We build software you can check.

Assay is made by Ferrolo, a small software studio.

Why we made Assay

Every team we spoke to had the same spreadsheet: a scorecard, a handful of calls per agent, and a nagging sense that the problems were in the calls nobody had time to hear.

AI tools promised to read everything, but when we asked where a score came from, the answer was a paragraph written by a chatbot. That isn’t something you can show an auditor.

So we built Assay around one idea: every result should point to the line that caused it, and when the software isn’t sure, a person should decide.

Evidence first

If we can’t show you why, we don’t claim it.

People decide

Software handles the clear cases. People handle the close ones.

Plain language

Rules, results and settings are written for the people who use them.
