Inside SAF Tehnika: Engineering-Led Culture Behind Aranet4 Success

At Aranet, we talk a lot about sensors, data, and better air. But behind every great product is something more important: engineers who are curious about how to make the world work better.

This new video features SAF Tehnika leaders Didzis Liepkalns, Normunds Bergs, and Jānis Bergs in an open conversation about the company’s journey. They reflect on the early days of SAF Tehnika, transition into indoor air quality, the challenges faced along the way, and the decisions that helped shape the company into what it is today.

You get the sense that SAF didn’t start as a “business opportunity.” It started with an engineer solving problems - wireless communication, measurement, reliability - in his own basement, and the company grew from there.

That same mentality is still visible today. Good engineering takes patience. It means testing ideas, fixing what doesn’t work, and sometimes taking the longer road if it leads to a better solution.

If you’re curious about the people and thinking behind the technology we build today, this interview is a great place to start.
