Head of Product
"Our cross-functional teams use so many apps. There are a lot of balls to keep in the air and using GC we never drop them. Highly recommend!"
Kevin H.
Head of Product & Design
"Our team uses so many tools. Each has its own comments, notifications, etc. It used to be impossible to keep up with but [with GC] now I literally never miss a thing."
James A.
Senior Product Manager
"I never knew how much time I lost waiting on notifications. Or how often I'd never get a notification at all! With GC, I respond faster, and that helps us get things done faster."
