From a platform that employers can use to test software development job candidates to software that aims to improve how companies deploy field services workers, software-as-a-service (SaaS) companies have made a splash in transforming workplaces in 2021.

Some of the largest employers had to adopt remote working this past year and have declared a willingness to keep some form of it even after the global pandemic subsides, prompting a renewed interest in software tools that can improve and even change business operations in a variety of industries.

With headquarter locations including San Francisco and St. Louis and Kissimmee, Fla., these startups show that not only does innovation happen anywhere, but that startup funding remains strong and good ideas don’t only happen within the largest tech giants.

Here are the SaaS startups that have caught our attention so far.
