Chaos is costly.

How much is poor communication costing you?

Poor communication costs large companies $62.4M and small businesses $420,000*. Per year. (Ouch.)


Put this $$$ back in your pocket while increasing:

  • Retention by 4.5x
  • Productivity by 20-25%
  • Returns to shareholders by 47%
  • Talent acquisition by a whole lot
  • And your impact by a quantum leap

*If you want the research behind the stats, get in touch. We love research!

Communicate I/O is a simple way to clear the chaos and create cultures where people feel included and inspired.
