Our take
The existing processes for referencing and background checking suffer from notable inefficiencies, marked by biases, time-consuming procedures, and an intimidating experience for candidates. Addressing these challenges, Zinc Work aims to solve these processes by introducing an automated reference and background-checking solution.
Setting itself apart in the market, Zinc Work focuses on the user-friendly design of its solution, its swift integration into existing Applicant Tracking Systems (ATS), and its high level of customisation. With a vision to offer a solution for background checks, Zinc covers a spectrum from criminal record checks to financial, education, identity, employment, and reference checks.
Funding secured in 2023 was led by esteemed financial services investor AVP (AXA Venture Partners) and supported by Seedcamp, and will facilitate the launch of groundbreaking industry initiatives. These include the introduction of the first reusable global Right To Work check, the first Employment verification reference integrated with HMRC, and a background check template library collaboratively contributed to by over 40 Zinc Work customers. This financial injection underscored Zinc's commitment to innovation and reinforced its position as a trailblazer in the realm of automated reference and background checking solutions.
