Braintree Sale to PayPal
Bryan Johnson sold Braintree, a payment gateway company he founded, to PayPal in 2013 for approximately $800 million. The acquisition made PayPal a dominant force in mobile payments at the time. Johnson's Braintree had previously acquired Venmo, which became a massive success under PayPal's ownership. Forbes reported the deal details.
The Braintree acquisition gave PayPal access to a robust developer platform and a portfolio of payment technologies. Johnson, who was in his late twenties at the time, used the proceeds to fund new ventures. The sale is often cited as a landmark deal in fintech, demonstrating how a single platform could be integrated into a global payments giant. SEC filings detail the transaction.
Kernel: The Neuroscience Company
After selling Braintree, Bryan Johnson founded Kernel, a neuroscience company focused on developing brain-computer interfaces. Kernel's mission is to create devices that can monitor and record brain activity with high resolution. The company has raised significant venture capital to advance its research and development efforts. Forbes covered Kernel's technology goals.
Kernel has been ranked among the most innovative startups in the neurotechnology sector. The company's flagship product, the Kernel Flow headset, uses time-domain functional near-infrared spectroscopy to measure brain activity. Johnson has publicly stated that Kernel aims to make brain data as accessible and useful as other personal health metrics. The company continues to operate independently and has not been sold.

Braintree's Legacy and Market Impact
The sale of Braintree to PayPal fundamentally reshaped the digital payments landscape. Venmo, which Braintree acquired before the PayPal deal, grew into a cultural and financial phenomenon. Today, Venmo is a household name for peer-to-peer payments in the United States. The Braintree platform continues to power payment processing for major merchants and ride-sharing apps.
Analysts credit the Braintree acquisition with giving PayPal a critical edge over competitors like Square and Stripe in the early mobile payment era. Johnson's ability to build and exit a high-growth company has made him a prominent figure in the startup ecosystem. His subsequent focus on neurotechnology and longevity science reflects a shift toward deep science ventures.
