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 placement policy that is the same for every vendor and published in full, a small editorial team that has actually bought and run the software it reviews, and two statistics offices — the World Bank and Eurostat — cited directly rather than paraphrased.

How we're funded

Some vendors pay to be listed, and that payment can move where they sit within a ranking. It never changes what we write about them, and it is disclosed once, clearly, rather than buried in a footnote. Full detail is on our placement disclosure page.
