We collect millions of network and media quality metrics from our customers around the world. We analyze, cluster, and categorize them based on various attributes. Our cloud infrastructure creates reports and alerts the customers when their users experience degrades. Our systems also attempt to automagically fix issues. The optimizations empower our customers to provide a superior service quality compared to their competitors.

Our team is made up of engineers that have shipped code for various networking companies.

We are backed by the best! True Ventures from Silicon Valley and Lifeline Ventures from Helsinki have invested into us. Read the press release for details.

Our culture

  • Our solutions aim to excite our customers daily.
  • Data is the critical part of our product. We constantly raise the bar on the user-experience.
  • Rome was not built in one day. All our projects start small and gradually increase in complexity.
  • We are constantly shipping code. Done is better than perfect – the moment when the feature is better than what is already live on the site.
