// EDITOR'S TAKE
Be honest about the gap: no open source project replicates waterfall enrichment across paid data vendors, because the value is in the data contracts, not the software. Twenty is the closest starting point since its API and custom objects let you script enrichment into records yourself, while EspoCRM is more capable out of the box with workflows and a dated interface, and ERPNext only makes sense if you want sales sitting inside a full ERP.
