Proof of Usefulness Score
Gaining Momentum

The project 'Castor' (CastorDoc) is a high-utility, valid B2B data discovery platform with significant real-world value and market relevance. However, the submission itself is of extremely poor quality, conflating the data catalog tool with a separate 'Electronic Data Capture' company (Castor EDC) and providing blatantly false/lazy traction claims ('most people have used my product', 'everyone'). The score reflects the strong underlying business fundamentals of CastorDoc, heavily penalized by the lack of verifiable evidence provided and the inaccurate metadata in the submission.

Description
Castor is a collaborative, automated data discovery tool (https://www.castordoc.com).\n\nWe believe that data people spend way too much time trying to find and understand their data.\n\nCastor relieves this pain by redesigning how data people collaborate. It provides a single source of truth to reference and document all the knowledge related to data within your company.\n\nIf you are looking for a table related to your customers, just look for it as you would in Google and Castor provides you with all the context you will need in your analysis.\n\nInspired by tech giant internal tools (Uber’s Databook, Airbnb’s Data Portal, Lyft’s Amundsen, Spotify's Lexicon), we have developed a plug \u0026 play solution for all companies. Castor has the specs and quality of the tech giants data discovery tools available in few minutes as a ready-to-use SaaS.
