Editorial interest 89/100 Selection signal · not a rating of the site

A technical-diligence service for deep-tech investors that searches doctoral dissertations for failed methods, rejected designs, and unfinished work.

Landing page captured for the 2026-09-02 issue.

Field notes

The service says it extracts evidence that conventional papers omit: the method that lost, the design an author rejected, and the work they said remained worth doing. Its stated dataset spans 22,537 dissertations from 22 institutions, including 49,915 documented failures and 73,688 unfinished-work items. A sample comparison follows active-learning claims across Georgia Tech, Imperial, MIT, and UT Austin, with the page presenting four cases where random sampling matched or beat the proposed approach.
