Brain wearable device manufacturer Halo Neuroscience has raised $1.5 million funding round led by Andreessen Horowitz’s Marc Andreessen and SoftTeach VC’s Jeff Clavier.

Halo has already received a lot of clients wanting to boost the function of their brains through applying electricity directly in unsupervised conditions. One of Halo’s founders said that the device does not work as a “One Flew Over The Cuckoo’s Nest simulator.”

Amol Sarva said, “Halo’s technology employs a range of non-invasive, low energy, battery operated stimulation modalities that work on the nervous system to boost cognition. Halo builds on the field of neuromodulation, where recent science has employed electromagnetic waveforms, infrared light, ultrasound, physical and other stimulation techniques.”

The new funding round raised by Halo would be used to address safety issued with the food and drug authorities. This would help the company get approval that its product doesn’t create a hallucinating effect.

Halo was established by Dan Chao, a neuroscience researcher at Stanford, consumer mobile guru Amol Sarva and engineer Brett Winger.
