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.
Redbooth is fantastic for freelance artists, small businesses, or even larger companies. It's versatile and can handle and help you stay organized. IT has replaced most every other tool we use to stay up to date on projects, keep track of tasks, and use it for a proofing space. It may not be good if you aren't a freelancer or someone who has many tasks to complete. It seems best when there's at least 2 people in the company.
I think there's limited uses for the tool and much more comprehensive options out there for multiple tools in one. With more people working remotely, it's hard to just use email and face to face, in some ways you need to have a tool that's a fall back and a record of where you are + where you're going
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.
