Other Neurotech Companies


These startups have seen investment from NEA, Andreessen Horowitz, and DARPA, among many others.


As the digital health sector matures from basic tracking apps into highly regulated medical devices, we are seeing bleeding edge technologies being developed that blur the lines between computers and biology. And a growing share of these startups are beginning to target the brain.

The burgeoning field of neurotechnology involves brain-machine interfaces, neuroprosthetics, neurostimulation, neuromonitoring, and implantable devices intended to not only augment nervous system activity, but expand its capabilities. One such project is Elon Musk’s Neuralink, which is developing “high bandwidth brain-machine interfaces to connect humans and computers.” And even Facebook has announced plans to create brain-machine interfaces that allow users to type using their thoughts.

Below, we used CB Insights data to identify 21 early- and mid-stage neurotech companies working across brain-machine interfaces, neuroprosthetics, neuromonitoring, and neurostimulatory devices.

1. Kernel

Kernel is an early-stage brain-machine interface company formed and funded by Bryan Johnson, founder of the online payments company Braintree and the OS Fund. While originally intending to build memory prostheses which would allow for the external storage and subsequent upload of human memories into the hippocampus, the company has since pivoted and is now working on a way to measure and stimulate the electrical impulses of many neurons at once. The technology will be used clinically for diseases such as depression or Alzheimer’s. In November of 2018, Northwestern University professor Hooman Mohseni joined Kernel as its CTO.

2. Dreem

Dreem (formerly Rythm), founded in France and now based in San Francisco, is a neurotechnology startup that has developed a sleep-monitoring, head-mounted wearable. The device uses EEG electrodes to monitor and analyze brain activity during the course of sleep. It then uses “bone conduction technology” to modulate brain activity by emitting subtle sounds at precise moments that the company claims enhances the overall quality of deep sleep. The device is linked to an app that displays sleep metrics and personalized recommendations based on the user’s sleep habits.

3. Thync

Thync has developed a small, wearable “pod” that attaches to the back of the neck and uses neurostimulation to combat stress and promote better sleep. Their lead product, the Thync Relax Pro, uses low levels of electrical stimulation to activate nerve pathways in the head and neck. According to the company, these pathways communicate with areas of the brain to help control stress levels and sleep quality. The product is targeted towards consumers who frequently suffer from stress and consequently struggle to sleep.

4. Halo Neuroscience

Halo Neuroscience, based in San Francisco, has developed a brain-stimulating device called the Halo Sport. The device sends weak electrical pulses into the user’s brain with the intent of enhancing the efficiency of physical training. The product is based on the concept of neuropriming, i.e. using electrical stimulation to increase plasticity in the brain prior to an activity. According to the company, when paired with physical training, this results in increased strength, endurance, and muscle memory.

In May 2018, USA Cycling announced it was partnering with Halo to help train its cyclists. Halo also hired Yasi Baiani, formerly Head of Product Management at FitBit, as the company’s VP of Product in August 2018, a possible indication of the company’s intentions to pursue the consumer market more aggressively.

5. Synchron

Synchron is developing an implantable device, called the Stentrode, that aims to provide a safe way for paralyzed patients to achieve direct brain control of mobility-assistive devices. The system involves a small and flexible device that can pass through cerebral blood vessels, allowing it to implant in the brain and interpret electrical data emitted by neurons. The company is currently preparing for early-stage clinical trials to evaluate the safety and feasibility of the device to enable patient-directed brain control. Synchron’s founder and CEO, Dr. Thomas Oxley, was named the 2018 Advance Life Sciences Award Winner for his work on the Stentrode.

6. BrainCo, Inc.

BrainCo, a product of the Harvard Innovation Lab, specializes in brain-machine interface wearables. The company’s main product line is the Focus series, which offers wearable headbands for education, fitness, and mind-controlled games. BrainCo has also expanded into prosthetics, working under the name BrainRobotics. The company is developing a robotic prosthetic hand which can be controlled by the user’s mind. Using machine learning and electromyography, which measures brain signals to various muscle groups, BrainRobotics’ prosthesis product is currently capable of reproducing six distinct tactile hand gestures.

7. Neurable

Neurable is developing brain-computer interfaces that allow people to control software and devices using only their brain activity. The software makes use of machine learning methods to reduce the lag time between analysis of neural activity and output, potentially reducing it down to real-time. Neurable’s current headset uses six dry electrodes and takes two minutes to calibrate, a notable improvement on its previous design which relied upon 32 wet electrodes to monitor brain activity and a calibration process of 30 minutes. While the company eventually intends to allow patients unable to communicate to have greater control over their environment, it is initially targeting the AR/VR gaming industry.

8. Neuralink

Neuralink, the secretive brain child of electric car, solar power, and space pioneer Elon Musk, is working on building brain implants to directly link human minds to computers. The company has hired a diverse team of engineers ranging from the young brain-machine interface expert Max Hodak to leading neurosurgeon and electrical engineering PhD Ben Rapoport. While information regarding their specific approach is limited, it is understood that the company’s goal is to make AI an extension of the human brain, essentially creating a symbiotic human-AI relationship.

Musk caused a stir after hinting at the work being done at Neuralink during an appearance on the Joe Rogan Experience podcast in September 2018, in which Musk claimed that new tech would “enable anyone who wants to have superhuman cognition.”

9. Flow Neuroscience

Flow Neuroscience uses brain stimulation to treat depression. The company has developed a headset that delivers transcranial direct current stimulation (tDCS) to the forehead which, according to the company, reverses neural activity imbalances in the frontal lobe observed in people with depression. The device pairs with a smartphone app that guides the user through a 6-week wellness program.

Using Neurological electrical stimulation to treat depression isn’t new, but if the FDA approves Flow’s headset for commercial sale in the US, it will become the first tDCS product for the treatment of depression without a prescription or the supervision of a doctor.
