AI Engineering Playbook

Methodology

What goes in

Public statements by companies (memos, engineering blogs, earnings remarks, executive posts) and reporting by established outlets. Each claim is stored with the indexes of the sources that support it, and each source has a title, URL, publication date and type.

Source types

Mandate classification

Editorial fields

Industry and size bands (Under 5k employees, 5k-50k employees, 50k+ employees) are editorial approximations, not sourced claims, unless a source marker appears next to the size on the company page.

Dates

Dates are the source's publication date. Where a page shows no date, the date comes from page metadata, the URL path (month-level, e.g. 2025-11) or a dated secondary report; the company page notes this.

Verification

All source URLs were checked on 2026-10-25. Some sites block automated checks; those were confirmed by loading the page another way.

Scope

The database currently focuses on technology, software and fintech companies. Fintech entries are not banks, and this is noted on their pages.
