The Preseem and Aterlo Networks Story

Aterlo Networks is the creator of Preseem, a cloud-based platform that helps local and regional Internet Service Providers (ISPs) delight their subscribers with lower support costs by measuring, analyzing, and optimizing network performance to improve the subscriber experience.

Aterlo was founded in 2014 when a team of network industry professionals with over 30 years of combined experience created a buffer-free streaming solution called NightShift. This initial product enabled people living in remote areas to effortlessly stream high-definition videos regardless of the quality of their internet connection.

By 2017, thanks to valuable insights gained from customers, the team realized there was a larger opportunity to better serve rural communities and went to work on developing a new product named Preseem.

With Preseem, Aterlo expanded its focus from optimizing video streaming for internet subscribers to improving all aspects of the subscriber Quality of Experience (QoE). Preseem now provides real-time network monitoring tools that help ISPs proactively address issues and deliver consistent, high-quality internet to subscribers. This helps ISPs meet the ever-growing need for streaming, online gaming, video calls, and reliable internet access and speed.

As we’ve grown, we’ve been honoured to be recognized by our industry peers. In 2021, Preseem was named WISPA Service of the Year for the third year in a row, and our annual Fixed Wireless Network Report has become required reading for ISPs around the world. Aterlo was named one of the top 17 hottest Waterloo tech companies by Founders Beta in 2021, and the same publication also named us one of the top 100 tech companies to watch in 2022.

Fast forward to right now, and we’re excited to expand our platform with the launch of our new Preseem Essentials and Plus packages for ISPs. These include innovative new RF/CPE metrics and analysis tools that help our customers move to proactive management of their networks while reducing subscriber churn, optimizing staff expertise and network ROI, and lowering operational costs.

Where We Are Now

Today, Preseem is the sole focus of Aterlo Networks. By providing premium customer service and developing our product to meet the needs of our customers, Aterlo has been able to achieve rapid, organic, customer-driven growth.

As a result, Aterlo now has over 25 employees, over 400 active deployments around the world, and a healthy pipeline of new products to help serve a growing market.

“The Preseem mission is to enable local and regional ISPs to thrive, by solving network problems with products that people love,” says Gerrit Nagelhout, CEO and co-founder of Aterlo. “We recognize that it’s not enough to just solve problems, which is why we build products that our customers are also champions for.”

Fun Fact: People ask where the name Preseem comes from. Well, the truth is the name just popped up one day and we’ve loved it ever since!
