Why, hello there. We’re Sideline

And we’re flattered you came all the
way here to learn more about us


It all started back in 2006

True story. We started making communication
apps right before the app store existed

We made some
calling apps

We made some
texting apps

Some were winners, others,
not so much. But we kept building

Then, one day in 2015 it hit us

Despite a decade of pushing mobile communication technology, our whole company still had landlines. Yes—the old, complicated, expensive and underused work phones that plague millions of desks across the nation. A few light bulbs later, Sideline was born.

Here’s what we’ve done so far

  • 121 million+phone numbers
    given out
  • 3.3 billion+calling minutes
  • 100 billion+text messages
