Upland Software, Inc.
A maker of cloud software for businesses, this Austin, Texas company offers a suite of tools that help organizations manage content, automate workflows, and run digital marketing. It launched in 2010 under the name Silverback Enterprise Group and was renamed Upland in 2013 — a nod to elevated, cloud-high terrain. Fun fact: the company built its broad lineup by folding in dozens of smaller software tools it acquired over the years.
