The SaaS 1000 is a list that highlights the top growing SaaS companies based on a proprietary algorithm that includes hiring trends, growth indicators and number of employees. We have created a seamless algorithm that tracks a SaaS company’s 6 month employee-size growth, and overall employee size, to come up with the SaaS 1000 ranking. The list will include the largest SaaS companies to smaller startups. In order to rank on the SaaS 1000 list, you must have between 40 and 1000 employees. In addition to the list and numbers below we also have the ability for you to see the alternatives and competitors of each one of these SaaS providers. You can export the Top 1000 to view the complete list as a CSV. The list is updated quarterly.
