series A round. The company was founded by MIT graduates Adam Sachs and Sammy Khalifa, as well as Dr. Barry Greene, a bariatric surgeon at Advanced Weight Loss Surgery, according to LinkedIn.
