What they did

The author gave it access to a local folder and, with simple requests, the agent downloaded Adyen's reports, transcripts and data and wrote a business overview, an Excel model with a 3-scenario discounted cash flow and comparables, a thesis memo and a one-page summary. Then it scheduled a weekly update.

How it went

According to the author, the whole workflow took less than 15 minutes.

Good to know

A nice-looking model is no guarantee; check the assumptions and sources before investing.
