Cisco and AI

Company strategy and engineering.

Y Combinator’s Jared Friedman interviews Cisco president and chief product officer Jeetu Patel about AI infrastructure, engineering and his career. Patel’s market forecasts come from an executive whose company sells infrastructure and security products.

Patel describes bringing a founder-style sense of urgency to a large company while trying not to alienate colleagues who work differently. He calls himself a late-stage co-founder in spirit.

He expects much greater infrastructure demand if agent use expands, though his adoption estimates and forecasts are assumptions rather than established outcomes. Cisco stands to benefit from demand for networking and other infrastructure.

Patel says Cisco encouraged AI use across its engineering organization and told employees that failing to use AI could cost them their jobs. He expects the company to need more engineers, but this is his expectation, not a guarantee of job security.

He contrasts rapid software adoption with slower hardware and silicon cycles. He describes emerging design applications while emphasizing that the maturity and pace differ across the three areas.

02

Infrastructure and trust

Data centers, demand and agent security.

Patel explains that large AI data centers need networks connecting GPUs across servers and racks. He describes Cisco’s role in this buildout, a company perspective on a market in which it participates.

Asked whether AI infrastructure is overbuilt, he says no and argues demand will expand. That is a forecast with considerable uncertainty, not proof that every project will earn an adequate return.

The conversation turns to agent security and trust in mission-critical enterprises. Patel argues that organizations need ways to control and secure agent actions before extending their use.

03

A personal journey

Career lessons and opportunity.

Patel recounts a difficult childhood in India, moving to the United States and working in restaurants. He presents these experiences as part of his personal path rather than a recipe that guarantees success.

He says ego once kept him at his own company when another role offered more learning. He encourages founders to prioritize learning, ambition and collaboration, and closes with a story about making use of opportunities.

In closing, Patel tells a story about returning to India with his daughter and encourages the audience to make use of the opportunities they have.
