Btw, Swifttype, which is in the upper right corner is a company that is built on Elastic and that Elastic bought last year.
Another example of Elastic not able to create products that are as good as third parties can build (for not much cost) on top of Elastic, but Elastic trying to monetize this by buying them out.
Thus Elastic’s entry into enterprise search. Is Swifttype (revenues are not sky high here, but it is said to be a great product and is SaaS), and their own Elasticsearch product that Elastic recently (mid last year I think) gave a nice upgrade trying to go beyond just regular enterprise search and consolidate all searches into the enterprise search. Elastic explained it in their product release PRs last year.
As to how much money it makes?
