According to Crunchbase, Neo4j was founded in 2007! Is this correct? 14 years in and they are still raising VC money!?
By that time, the share is pretty much what it's worth. But 100 times round A. If all went well of course. Over 90% of the time, it didn't go well. Who knows how that will end for Neo4j, but the investors have their eggs in many other baskets anyway.
What matters isn't showing profit anymore, not even significant revenue to justify further funding. All you need is some appealing growth figures, sometimes not even that, just a convincing argument that hyper growth is on the horizon.
At some point millions are put into advertising and a strong sales force to grow revenue many folds. In the enterprise market, the trick often works pretty well.
