I don’t normally celebrate venture funding because customer money, not VC money, is the best signal of success. That said, $325 million is a lot of money. That’s how much Neo4j, an open source graph database company, recently raised. When I was at MongoDB, we raised $311 million, but that was spread across a number of funding rounds; $325 million, all at once, is mind blowing.
Graph databases, once wrongly considered niche, are finding their way as general purpose databases. In fact, this is arguably the real lesson from Neo4j’s successful fund raise: graph databases are very much mainstream.
