For tracking company department headcount changes, we offer multiple options. Our "Find Company Headcount Growth" action provides detailed employee count data over time. Additionally, the "Employee Count by Department" data point can give you a breakdown by department. However, the best source may depend on the specific company you're researching. For traditional SaaS or established firms, our enriched company action might be reliable. For smaller businesses, web scraping could be more accurate. We recommend trying these options to see which provides the most comprehensive data for your needs.
