Sustainable software, built to last
Heivol is a Denmark-based holding company building sustainable software products. The entire stack is locally hosted in Denmark — no hyperscaler, no US cloud. Flagship: Heivol Assistant — a private personal AI that runs on its own VM. No enshittification. No surveillance. No training on your data.
There is a natural limit to how profitable a product should be. When margins grow too large, one of two things happens: prices come down for customers, or the surplus is invested into something new that makes the world more sustainable over time.
Margins don't grow forever. Surplus flows back to customers or into new products that deserve to exist.
Products stay genuinely valuable to the people who use them. Growth never comes at the cost of product integrity.
Every decision is measured against long-term impact, not short-term extraction.
The entire stack runs on our own hardware in Denmark — no hyperscaler, no US cloud. Your data stays under Danish and EU jurisdiction, not someone else's terms of service.
