The companies in Palo Alto are primarily established software development firms and IT services providers. They range from very large corporations like HP, which creates technology solutions, to mid-sized companies such as VMware, a leading provider of multi-cloud services, and Rubrik, specializing in Zero Trust Data Security. There is also a presence of newer, AI-focused companies like Navan, an all-in-one travel app, and SymphonyAI, offering AI SaaS solutions. Many of these companies focus on B2B solutions, digital transformation, and data management.
A notable pattern among these companies is their strong emphasis on software development and artificial intelligence. Companies like Glean, founded in 2019, and DevRev, founded in 2020, are relatively young but already significant in employee count, indicating a robust environment for growth in these sectors. The presence of both long-standing IT giants and newer AI specialists highlights a continuous evolution in the technology landscape of Palo Alto.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
