Vibe coding CRM is totally doable. Anyone who told you you need Salesforce or other complicated CRM to run your business is wrong at this point.
The more fair point is, if your company is legacy and has been running on Salesforce, you will continue to do so. That's more true.
If your company is new from day 1, you would be out of your mind to adopt Salesforce rather than asking AI to program your own data/opportunity/deal data model that fits your own business. Integrations are not that hard either with API, CLI, MCP, connectors.
We just live in a new world. Let's face it.
