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).
A good collaboration tool was always a big challene in the most team I've met. The main challenge is there are many tools with tons of features. They'r all great in the paper. But in practice, the team usually doesn't enjoy collaborating using them. This is the challenging part. The project management tools should be well designed to keep simplicity in combination with well-chosen features to bring the most productivity and activity among the team. I'm thinking about many of my stacks, ClickUp is one of the few choices which I've never thought about migrating about. I can't describe it in text, I just advise you to try it once and you'll understand. The team behind ClickUp is really active. They really care about delivering new features.
