AI for Lawyers: 300 Features, They Used One | Rowan McNamee, Mary Technology
“The customers make you undeniable — not the founders.”
Before he built an AI for lawyers, Rowan McNamee took the notes himself — sitting across from people mid-divorce, writing down their custody disputes by hand.
Rowan co-founded Mary Technology, an Australian legal-tech startup that turns thousands of pages of case documents into chronologies, summaries and reports. He walks through the failed first prototype that gave lawyers 300 ways to use a transcript when they only wanted one, why Mary turns down every transactional and M&A case to stay purely litigation and disputes, the architecture built to stop AI hallucinating across thousands of documents, what changed in him once real clients' worst moments were riding on getting it right, and why the company is named after his aunt.
