JFrog provides a bunch of products and services around DevOps, i.e. taking your software and deploying it to the world. Their most popular lines deal with package and dependency management.
Software is mostly developed locally (on a personal computer), and then later deployed remotely to a group of powerful servers to run in “production”
The process of deploying that software - especially as teams use more and more open source packages - can get pretty complex
JFrog provides products that take your local software and get it ready for deployment, manage those packages, scan for security vulnerabilities, and other nice things
Adoption is comically high, with literally 75% of the Fortune 100 as customers (seems suspicious tbh). JFrog IPOd in 2020, and their market cap at the time of writing is around $5B. So they’re definitely on to something.
