For nearly a decade, Bandwidth has been a pioneer in the market for communications-as-a-service. The company's offering, which combines a cloud-based communications platform with a Tier-1 carrier network, underlies some of the world's most widely used videoconferencing applications. With much of the world working from home, Bandwidth had a banner year in 2020, despite the global financial chaos.

"After several successful rounds of raising capital, Bandwidth was already growing at a fast pace when I joined," says treasurer Scott Taylor, "but the accelerated shift to the cloud in the last year certainly gave us an extra lift. We also closed a large acquisition [of Voxbone] that was transformative for our organization, helping us move into new markets internationally where we didn't previously have a presence. We now serve around 60 countries, whereas before the acquisition, we covered about 15. All in all, 2020 was a big year for us."
