By “based on” I don’t mean a shared codebase or features but rather Parker and I exchanged emails a decade ago to discuss business models and open source funding. He initially copied my Sidekiq OSS + Sidekiq Pro business model, with my blessing.
This is absolutely true (except we went OSS + Web initially, Pro came later). You were an inspiration, always helpful in discussion, and definitely paved the way for this business model.
