Sonation

Sonation apps make singing and playing music more fun and interactive. In practice that means building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. Alongside the main category they mention Music and Professional Services. 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.

Sonation is based in Boston, Massachusetts. More on sonation.net.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. Get the renewal terms in writing before the first invoice.
