The Golden Gate Bridge in San Francisco
Len Bosack and Sandy Lerner at Stanford University started Cisco. Bosack was Director of Computer Facilities for Stanford's Department of Computer Science, and Lerner was Director of Computer Facilities for Stanford's Graduate School of Business. Bosack designed the original logo, based on San Francisco's famous landmark - the Golden Gate bridge. Incidentally, Cisco's name comes from the last 5 letters of the city's name! ( FRAN-CISCO)
75 venture capital companies rejected Cisco, before Don Valentine, founder of Sequoia Capital finally put $2.5 million in the business in 1988. The money was never used, as sales of the company's routers rocketed. Cisco is now the world's leading supplier of enterprise internetworking solutions that link geographically dispersed LANs and WANs to form a single, seamless information infrastructure.
