Ex. A user wants to try it out but paying for a custom domain scares them. They stick to a free subdomain, but never really promote it since it conflicts with their own branding.

Admittedly you're making a good point here that users _would_ get more value this way through increased branding.

I think giving your customers what they want is the central theme behind most of our advice

Absolutely, but would charging them for a (technically) trivial feature be self-limiting to our growth?

Another question: Would be worthwhile to apply to YC with a product of this nature?

This was super helpful. Thank you for taking the time Michael.

Addressing your first point, Heroku charges $20/mo for HTTPS support and plenty of people pay for it: https://elements.heroku.com/addons/ssl

You're right, that's a good example. Thanks!
