A tale of technological ingenuity and a love story
Cisco’s founding in 1984 is as much a tale of technological ingenuity as it is a love story. Leonard Bosack and Sandy Lerner, the company’s founders, were both Stanford University employees—Bosack managing the computer science department’s network, while Lerner oversaw computing at the business school. Though they worked in separate buildings, their connection grew from both personal and professional synergy. The two sought a way to communicate over Stanford’s computer network, which was segmented and isolated by design, making inter-departmental messages impossible. In fact, the university’s departments were housed in different buildings, and, adding an inventive twist, the pair used Stanford’s sewage pipes to run cables, linking computers and enabling network communication.
To solve the network divide, Bosack adapted a piece of routing software initially created by Stanford researcher Bill Yeager. This software could bridge networks with different protocols, enabling seamless communication across campus. The project began as a means of personal connection but soon revealed a larger potential to solve the broader networking needs in academia and business. With this insight, Bosack and Lerner saw an opportunity to commercialize their innovation, leading them to found Cisco.
However, Stanford soon challenged their ownership, asserting that the router technology was developed on university grounds and therefore belonged to Stanford. After lengthy negotiations, the university allowed Cisco to license the technology, clearing the path for its commercial use. The couple then left Stanford to focus fully on Cisco.
In 1987, Cisco secured a crucial $2.5 million investment from Sequoia Capital, marking the company’s shift from a small startup to a structured corporation. Sequoia appointed John Morgridge as CEO to bring the operational experience necessary to scale. Under Morgridge’s leadership, Cisco expanded rapidly and went public in 1990, establishing itself as a pioneer in network technology. By bridging computers and, quite literally, spanning buildings, Cisco's routers laid the groundwork for connecting entire businesses, propelling the company into industry dominance and transforming it into a networking giant.
