About The Interregnum

The Interregnum ranks business software and publishes industry data at the point where a market is visibly changing shape — a new regulation, a wave of consolidation, a category moving from on-premise to cloud. The shift we follow most closely is the one running through every category at once: from conventional software to software built on AI. We built it because most software comparison sites read as though the market they cover never moves.

The site runs on three things: a published placement disclosure, a single named editor who is accountable for every page, and two statistics offices — the World Bank and Eurostat — cited directly rather than paraphrased.

How we're funded

Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. We say so on every ranking rather than in a footnote. Full detail is on our placement disclosure page.
