HubSpot vs Salesforce through customer evidence
Both sides include public evidence of customer-facing sales workflows. Salesforce examples include Siemens and Spotify Advertising. HubSpot examples include Casio UK and Ireland, Avison Young, and a CRM-purpose disclosure from Linear.
The sample was selected for inspectable evidence, not market representativeness. Differences in observed counts do not establish which vendor is more popular, better, or growing faster.
Read company overlap carefully
A company is counted once per provider using its normalized domain. A repeated source cannot increase its count. The overlap denominator is the union of companies on the two sides, not the sum of provider counts.
No shared company in a filtered sample means no shared observation in that sample. It does not prove that organizations never use both products. Different entity boundaries and source scopes can also affect apparent overlap.
Migration evidence and CRM selection
A useful migration claim needs a named starting system, ending system, service scope, and supported timing. We do not interpret a newly reviewed customer story as a recent switch.
For selection, define the sales process, reporting requirements, integrations, and ownership of CRM data. Use the customer evidence as a starting point for research, then validate the actual product configuration and implementation requirements.
