Colin Day is the founder and chairman of iCIMS, the leading provider of recruitment software solutions.

After graduating from Cornell University and getting his start as a recruiter at Comrise Technology, an IT staffing firm, Day established iCIMS in 2000 with a vision to deliver applicant tracking software emphasizing ease-of-use and unparalleled customer service. Under his leadership, iCIMS has grown to become the market leader for cloud-based recruiting solutions and has been recognized by Inc. 500|5000 as one of America’s Fastest-Growing Private Companies for 13 years.

Day maintains a deep commitment to customer needs, leading iCIMS to remain solely focused on delivering a suite of world-class, enterprise products to more than 4,000 clients, including dozens of Fortune 500 brands. With approximately 1,000 employees and more than $200 million in annual recurring revenue, the company is the largest recruiting software provider across mid-market and enterprise segments. iCIMS has also expanded its product portfolio with company acquisitions, including JobMagic, for social recruiting (2012), TextRecruit, for mobile candidate communications and artificial intelligence (2018) and Jibe, to power recruitment marketing capabilities across dynamic, branded career sites and candidate relationship management (2019).

Day is widely recognized as a dynamic business leader, named one of the Highest Rated CEOs on for Small and Medium Companies in 2019, 2018 and 2015, and one of The SaaS Report’s Top 50 SaaS CEOs of 2019, 2018 and 2017.



  1. Truly puts employees first! Not only does Colin ‘talk the talk’ but he ‘walks the walk’. He takes the time to sit with anyone that wants to, to hear them out. He truly has an open door policy and genuinely cares. He has made it his personal challenge for the company to absorb the rising cost of healthcare. In 8 yrs w/ iCIMS, my insurance premiums only went up one time and that was due to adding my child. This is just one example of how awesome Colin, and iCIMS as a whole are!

  2. Colin is incredibly transparent with all of us about his vision for the company. You always know exactly where we stand as a company, and what we’re focusing on; even as an individual contributor, you never feel like you’re in the dark, which I think is incredibly rare for a company of this size. His energy and passion are admirable, and he’s great at infusing both into the entire company. You can tell he really cares about the company, how it’s run, and his employees.
