Pros
ClickUp grew so fast in 5 years for a reason. They stay ahead and develop extremely fast. The company is young and hungry to compete in the toughest space. They've built a culture of people ready to dive in and pull off tough projects. The CEO is exactly who you want leading the company. He will dive in with every team and can quickly add value in a big way. They're extremely scrappy and find ways to solve big problems rather than shy away from them. Watch out for big moves coming in the second half of this year from ClickUp!
Cons
They've had to make some tough decisions that not everyone likes as every company has, but I like that they're at the forefront of these type of moves and not waiting until its too late. They're also a young company but they're learning fast and adapting to any mistakes they see quickly.
