QuestDB is open source and therefore free for everybody to use. Another product using QuestDB as a library with features that are typically required for massive enterprise deployment will be distributed and sold to companies through a fully managed solution.
Our idea is to empower developers to solve their problems with QuestDB open source, and for those developers to then push the product within the organisation bottom up.
I'm not associated with QuestDB, but if it's anything like the other open-source startups I work with then the business model is probably selling a managed or hosted version of the DB with enterprise benefits like security compliance, SLAs, and engineering support. In that case the open-source DB will act as a driver of awareness and of demand for the commercial option.
