I think that a much cleaner messaging on what this tool is for would help.
Also a question about the implementation, why DuckDB for a CRM?
Something like SQLite feels like a much natural fit for a CRM where you primarily create, update and maybe delete records and you really care for the integrity of the data model.
From a quick look on the data model, everything seems to be a VARCHAR, if this is the case, why not just store everything in the file system instead? You do that with the md files and whatever is getting extracted from the SaaS tools.
