Our research follows 7,547 researchers, builders, lab leaders and public voices through cited biographies. Missing career records can lower counts. Outdated roles can overstate current counts and change ranks. Publication numbers from OpenAlex, as of 22 October 2026. Career and profile data as of 22 October 2026.
We estimate that 11 people shaping AI have worked at Cisco Systems, including 3 (27%) here now and 8 with former affiliations. Among 3,344 companies, the group is tied for 56th on current people and tied for 60th on all-time people. Policy, ethics and society leads 7 areas of expertise (3 of 11 people with profile topics), and researchers make up 3 of the 3 people here now (100%). In dated work stints through 2025, active headcount peaked at 4 people in 2010 and 2014 and stood at 1 in 2025. Across dated career transitions, we record 6 full moves in and 4 out.
