I'm curious what a Jenkins + Octopus system is missing that your system provides. Most companies would have a hard time justifying the expense to build a bespoke system just for devops.
Jenkins/octo, as tools, have their place but are just parts of the tooling you need when things go business critical or when teams scale up.
Most companies that run business critical services would be spending wisely putting effort down in building or customizing dev tooling and automations.
