Zirtual was a virtual assistant service that provided remote administrative support to entrepreneurs, executives, and small teams. The company's assistants, known as ZAs, were based in the United States and were trained to handle a variety of tasks, including scheduling, email management, travel planning, and research. Zirtual used a subscription-based model, with clients paying a monthly fee for a dedicated assistant. The company was acquired by Startups.co in 2016, after briefly shutting down due to financial difficulties.
