Really sad end for Heroku. They never could find a balance between the free tiers they offered and their overly-expensive paid tiers. Now they're entering purgatory before they are ultimately shut down for good. They had the markings of a long-lasting company in this space but corporate mismanagement has led to this drawn out death for the company. Salesforce buying the company made a few rich, but it really did turn…
I think the struggle is that Salesforce has never historically offered a platform as a service business that is agnostic to its end goal. I imagine the idea of acquiring Heroku was to make it easy to spin up new Salesforce apps, but I don't know that ever materialized in the way they were hoping.
