Roblox is an American company founded in 2004 that operates a platform where users build and publish their own three-dimensional games and social experiences for other users to play. Its economy runs on a virtual currency called Robux, which players buy and spend inside experiences, and a share of which is paid out to the creators who make them, so the company earns from the platform rather than from producing games itself. Headquartered in San Mateo and listed on the New York Stock Exchange since 2021, it reports tens of millions of daily active users, skewed heavily toward younger age groups.

Skydio is an American drone company founded in 2014 by MIT engineers who had worked on Google's Project Wing, and it built its reputation on autonomous flight rather than on airframes. Its aircraft navigate and avoid obstacles using onboard computer vision without relying on satellite positioning or a skilled pilot, which is what allows an untrained operator to inspect a bridge or clear a building. Headquartered in San Mateo, it exited the consumer market in 2023 to concentrate entirely on public safety, defence and infrastructure inspection, where it is the largest American drone manufacturer.

Headquartered in San Mateo and privately held, it sells to schools, healthcare providers, retailers, manufacturers and local government, and has grown quickly in a category that had seen little product change for years.
