Artificial intelligence (AI) software start-up Airts has landed a six-figure contract with accounting giant PwC for its system that helps to manage the workload of employees. The Edinburgh-based firm, which launched in 2013 and has an eight-strong team, is now preparing to roll out its software, dubbed Braid, to more clients across the UK and overseas on the back of the deal with the PwC service delivery centre in Poland. Its software aims to ease the burden on employers and staff of managing their workloads by using AI to automate schedules and allocate tasks depending on factors such as their capacity and skills. Chief executive and co-founder Andrew Bone said: "Major professional services firms like PwC constantly have to decide how best to allocate staff to client engagements in a way that balances the competing needs of the customer, the wellbeing of staff and, ultimately, the bottom line. Braid supports companies to overcome this challenge at scale by optimising the schedule as circumstances change." Airts, co-founded by chief technology officer Dr Alastair Andrew, has been supported by business accelerator programme Entrepreneurial Spark and last year raised £300,000 of seed investment from Scottish angel investors to fund its growth.
