This is a half-joke of a comment, but I would pay $50/month to a product that could explicitly prohibit the CEO from editing the production database.

I saw this immediately after submitting my comment above and I was like why would you want to give such access to someone who is more than likely non-technical. I can't see any pros from this unless it's locked to read only mode but then at $50 you're just paying for an excel view into your app.

In a startup, are you sure you like to spend 600 bucks on a db edit tool - what stage is your startup ?

I disagree, speaking on production data, if your CEO is technical enough they should be able to do this (for whatever reason they have).

If not, you need some sort of admin interface (could be a couple forms) to address this properly so invalid data can't be plopped in OR any changes should be documented and sent to someone technical even if it's a typo fix. It seems fun and easy but production data isn't something you should wrap in an excel interface and give to any and everyone. $600 a year so your boss can update names and dates is kinda hard to justify as well.
