The details matter. We stay with them.

TechTinker AB is a Swedish limited company based in Stockholm. We build and operate our own products — from the first line of code through to operations, support and compliance.

We work against systems where mistakes surface immediately: filings that have to balance, departure times someone plans their morning around. That shapes how we build.
