Founded in 1972, Kastle Systems is a building and security systems provider that employs 700 people, including over 100 Virginians.
An investor, entrepreneur and philanthropist, Ein also is a minority owner of the Washington Commanders, which plans to build its new stadium on the RFK Stadium site.
In March, Kastle bought a majority stake in Sterling-based building security company i2G Systems. Although the company did not disclose financial terms, Kastle officials said this was its largest ever investment.
Ein is founder and owner of MDE Sports & Entertainment, which owns the management rights of the Mubadala Citi DC Open tennis tournament through its MDE Tennis company, the Washington Justice esports franchise and Washington City Paper. Ein also started the Washington Kastles, a World TeamTennis franchise.
Arguing for an upgrade to the Rock Creek Tennis Center, where the Citi Open is played, Ein has proposed adding more tennis courts and a community center to the property.
Before starting his firm, Ein worked for the Carlyle Group, Brentwood Associates and Goldman Sachs. He received a bachelor’s from the University of Pennsylvania’s Wharton School and an MBA from Harvard Business School.
