Privacy-first SaaS ideas

Here’s a dopey idea:

Create a privacy-first alternative for any popular SaaS you know. Anything. Everything.

More and more consumers are trusting big companies less with their data. Many SaaS have carved out a niche for themselves by just offering privacy-first as the main benefit.

Simple Analytics, Fathom Analytics and Plausible comes to mind, as privacy-first alternatives to Google Analytics.

Also:

• Logseq for knowledge base
• SoapBox for voice AI

This also appeals to business customers—maybe in the EU?—who wants to be GDPR compliant and not run afoul with other privacy laws.

So how about privacy-first alternatives of these popular SaaS?
