I'm interested in how Quiver is going? It looks like this is your main revenue stream? I've looked at it before and been unsure what it does, and trying it now it doesn't seem to work for us (no requests ever reach quiver with the GraphQLQuiverCloudBackend). Is it production ready, or is it in preview at the moment?
Edit: so the issue was that we had an extraneous trailing comma, which was turning a string (deprecation reason) into a 1-element tuple, which was then failing an assertion in the AST serialisation within graphql-core, however this assertion was being silenced by one of the backends - either the decider or the Quiver backend.
I started working on it almost 3 years ago. Now about 5.000 companies all over the globe are using it including Yelp, Reddit & Mozilla.
We're profitable and trying to expand our niche (GraphQL in Python) to more markets. Thinking on applying to YC in not a very far future :)
