GanttPRO's answer
It all started in 2014. The team that stood at the origins realized that there were no tools on the market that could help them comprehensively work on tasks and projects with a full picture at hand. With that in mind, the goal was set - to create the best Gantt chart experience for project management.
Years later, GanttPRO has 1M+ registered users and hundreds of awards from leading software review platforms.
