The success of a company is often defined by two key factors: how your customers feel about you and how your employees feel about you. We’re excited to share that recently we’ve had some great validation by both!

Customer validation

We’re very honored to work with a variety of innovative companies that are breaking the status quo with open networking principles in data centers designed to scale. All of our customers have realized the need for an open, modern data center and are looking to build infrastructure with purpose. From web-scale giants to visionary enterprises, we give them all the ability to build something “EPIC.”

This was recently highlighted when for the second year in a row, our customers have rallied around our vision for the future of data center networking and recognized us as “The Best Data Center Networking 2019” with their reviews through Gartner Peer Insights.

As Gartner puts it, “The Gartner Peer Insights Customers’ Choice is a recognition of vendors in this market by verified end-user professionals, taking into account both the number of reviews and the overall user ratings.” To ensure fair evaluation, Gartner maintains rigorous criteria for recognizing vendors with a high customer satisfaction rate.

This distinction is one of the proudest ones and we’re naturally in love that this directly related to the amazing reviews we received from our customers. Check out just one of our favorites that showcases not only the love of our product but our “Happy to help mentality” (part of our Cumulus culture):

Employee validation

Moving along on the validation train, we were also recently recognized as one of the 50 Highest Rated Private Cloud Computing Companies To Work For in a list released by Battery Ventures, a global investment firm and cloud investor, and Glassdoor*, one of the world’s largest job and recruiting sites. The list highlights 50 privately held companies—all business-to-business, cloud-computing companies—where employees report the highest levels of satisfaction at work, according to employee feedback shared on Glassdoor.

The distinction placed Cumulus Networks at an overall company rating of 4.6 while the broader average across Glassdoor is 3.4. CEO, Josh Leslie, boasts a 94% approval rating on Glassdoor—compared to an average of 69% for all approximately 900,000 employers on the site–and the company has an 88 percent positive business-outlook rating, again based on the feedback shared by employees. The broader Glassdoor average is 49%. A positive business outlook means employees believe business will improve in the next six months.

We’ve really worked hard at creating a culture of openness and transparency here at Cumulus Networks and we’ve had a lot of success with that approach” says Sandy Palicio, VP of Human Resources. She continues, “One of the reasons I believe Josh’s approval rating is so high because he “practices what he preaches. There are tangible examples of this in action. From our weekly all-hands meetings where employees have the chance to ask any question from Josh and get a real and honest answer from him to sending out e-staff meetings minutes to the whole company.”

This is the third year Battery has issued the list, along with a related ranking of the 25 Highest Rated Public Cloud Computing Companies to Work For. The rankings highlight the broader trend of businesses increasingly turning to the cloud to run critical technology systems and software, instead of using on-premise systems.

They also “highlight the increasing importance of cohesive culture and employee happiness in running a successful business,” said Neeraj Agrawal, a Battery general partner who specializes in cloud investing.

“The private companies on this list have not only scaled their products, teams and business functions—but they’ve managed to scale culture,” Agrawal said. “We view these rankings as a key indicator of company health and longevity, and we hope all companies on this list view it as an honor to be included.” It was also more difficult to make the list this year, compared with last year, Agrawal added. A Glassdoor economic research study, as well as other third-party studies, show that companies with high employee satisfaction often post stronger financial performance.

Glassdoor noted that employees at these highly rated companies commonly mentioned in online reviews that they enjoy working for mission-driven companies with strong and unique company cultures; employers that promote transparency; and companies with experienced senior leaders who regularly and clearly communicate with employees. For instance, according to one anonymous employee review of Cumulus Networks on Glassdoor:

After all that, it almost goes without saying that we’re stoked for our year so far. With the good vibes from our customers and employees along with the product updates to Cumulus Linux and Cumulus NetQ, 2019 has shaped up to be another banner year and we haven’t even crossed the half-way point!
