Contact & data model
HubSpot Sales Hub
Deals-as-pipelines up to 100 and 'smart properties' runs tell me a real relational model with custom properties exists, but the evidence is silent on deduplication, merge, field validation and permissioned field access — for a database of other people's personal data, unevidenced hygiene is unevidenced hygiene. Slightly above the cosmetic-customization floor only because the pipeline model is clearly substantial.

Leads and deals reach even the free tier, and teamspaces, wizards, custom functions, territory management, time-stamped audit logs and Vaults for private business data give the record layer substance. We found no public information on deduplication, field validation or field-level permissions, so the hygiene of a database full of other people's personal data rests unproven.
