The Hub is your personal homepage to Gtmhub as it allows you to conduct most of your OKR workflow from the Hub itself.
By default, you will have the options to see yours and your team's OKRs on the left:
Review your team progress from the Hub
To review your team progress, select a team that you've been assigned to. Your teams will be displayed under "My OKRs".
Gtmhub allows you to also customize specific filters. This function allows you to browse and update your teammates' OKRs or the OKRs of specific individuals or teams in your company.
