Exactly. Kudos on building a fairly complex application over the weekend, but the journey has just begun. 'Build it and they will come' does not apply (usually) for revenue generating businesses with real customers.
You're right in that it's not a profitable business yet. It's only a business in that we offer a service and we charge for it. We definitely don't do that profitably yet! We've built a minimum viable product that we'll use as a basis to explore and define demand.
That's cool, what you've built in such a short time is great and I wouldn't take away from the achievement... I'd just change the post title :-).
