A company in Switzerland has an interesting business model:

You buy a bee hotel (or bee hotels). They provide you with a tube containing a few fresh bee larvae every year before the wild bee season. After the season, you return the filled tubes. They remove parasites etc. and sell the resulting bee larvae for their commercial business with farmers etc. The biannual exchange is free. There is also minimal gamification because you can compare your success with other bee hotel owners from the same company.
