The technology backbone developed by Test Double made this project possible at the scale that was achieved. Test Double instantly jumped in to help bring the Curbside Concerts project to life. By providing two developers they worked several weeks to stand up the online interface and a custom scheduling tool to receive concert requests and schedule routes for the driver and artist that enabled us to bring joy to over 700 seniors amidst the height of the pandemic.

Empathetic Collaborators
Each and every Test Double agent brings a spirit of empathy, humility, and earnestness to their work. They bring new and exciting ideas to the team without a lot of fanfare or ego. They coach and educate without being corrective or judgmental. They empowered our employees to lead efforts and encouraged them along the way. They became part of the fabric of the team—not them and us, but one team.
