Louder.com

Louder.com is an online platform that offers a wide range of new and used musical instruments to various of its customers. In practice that means running an online store from catalog to checkout.

The natural audience is retailers and brands. Alongside the main category they mention E-Commerce and Music. They are a very small team, 1 to 10 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Louder.com is based in San Francisco, California and founded in 2016. You can read more at louder.com.

Things worth asking about: transaction fees, themes, and app ecosystem. A short pilot with your real data tells you more than any demo.
