Maybe Elastic isn't growing because Algolia is eating their lunch?
but I think mission-critical search is a niche technical problem that isn’t applicable to many enterprises.
Entire ELK stack was always pretty bad, compared to Splunk or a syslog server and grep, in my opinion.
We tried to buy a support contract from Elastic years back, but the pricing model put all useful levels of support way beyond our reach. Apparently they didn't understand that we had to make our money and didn't have VC funding.
