Our take
Certn’s platform allows people to gain fast access to background checks, from criminal records through to motor vehicle records and even credit checks. Its software allows recruiters to save time and money in the hiring process, as the standard 3-4 days for completing background checks is reduced to hours.
Currently, the solution is used by over 2,800 enterprises, including leading employers, staffing firms and property management companies. However, it is not the only player using AI to conduct background checks; Checkr, GoodHire, and HireRight are some of the leading companies that are solving this years-old problem in different parts of the world, and Certn will have to work hard to stand out in this crowded space.
The company looks poised for a period of rapid international expansion over the next few years, thanks to considerable funding amounting to $115 million in 2023 and the acquisition of UK-based background check provider Credence and Australian Intercheck. It also astutely hired CTO Susan Davis (ex-VP of Engineering at Dessa and Xtiva Financial Systems) in 2021.
