10000ft

If you run any type of operation where you have to manage multiple resources and you need to move those resources from within projects or clients, this is a super useful tool. You can forecast work and allocations. It gives you a clear, very visual illustration of how your resources are going to be utilized.
It is a great tool, not only for the operations department, but for other departments like sales (to see future availability), human resources (to see future needs of people), finance (forecasting of sales and expenses).

They have been super responsive every time we need them. We built ourselves some integrations with other internal systems, and whenever we needed clarification or help to complete said integrations, they were super responsive. They have a very technical background which makes it super easy to work with when you present to them technical challenges regarding integrations or the use of their API.

I think 10000ft is good for bare minimum project monitoring, we used it a large company because we didn't need to have exact numbers - it was just a rough idea to see where freelance resources were over burning. If, however you work a much smaller company and really need to know detailed information it's not as effective, there are many other software options that really allow for much closer and precise tracking.

I would recommend 10000ft for companies that just need to monitor large freelance teams, track hours and higher level projects that are also monitored on other project management tools. It's a tool I would only use in conjunction with something else.
