Built quietly,
in the open.
Terasa is a personal private cloud for your health data — every wearable unified in one app you actually own. Here's where it came from, who's building it, and how it runs.
Where it comes from
Terasa grew out of Thinkin' Rocks, an applied engineering lab at the intersection of software, hardware, and research.
The question that started it was a simple one: the devices we wear every day know a great deal about us, so why is that data so scattered — and so rarely ours? Terasa is the answer, being built in the open.
Who's building it
Terasa is built by Yerzhan Zhamashev, a software engineer based in Helsinki, as part of Novel Systems.
Yerzhan is a graduate from Aalto University who works across software, hardware, and research. Terasa is his attempt at health software that feels calm and high-craft, where data is unified, understood, and genuinely owned.
How your cloud runs
UpCloud
Every person's cloud runs on its own European infrastructure — independent, and genuinely yours.

Each private cloud is a small Kubernetes deployment, so it stays portable and reproducible.

Your data follows the Open Wearables standard — vendor-neutral, and never locked in.
