A staffing agency acts as a middleman between employers and job seekers. They help companies find the right candidates for temporary, permanent, or contract roles by sourcing, screening, and placing talent. Staffing agencies make money by charging employers a fee, typically based on a percentage of the employee's salary or an hourly rate for temporary workers. For a staffing agency startup, it’s important to build relationships with businesses, understand industry needs, and provide value by matching the right talent with the right roles efficiently.
