> We'd prefer to keep as open as possible and have a commercial SaaS or open core model

Isn't this opposed to this?

> We really don't like the 'traditional' open source economic model - with a community version and all the good features in a proprietary enterprise edition

This is what I thought open core was, am I wrong?

A commercial SaaS model would make a lot of sense for a project that wants to remain completely free software, though. You are the people who know your code best, and it makes sense to trust and pay you to run it reliably.
