A rapidly growing start-up in the biotech field. Main requirements not limited to, but include - cloud sharing, interacting through comments and messages, being able to specify deadlines, estimated time interval, time-lapsed/remaining, assign multiple tasks (task dependencies), and label their priority level, and have integration with a nice group of tools/apps (google and so on).
I have been using this for a while and recommended to my last 15 clients who were amazed by the flexibility of the platform. It has everything You need!
Basecamp is a great product for remote teams. It is a mindset. If you're looking for a standard project management tool with lots of features, ClickUp is a great choice. It's a bit slow (especially mobile), but in terms of features, it's unbeatable.
