These entrepreneurial landlords do. The address 165 University Avenue may not mean anything to you, but maybe these companies will: Google, Logitech and PayPal. What do they all have in common? They've all been tenants at the same Silicon Valley building owned by the Amidis, a family of Iranian immigrants, along with business partner Pejman Nozad. "We believe in good karma, good energy, good feeling, and we believe some buildings have good energy," said Saeed Amidi. During the dot-com boom, Amidi and Nozad invested in several of their tenants, though they refuse to discuss their returns. But they did invest in PayPal, which sold for $1.5 billion to eBay, garnering a multimillion-dollar payout for Amidi and Nozad. Now, they’re hoping the luck follows them to their own entrepreneurial venture, a 150,000-square-foot building in Sunnyvale, near Palo Alto, called Plug and Play Tech. Here, startups can rent space and enjoy other amenities including a gym and cafeteria. So far, luck is on their side: Connections made at Plug and Play have helped tenants find about $200 million in financing.
