You've done the easy bit. The hard bit is how to make money. Selling to the apartment owning/building/management industry will be very difficult. The product needs to be a lot more refined. The marketing materials just so. The team selling experienced in the industry. And so on.

Some fights are worth having. If you can find a sidekick who relishes the sales battle then sobeit.

Else consider open sourcing what you've done and move to the next problem.
