About the name: "Tempo" means "time" in Italian. It's a term often used in two pursuits near and dear to our Founder's heart: music and running. In music, the tempo is the song's speed, and an "uptempo" section is performed at a faster speed. Similarly, a "tempo run" is a faster workout, pushing one's body to adapt accordingly. Along the same lines, the UpTempo Group aims to help revenue orgs improve the pace of their company's growth, achieving goals faster!
