Kernel

Overview

Kernel is a neurotechnology company developing non-invasive brain-computer interface (BCI) technology. Founded in 2016 by Bryan Johnson (founder of Braintree and payments company Block), Kernel's mission is to develop advanced neural interfaces to understand, honor, and enhance the human brain[@kernel].

The company focuses on non-invasive approaches that can be used without surgery, making brain computing accessible to a broader population. Kernel's technology aims to enable applications in cognitive enhancement, medical monitoring, and human-computer interaction.

Company Information

• Founded: 2016
• Headquarters: Los Angeles, California, USA
• Founder/CEO: Bryan Johnson
• Funding: Over $110 million (Series C)
• Employees: ~100

Technology Platforms

Kernel Flow

Kernel's flagship product is Flow, a non-invasive neuroimaging device based on functional near-infrared spectroscopy (fNIRS). Flow measures brain activity by detecting changes in blood oxygenation using near-infrared light.

Key Features:

• Non-invasive: No surgery required - wearable headset
• Portable: Can be used in various settings
• Continuous Monitoring: Real-time brain activity tracking
• High Spatial Resolution: Better than standard EEG
• Cognitive Metrics: Measures attention, focus, and cognitive load

Kernel Mind

Kernel Mind is the company's AI-powered software platform that analyzes neural data from Flow devices, providing insights into cognitive states and brain health.
