Read maybe not, but I was there if you are curious about anything.
I was there during the transition period. Originally joined to work on the Meteor hosting platform that was called Galaxy. Handled integration of Meteor APM (which was an acquisition) both of which got sold off when the old Meteor business was sold.
I then worked on what was called Apollo Optics, the GraphQL APM product. Rewrote the time series backend to port it to Apache Druid (which remains in use today!). Was somewhat unceremoniously let go of during a bad personal period. Don't think I would have stayed anyway though, main reason I stayed as long as I did was I had a really good mentor there that taught me a lot.
Worth mentioning the company had already raised an absolute crap ton when on the original Meteor path, then the following pivot raised even more money. No idea how many rounds of financing the company has been through at this point but to say it exemplified the excesses of cheap money would be an understatement.
Developer tools is a tough business, no-one really wants to pay for that stuff at the low end which means catering to enterprise. Long sales cycles, annoying requirements etc.
I'm not sad about it, turned out really well for me.
I believe the compelling part of the current offering is the schema management features. We started building these when I was there. I don't know to what degree the alerting part of the APM product survived. It was originally requested by an enterprise customer and I re-implemented it on-top of Druid to make it much more scalable. My assumption is that should be a bit of a draw. etc.
Also, big aside here, but is Meteor still a thing?
