There have been some major moves occurring at companies focused on the future of work in the last few months. Robotic Process Automation, a technology that makes it possible to automate repetitive tasks inside businesses, is on fire. UiPath, arguably one of the standard bearers for the RPA industry, just raised a huge round that values it at more than $3 billion after growing from $1 million to $100 million in revenue in less than two years. Human work aggregators also are doing extremely well. Freelance platform Upwork just had a successful IPO, and TaskUs, a next-generation business process outsourcing firm, just raised $250 million from Tiger.
