Write after ship
The company started as leftover release notes that always arrived late.
Stero Tech LTD makes digital kits that sit next to your product: the words, outlines and article shells that usually get written last. We do not build apps. We sell files.

Customers are individuals: indie makers, freelance builders and small product owners who buy a kit for personal or solo-product use. Typical catalog orders are €50–€200. Suites and custom programmes go higher.

Those notes became named files other people could load.
If the public kit is the wrong shape, Stero Tech LTD still quotes a private set.
Digital kits and optional custom copy files. No physical goods, no hosted SaaS.
Individual makers and small digital-product owners.
