Who We Are

We are technology marketing problem solvers

What they say

We’ll let our clients tell you what we’re really like…

We understand technology

“Sonus understands technology, and they understand the message we’re trying to take to the market. They’re excellent at explaining our technology and all of the three-letter abbreviations so prevalent in our industry. And they’re superb at then developing that knowledge for content that’s picked up by the best technology publications.”

Pragya Vaishwanar, Director Marketing - Influencer Relations, Altran

We are strategic

“We use Sonus for things that are very strategic and center to the core of our organization. Sonus helps us understand both what we want to – as well as what we should – convey to our audience. It takes much more than just a good writer or a good team of writers to translate that to paper. It takes people who actually understand your business, the market you’re in, your overall ecosystem and who can incorporate all of that into the content that’s developed, whether it’s web content, sales assets or thought leadership.”

Leila Modarres, CMO, Infostretch

We are creative

“Sonus brought us two things: rigorous organization and creative flair. Sonus identified all of the channels in which we needed to be knowledgeable, active and known, and they help us create intelligent and impactful ways to engage through those channels”

Chris Goswami, Director of Communications, ENEA Openwave

We’ve got your back

“Sonus is fantastic. They’ve got your back. They’re comfortable jumping in and jumping out of roles as needed — being responsible for an initiative, pinch hitting for us when we need extra support internally or simply supporting us by proofreading or answering questions. That flexibility is wonderful because the relationship with some agencies is much more rigid.”

Misann Ellmaker, Strategic Communications and Marketing, Optiva

We’re part of your team

“Working with Sonus is like working with your own internal team. In fact, a lot of people around our company assume that the folks at Sonus are actually VIAVI employees. For instance, they’ll search for a Sonus person in our company directory. They’re completely shocked to find that the Sonus team is an outside vendor because they work so seamlessly within our organization.”
