Cisco Systems Inc. was founded in December 1984 by Leonard Bosack and Sandy Lerner, a married couple who were computer scientists at Stanford University. Their work at Stanford involved connecting disparate computer systems, and they pioneered the concept of using a local area network (LAN) to link distant computers over a multiprotocol router system. This innovative approach became the bedrock of Cisco. Initially, they operated the company out of their home, with the name "Cisco" derived from San Francisco, and its logo a stylized depiction of the Golden Gate Bridge.

Cisco's initial business model centered on selling networking hardware, specifically the multiprotocol router. This groundbreaking product allowed different computer networks to communicate seamlessly, a crucial capability for building the early internet. Their first product, a network interface card for Digital Equipment Corporation's computers, was sold in 1985, followed by their first major success, a router that supported multiple network protocols, in 1986. This early innovation positioned Cisco as a leader in the nascent networking industry.

The company faced several significant challenges in its early years. As academics, Bosack and Lerner initially lacked entrepreneurial experience and largely self-financed the company. As order flow increased, they sought venture capital, with Sequoia Capital investing $2.5 million in 1987 and taking effective control. Cisco also encountered intellectual property disputes with Stanford University regarding the router technology developed by Bosack and other Stanford staff. This was resolved in 1987 when Stanford licensed the router software and two computer boards to Cisco. Scaling operations and navigating market uncertainty in the nascent networking industry were also hurdles. Cisco addressed this by going public in 1990, raising capital for expansion. Furthermore, management disagreements arose after Sequoia Capital appointed John Morgridge as CEO in 1988. This led to Sandy Lerner's ousting and Leonard Bosack's resignation in 1990, shortly after the IPO. Despite the founders' departure, Cisco continued its rapid growth. By 1991, facing a deluge of customer service calls, Cisco expanded its engineering team, extended support hours, prioritized calls, and integrated remote network diagnostics.
