I think this is a demonstration of the limits in "app-ing" an industry. Uber worked fantastically because it leans heavily on the geolocation facilities in a smartphone - you're always moving, getting picked up from different places, by cars located in different places.

Homejoy had none of that. You rarely move home, and your cleaner rarely does either. Effectively, from transaction #1 you're in a perfectly replicable pattern - Cleaner X comes to your house every Y weeks and works for Z hours. No matter how great that initial app experience is, it's basically not needed afterwards.

There's also something interesting in here about the limits of the "gig economy". Arguably, by creating a marketplace of cleaners competing with each other for your money, they'd drive costs down for customers. In reality, inviting someone into your home is a very personal thing, and people much prefer to build a relationship with someone that they might pay a little more on a regular basis, than get a different person each time. It is a premium service, after all.
