+305
Proof of Usefulness Score
Certified Problem Solver

Heptabase is a high-quality, Y Combinator-backed visual note-taking tool with verifiable revenue and a strong user base, despite the submission containing lazy and inaccurate claims (e.g., 'everyone', 'most people'). External analysis confirms strong product-market fit in the PKM (Personal Knowledge Management) sector, profitable operations (~$2M+ ARR estimated), and significant innovation in visual interfaces. The score reflects the high quality of the actual project, penalized slightly for the poor quality of the submission data.
