I tried to build and sell a CMS and frontend-as-a-service for 3 years. We "failed" as in not-rocketship-revenue. Now we are on board the software factory train and we are _replacing_ the services companies that used to operate our software. Now we are growing 20x faster. Welcome to the brave new world of Service as Software, I guess! Testing this mostly in Brazil/enterprise, launching support for Shopify this month.
