App development for the tourism businesses in this list, on a revenue share

A first step

Pick one idea from this list that already runs as a small tourism business, such as a whale-watching boat or a fish-market tour, and build its booking page for free on a revenue share. Measure bookings for a month against the month before. If the owner earns more, their numbers are your pitch to the next 10 businesses.

Who pays first

A small tourism operator who cannot pay upfront for software but will share a slice of each booking it brings in.

What leaves today

Small tourism businesses sell through foreign booking platforms that take a commission, or do not sell online at all.

The idea and the mechanism are from the book. The first step was written for this site as a suggestion; if you know a better one, say so.

The test

Does it keep value that now leaves the island, or build the proof that lets somebody else do so?

The only test any idea on this site has to pass. The four rules that go with it are here.
