About Codility

Our Story Our story started in 2005 when Greg, our founder, was looking for a quick way to recruit the 20 additional software engineers needed by the IT start-up he worked for in China, while at the same time saving time, money and avoiding stress. The result was the beta version of Codility: a tool to filter out the 90+% of candidates who are unable to deliver correct solutions to easy programming tasks. In 2009 we won the Seedcamp competition and soon afterwards registered in London, UK where we continued to grow, drawing only from that original investment. Over the next few years, Codility developed very quickly and moved to Warsaw, Poland, where most of the team is now based. Since then, more than 1200 companies in over 120 countries have used Codility and over 4953717 tests have been assessed.
