"Creating psychologically safe work environments is the base for high impact teams," Congleton told狗万官方. In order to recruit great employees and build strong teams, the Olark CEO says he believes it's more important than ever to create comfortable cultures.

Not sure how you can create a culture like Olark's at your business? Take it from Congleton -- here are his three tips for cultivating a supportive and open company culture.

1. Get an executive coach.

"Being a great manager is not innate. Most entrepreneurs are not born managers. There is an important distinction. A good executive coach will help you normalize reflection and continuously improve as a manager. It's a little known secret that the best managers have great executive coaches."

2. Normalize vulnerability.

"Joe Greenstein and Semira Rahemtulla from Innerspace run an incredible workshop [in San Francisco] onfounder communication. They have trained hundreds of founders on giving and receiving feedback, authenticity and values alignment. If you cannot attend their workshop, try to see your role as a leader as modeling vulnerability. Joe recommends starting meetings by taking one minute per participant to model vulnerability. Start each meeting of your executive team with, "If you really knew me now, you would know.'"

3. Practice empathy.

"Truly make the effort to listen and understand. Be curious. Learn the why, not just the what. Show kindness, and value different perspectives, experiences and ideas as though they were your own."
