Prior to starting WunderGraph, I've worked for a Full Lifecycle API Management company. It's was my best paying and most satisfying job before cutting my salary almost half to make my startup burn as little as possible.
I found this company because they had an open source codebase, written in Go. Coincidentally, I've built a library (https://github.com/wundergraph/graphql-go-tools) to build GraphQL API gateways, also written in go. At that time, they were only supporting REST. So I wrote them and offered the opportunity to add GraphQL to their API management capabilities. That was it, perfect match. Fast forward 2.5 years later and they have all sorts of powerful GraphQL API management capabilities. I think it was great for everyone involved.
So it's not about loving s company or a cult or anything. It's a about finding a good match between candidate and employer, and making it super easy for the employer to "spot" that from the very beginning.
