Otto

Otto makes it easier to become a great pet owner by leveraging your pet's data to connect you with personalized services and content. In practice that means designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. They also list Internet of Things, Mobile Apps, Pet and QR Codes, so expect those to show up in the feature set. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Otto is based in San Francisco, California. You can read more at otto.pet.
