HQ: New York, United States · Document AI · AI Agents · Workflow & Process Automation (RPA, BPM) · 51-200 employees · Est. 2005 · NYSE: PATH · Trust A · Hiring 93, 9 new
UiPath is a Romanian-founded American company started in Bucharest in 2005 that became the leading vendor of robotic process automation, software robots that operate other applications through their user interfaces to automate work no integration existed for. Having grown enormously on that premise, it has spent recent years absorbing the fact that language models can do parts of the same job differently, and has rebuilt its platform around agentic automation that combines deterministic robots with model-driven agents. Headquartered in New York and listed on the New York Stock Exchange, it retains one of the largest installed automation estates in the enterprise market.
