Although our assigned assistant lives in a distant place, since using the services of CasterBiz, we have been able to explore various industries. In order to find a new kind of business, often we need information that is normally hard to find and takes a lot of patience to uncover. We’ve enlisted the help of Caster Assistants many times, and are always pleased with the great information they’ve found. We’d like to use CasterBiz even more, which will allow us focus on the things we need to think about.

Basically, we are a company managed only by two people, so routine tasks really take a big bite out of our time. After asking for the help of CasterBiz, whatever task we write on the task management tool gets taken care of automatically. Since crowd-sourcing can now be used for progress management, I wonder to what other tasks they can handle. I look forward to using their services again.

As a freelancer working in public relations, I have been able to use CasterBiz for various things as selecting newspaper headings, searching information about the person I'm about to meet, making questionnaires and dining reservations among others. When I tried to request for them make a press release, I was surprised of the exceptional quality of the finished product. For a freelancer, routine tasks that are outside of our core business tend to take lot of time, but thanks to CasterBiz, my workflow has never been this efficient. I'm looking forward to using your services again in the future.
