OASIS

OASIS is a not-for-profit consortium that brings people together to agree on intelligent ways to exchange information over the Internet. The job it does: building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. They are a small team, 11 to 50 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.

OASIS is based in Burlington, Massachusetts. More on oasis-open.org.
