Yes, the license for Bloom is separate from the license for Neo4j Enterprise Edition (which you're using as part of the startup programme). In Neo4j Desktop you can use Bloom to connect to local databases running inside Desktop without an additional license (it's all included as part of Desktop). In order to connect to a remote server using Bloom in Neo4j Desktop, that server has to be running Bloom as a server plugin (a .jar file just like APOC, etc.) - and the server plugin does require a valid license key. I don't know the particulars of licensing Bloom for the Startup Programme, so if you're interested in getting a server key I'd recommend reaching out to your contacts in the sales team or startup programme. If you need help finding the right person to get in touch with let me know!
