DataClean: the HubSpot duplicate hunter

Why it surfaced

This is a sharply focused CRM tool aimed at the duplicates that exact email and phone matching misses—“Jon Smith” versus “John Smith,” for example. It offers review-before-merge workflows, formatting standardization, and a free tier for up to 1,000 contacts; the site also openly describes itself as solo-built and welcoming beta testers.

DataClean finds and merges duplicate HubSpot contacts using fuzzy, phonetic, and domain matching, with CSV cleanup before import.
