Ongig recently released its fourth Top 100 Applicant Tracking Systems in 2018 report, which measures 118 Applicant Tracking Systems (ATS) platforms out of more than 1,000 on the market. The report, which is incredibly robust, pulls ATS information from more than 4,200 employers. In summary, Taleo has fallen behind the marketplace and Greenhouse is getting most of the market share increase. Google Hire has become a threat to all SMB ATS providers and iCIMS and Workday are growing at high rates.
