Disclaimer: I know nothing about Neo4J or their pricing structure. To be fair, though, niche products are often very expensive because there aren't many customers to pay for the development. If you have a million paying customers you can charge them $10 a year each and fund a reasonable sized company. If you have 5, then you need to charge them $2 million each ;-) Having said that, I tried to find pricing information on their website and couldn't find it. For me that's a sign of "If you have to ask, you can't afford it" level of pricing...
