TeamGantt is a project management software company that specializes in simple and intuitive gantt chart tools for project planning and collaboration. Founded in 009 by John Correlli and Nathan Gilmore in Baltimore, Maryland, TeamGantt was created with a single purpose in mind: to bring calm and clarity to teams who work together.TeamGantt was originally founded in 009 by John Correlli and Nathan Gilmore under the name Groundbreaking Designs LLC.At the time, John and Nathan were both developing software for a large roofing contractor in Baltimore, Maryland. They searched high and low for a good way to schedule and collaborate on projects online but couldn't find a solution that did both well. They decided to tackle the challenge of building their own gantt chart software on nights and weekends.After seeing their software’s potential, John and Nathan released an early version for other companies to try. It turns out, they weren’t the only ones who needed a better way to manage projects! The first public release of TeamGantt officially launched in November 010, and John and Nathan had their first customer within a few hours. TeamGantt quickly took off, attracting big-name customers like Twitter, Expedia, and Turner Broadcasting in just the first year.After the successful launch of TeamGantt, Groundbreaking Designs LLC rebranded to match its flagship product. Now, our company and software platform are both known as TeamGantt.
