This has to be one of the worst analogies I've ever seen. This business model is nothing like Airbnb. It's more closely aligned with something like TemplateMonster, eLance, or oDesk.

I see no way you can rent out a algorithm for a business use and lease basis..which is what Airbnb is.

Other then that this I see the reason that something like this exists. Creating accurate mathematical formulas is definitely an art in itself that not just anyone can do.
