Underline has become an indispensable partner in the economic growth story of Colorado Springs and the broader region. Over the last three years, Underline has delivered on every commitment—forging deep partnerships with the business community, working hand-in-hand with the Chamber on our stated priorities, and elevating the conversations that drive our City forward. Underline has proved that a private company can be a genuine community partner: showing up, delivering, and raising the bar for what private investment can look like.
As a university with a growing research footprint, defense-adjacent programs, and a campus that demands high-availability connectivity, we can't afford to work with partners who just meet the minimum.
